Master student at University of Prishtina (UP), Nita Mulliqi is conducting her thesis research at Norwegian University of Science and Technology (NTNU) in Gjovik, Norway, as part of an Erasmus+ mobility grant by EU. Indicated work is accomplished under the supervision of Prof. Dr. Lule Ahmedi at UP in conjunction with Prof. Dr. Sule Yildirim, Prof. Dr. Hao Wang and Prof. Ahmed Kedir at NTNU.
Research area is focused on the rapidly developing field of computer vision, and its utilization in extensive medical data in order to provide accurate diagnosis and prediction of cancer disease. The aim is to develop an intelligent system which will be able to identify cancer in human colon as well as it will act ethically and legally correct corresponding to this matter. Using advanced deep learning architectures, the system will conduct medical image segmentation and classification tasks in order to detect whether data provided indicates cancer or non-cancer input. Data being used from the system are images extracted from videos of colonoscopy screening technology. Colonoscopy videos are provided from "ASU-Mayo Clinic Colonoscopy Video Database" as the largest database with sets of colonoscopy videos. These videos are collected and re-identified at the Department of Gastroenterology at Mayo Clinic in Arizona, US.
A Deep Learning master thesis work in cooperation with University of Freiburg resulted to a publication "Detecting Biased News Articles Using Convolutional Neural Networks" presented at SemEval@NAACL-HLT 2019 in Minneapolis, USA.
The project began as a solution for the Task 4 of the international competition for computational semantic analysis called SemEval-2019. The task is, given a news article text, decide whether it follows a hyperpartisan argumentation, i.e., whether it exhibits blind, prejudiced, or unreasoning allegiance to one party, faction, cause, or person. The automatic news classifier, which is based on a Deep Learning model and uses Convolutional Neural Networks (CNN) to detect the articles features, is developed by Master student of the University of Prishtina, Agon Qurdina, under the lead of Prof. Dr. Lule Ahmedi from University of Prishtina and Dr. Michael Färber from University of Freiburg. As part of the competition, the project was granted the right to be presented at the SemEval workshop in the 2019 Annual Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies (NAACL-HLT), which is held in Minneapolis, USA, June 2-7, 2019.

Wireless Sensor Networks (WSNs) are one of the most important components of the Internet of Things (IoT). They produce continuous stream of data and transmit these data to a centralized server. Due to the dramatic increase of streaming data, their management and exploitation has become increasingly important. Furthermore, by adding semantic annotations into sensor stream data, better understanding and more meaningful descriptions is provided, which enables application areas of IoT to become much more intelligent. In this paper, a data stream management model of WSNs for IoT real-time monitoring systems, that supports real-time integration of data from heterogeneous sensors with semantic annotations is presented. To validate the proposed model, an IoT system for real-time water quality monitoring is built, which enables real-time integration of semantic annotations to the sensor stream data in the format of Sensor Observation Service (SOS).
Recently, billions Internet of Things (IoT) devices, including sensors are producing sensed data continuously in the stream data, and transmit these data to a centralized server. Due to the dramatically increase of streaming data, their management and exploitation has become increasingly important and difficult to process and integrate the semantic to sensor stream data in real-time. This research focuses on real-time integration of semantics into heterogeneous sensor stream data with context in the IoT. In this context, an IoT real-time air quality monitoring system and different semantic annotations are developed for sensor stream data in the format of Sensor Observation Service (SOS).
A shift in water monitoring approach from traditional grab sampling to novel wireless sensors is gaining in popularity not only among researchers but also in the market. These latest technologies readily enable numerous advantageous monitoring arrangements like remote, continuous, real-time, and spatially-dense and broad in coverage measurements, and identification of long-term trends of parameters of interest. Thus, a WSN system is implemented in a river in Kosovo as part of the INWATERSENSE project to monitor its water quality parameters. It is one of the first state of the art technology demonstration systems of its kind in the domain of water monitoring in developing countries like Kosovo. Water quality datasets are transmitted at pre-programmed intervals from sensing stations deployed in the river to the server at university via the GPRS network. Data is then made available through a portal to different target groups (policy-makers, water experts, and citizens). Moreover, the INWATERSENSE system behaves intelligently like staying in line with water quality regulatory standards.

Nowadays with the raised necessity to serve data through the Web in a rather Linked Data model similar to the way DBpedia extracts structural information from Wikipedia, it is becoming usual to require existing data provided as tables to get mapped into RDF. In this paper, a straightforward alternative to mapping of data from relational database model to RDF is introduced. The mapper has not yet reached its maturity but nevertheless, reduces greatly the amount of time needed for conversion. Furthermore, it allows the user to select parts that are needed for conversion, thus preventing from the unnecessary conversion.
Recommending the adequate point of interest (POI) for a specific tourist visiting a new place/city, remains still a challenge for all recommender systems that today exist, consider-ing the metrics that each system takes into consideration. ViziTo is a system which recom-mends a touristic POI for a tourist, based on bimodal social network analysis (SNA) and its specific metrics. In this demo, a web portal is presented, in which a user after registering or signing in as a tourist, given his/her personal profile (i.e., age, gender, etc.) and touristic preferences for a certain type or category (like nature, archaeology etc.), via its recommender algorithms will recommend to tourists' certain POIs.
The Internet of Things (IoT) vision is to connect uniquely identifiable devices that surround us to the Internet, which is best described through ontologies. Thereby, new emerging technologies such as wireless sensor networks (WSN) are recognized as an essential enabling component of the IoT today. Hence, given the increasing interest to provide linked sensor data through the Web either following the Semantic Web Enablement (SWE) standard or the Linked Data approach, there is a need to also explore those data for potential hidden knowledge through data mining techniques utilized by a domain ontology. Following that rationale, a new lightweight IoT architecture SEMDPA has been developed. It supports linking sensors and other devices, as well as people via a single web by mean of a device-person-activity (DPA) crossroad ontology. The architecture is validated by mean of three rich-in-semantic services: contextual data mining over WSN, semantic WSN web enablement, and Linked WSN data. SEMDPA could be easily extensible to capture semantics of input sensor data from other domains as well.

With the progressive role of computers and theirusers as actors in social networks, computations alikesocial network analysis (SNA) are gaining in attention. This work proposes an approach based on SNA, not alone on social networks as supported by existing approaches, to estimate the tourists' satisfaction with individual Points of Interest (POIs), and accordingly recommend those POIs or not to that tourist or its tour planning system. Moreover,instead of a common unimodal network, a bimodal tourist-reviewer network is modeled as suggested by the SNA literature given tourists and POI reviewers act as two distinct classes of entities with links between them representing their (dis)similarities. Both tourists and reviewers provide their personal attributes (like age), but reviewers then providing preferences for speci?c POIs, whereas tourists only preferences for certain types or categories of POIs (say archeology). Further, an algorithm for grouping into ''islands'' of most similar reviewers to a certain tourist given the strength of corresponding links in the bimodal network is developed. Additionally, a ranking algorithm based on in-degree or authority centrality is adopted to identify the highest ranked reviewers within the island and recommend their preferred POI s to a given tourist. If there are more than single POIs preferred per reviewer, and there remain more than requested POIs of the highly ranked reviewers to select among for recommendation, a similar centrality algorithm is applied over a reviewer-POI network with links representing a certain reviewer prefers that certain POI. The evaluation initially with an exemplary real-life experiment, and then extended to a massive online dataset from Foursquare, proves our approach as feasible inestimating the tourist's satisfaction with individual POIs. Moreover, it is already promising since incorporating location in?uence remains yet our future work and might further improve its performance.

The synergy of Data Stream Management Systems and Semantic Web applications has steered towards a new paradigm known as Stream Reasoning. The Semantic Web standards for knowledge base modeling and querying, namely RDF, OWL and SPARQL, has extensively been used by the Stream Reasoning community. However, the Semantic Web rule languages, such as SWRL and RIF, have never been used in stream data applications. Instead, di®erent non-Semantic Web rule systems have been approached. Since RIF is primarily intended for exchanging rules among systems, we focused on SWRL applications with stream data. This proves di±cult following the SWRL's open world semantics. To overcome SWRL's expressivity issues we propose an infrastructure extension, which will enable SWRL reasoning with stream data. Namely, a query processing system, such as C-SPARQL, was layered under SWRL to support closed-world and time-aware reasoning. Moreover, OWLAPI constructs were utilized to enable non-monotonicity, while SPARQL constructs were used to enable negation as failure. Water quality monitoring was used as a validation domain of the proposed system.

Association rule mining as descriptive data mining category aims to find interesting patterns on data. The quality of the patterns is measured with two metrics: confidence and support. Especially in fields dealing with sensitive data, such as healthcare, the resulting patterns should be novel and interesting. To achieve that, not only the quality of the data itself should be superior, but also other additional attributes added, do support the results. That should be achieved by using Semantic Web technologies and thus enriching data used with semantic relations between properties. A hypothesis suggests that especially tackling property relations, chain property being part of the current version of the W3C Web Ontology Language (OWL), will yield better rules. To validate the hypothesis, experiments were performed on raw data, then on an older version of OWL, which does not support the chain properties and finally on the current version of language involving chain properties. Results obtained suggest that the latter produces novel rules with strong confidence and support, not encountered in former two experiments.
The recent proliferation of Massive Open Online Courses (MOOCs) has initiated a plethora of research endeavors revolving around new pedagogical methods in higher education. Integrating MOOCs in blended learning can be beneficial in different ways for both learners and instructors. In this position paper, we aim to provide a brief and comprehensive review about the challenges that higher education institutions in Macedonia and Kosovo face while coping with the new trends of flexible or blended learning. Moreover, after describing some real cases of MOOC based flipped classroom learning, we also provide some recommendations in order to enhance and enrich learning experience by employing innovative pedagogies.

Semantic technologies have been extensively used for integrating stream data applications. However, using SWRL, which has become the de facto standard rule language in Semantic Web, has never been used in stream data applications. Its open world assumption and monotonic nature makes SWRL powerless for doing continuous inference over stream data. For example, using aggregate functions on a particular window of streams cannot be expressed in SWRL. C-SPARQL is a framework which supports continuous querying over data streams. We introduce here C-SWRL, a unified Semantic Web stream reasoning system that further supports continuous reasoning over stream data. C-SWRL utilizes C-SPARQL filtering and aggregation of RDF streams to enable closed-world and time-aware reasoning with SWRL rules. Moreover, the non-monotonic behavior is supported with the use of OWLAPI constructs. The system is presented by means of examples in water quality monitoring.

Along with general search engines which search the entire web, vertical search engines that are rather focused on specific domains of search have also gained in popularity in web search. In our case we are focused on domain of online shopping. We treat main processes of search engines which include crawling, indexing and query processing. Each process is developed based on general search engines and adapted to tackle the problems of the specified domain. Specifically, a search result ranking algorithm called Warehouse, which may be adapted to rank results of any specific domain, is introduced.
Recommending the adequate query in search engine for a specific user on the web is still a challenge even for recommender systems today with social networks incorporated. In this paper we present a query recommender that in addition to relying on similarity of the actual query posted by current user to queries in a query log in search engine, it also bases on social network analysis (SNA) to first find most similar users to the current user based on their profiles, and then recommend their most similar queries to current user. Calculation of the similarity of users follows an existing approach for Points of Interest (POIs) recommendation, which applies certain SNA ranking algorithms over concurrent users based on their social profiles in the login session.
Stream data knowledge bases modelled with OWL are a proved natural approach. But, querying and reasoning over these knowledge bases is not supported with standard Semantic Web technologies like SPARQL and SWRL. Query processing systems enable querying, but to the best of our knowledge, Semantic Web rules are still unable to handle the required reasoning features for effective inference over stream data, i.e. non-monotonic, closed-world and time-aware reasoning. In absence of such a system, we showed in our previous work how Jess can be used for monitoring water quality, but by bringing input data manually. In this paper, we enable stream data support and thus a timely detection of faulty water quality statuses by also extending our ontology with the pollutants module. C-SPARQL abilities to filter and aggregate RDF streams are utilised to enable closed-world and time-aware reasoning with Jess rules. Moreover, Jess Tab functions are used to enable non-monotonic behaviour.

Internet of Things (IoT) applications by means of wireless sensor networks (WSN) produce large amounts of raw data. These data might formally be defined by following a semantic IoT model that covers data, meta-data, as well as their relations, or might simply be stored in a database without any formal specification. In both cases, using association rules as a data mining technique may result into inferring interesting relations between data and / or metadata. In this paper we argue that the context has not been used extensively for added value to the mining process. Therefore, we propose a different approach when it comes to association rule mining by enriching it with a context-aware ontology. The approach is demonstrated by hand of an application to WSNs for water quality monitoring. Initially, new ontology, its concepts and relationships are introduced to model water quality monitoring through mobile sensors. Consequently, the ontology is populated with quality data generated by sensors, and enriched afterwards with context. Finally, the evaluation results of our approach of including context ontology in the mining process are promising: new association rules have been derived, providing thus new knowledge not inferable when applying association rule mining simply over raw data.

Wireless sensor networks (WSNs) are aiding water quality monitoring with support for real-time and remote quality measurements in terrain. Environmental monitoring portals receiving data from sensors have been a practice since a while among researchers. However, the Web portal introduced here is essentially an integrated portal since it supports modeling and management of both, the observational stream data on water quality coming from wireless sensors - dynamic data, as well as of the data describing the WSN itself, its devices and the corresponding site allocation data - static data. Access is given to a wide range of individuals, from water experts to WSN engineers, to general public. Experts' module infers statistics about water parameters given the experts' data and rules. The portal is further distinguished for its level of scalability: it allows adding with ease new components, like add certain new regulatory documents for water quality, and directly compare data measured by sensors with corresponding quality standards. The aim is to enrich the portal with semantics in future.

Semantic technologies have proved to be a suitable foundation for integrating Big Data applications. Wireless Sensor Networks (WSNs) represent a common domain which knowledge bases are naturally modeled through ontologies. In our previous works we have built domain ontology of WSN for water quality monitoring. The SSN ontology was extended to meet the requirements for classifying water bodies into appropriate statuses based on different regulation authorities. In this paper we extend this ontology with a module for identifying the possible sources of pollution. To infer new implicit knowledge from the knowledge bases different rule systems have been layered over ontologies by state-of-the-art WSN systems. A production rules system was developed to demonstrate how our ontology can be used to enable water quality monitoring. The paper presents an example of system validation with simulated data, but it is developed for use within the InWaterSense project with real data. It demonstrates how Biochemical Oxygen Demand observations are classified based on Water Framework Directive regulation standard and provide its eventual sources of pollution. The system features and challenges are discussed by also suggesting the potential directions of Semantic Web rule layer developments for reasoning with stream data.

Author ranking is growing in popularity since search engines are considering the author's reputation of a Web page when generating search results. A question that naturally arises is whether we should rank authors on the Web as we rank Web pages by considering their links. In addition, over what links to actually calculate author ranking? We have adopted an extended FOAF ontology, the so-called Co-AuthorOnto ontology, able to represent authors, but also their co-author links on the Web. We further extended Co-AuthorOnto with PageRank and AuthorRank metrics for ranking authors based on their co-author links. Important to note is that both PageRank and AuthorRank are implemented in Semantic Web Rule Language (SWRL), which represents a novelty and fits well with the semantic modeling of authors and their co-author relationships within FOAF. Preliminary semantic ranking results are demonstrated, showcasing also the huge potential of this ranking approach for adopting it by search engines where our future work will focus.

Although Semantic Web builds on well-established foundations and we are witnessing its expansion across multiple domains, the community has to-date been rather keen on building hybrid ontology-based water quality management systems. Our vision is to build a pure Semantic Web framework for effective management of water quality. In line with this, an SSN-based ontology for water quality management has been developed to support water quality classification based on different regulation authorities such as Water Framework Directive. A couple of case studies from surface waters and drinking waters have been used to illustrate the usability of the proposed ontology.
Information and Communication Technologies (ICTs) present the technological fundament of the information and knowledge based society. Kosovo has a chance to improve the wellbeing of its citizens through technology-enabled industries and services. Moreover, the results delivered by ICT R&D may be well used by many other disciplines of science and technology. In addition, ICTs are the main driving engine of innovation in a modern society, and as such should be given the attention they deserve.
Kosovo has recently improved in ICT performance. However, existing research infrastructure and resources are scarce, and investments should follow to support research in ICT. There is an urgent need for enabling technologies for building an information and knowledge based society.
The project "Co-ordination of Research Policies with the Western Balkan Countries" (wbc-inco.net), funded by the EU under the FP7 Programme, aims to contribute integration of the Western Balkan Countries into the European Research Area. As part of that project, this national background report on ICT research for the period 2009-2013 has been prepared.
The report first outlines the current ICT research environment in Kosovo, i.e., the local policy framework, fields of competencies in ICT research, the ICT sector trends, and the main socio-economic challenges that affect the R&D in ICT field. Involvement of Kosovo in EU research projects with an emphasis on ICT is then discussed, followed by a SWOT analysis of the ICT research capacity in Kosovo
Finally, the national background report introduces ICT research priorities on the basis of the country's readiness, as well as priorities on the basis of future potential. A summary of the consultation process conducted is also presented in the report. Although in a tight priority competition, 10 priorities were identified to represent the highest ICT research priorities of Kosovo for the period 2009-2013. For each priority, specific (socio-economic or other) objectives are defined, and a set of research topics per objective listed accordingly.
In terms of a wider objective, the national background report on ICT research is intended to contribute to the shaping of future research cooperation between EU and Western Balkan countries by funding programmes and policies of EU research that meet the actual needs of regional ICT domain.
The FOAF ontology has become a core model for describing social data of people and their links on the Web, and the people ranking is growing in popularity since search engines are considering the author's reputation of a Web page when generating search results. FOAF alone is yet insufficient to model social networks for ranking people on the Web. We concentrate here in co-authorship networks as a special case of social networks, and propose a model which extends FOAF with Page Rank and Author Rank metrics, both implemented in Semantic Web Rule Language (SWRL), for gauging the reputation of authors. Preliminary results are demonstrated, showcasing also the huge potential of this ranking approach for adopting it on social networks in general, and by search engines in particular where our future work will focus.

Modeling co-authorship networks merely in FOAF, as is common with social networks, suffers the inability to capture semantics which are specific to collaboration schemes in the scientific community. For instance, the weight of the co-author relation which expresses the magnitude of that relation between two co-authors is subject to change dynamically as new publications are assigned to the co-authorship graph. They require mechanisms like rules in Semantic Web to calculate them. We introduce here a framework of (1) extending the FOAF ontology, and (2) implementing SWRL rules to construct weighted co-authorship networks which will contain metrics like exclusivity, frequency, or weight, as suggested in the literature. It makes it easy for the extended FOAF to integrate it with the native SWRL rules, and provide thus a uniform framework based solely on the Semantic Web for the representation and analysis of weighted co-authorship networks. An evaluation of our framework run on real data is provided.

Opting for link semantics in XML is almost like hyperlinks for HTML documents. XLink describes a standard way to add hyperlinks to an XML document. The current XPath technologies are restricted to follow ID / IDREF(S) links for intra-document navigation only. We investigate the Lightweight Directory Access Protocol (LDAP) that offers a rich collection of primitives to express links among distributed data collections in the network, and facilities to follow links when searching. In virtue of querying the underlying LDAP model by referrals, we developed an extended XPath processor that is capable of addressing links of any type (IDREF(S), XLink) embedded in XML data on the Web. Links may be inter-document, or even traverse across different local or remote servers. We describe the internal LDAP data representation and query model used by the processor for the storage and querying in XPath of XML documents based on links, and provide examples to illustrate them. We complement the discussion with experimental analyses that prove the efficiency of our query evaluation techniques. The latter confirms the relevance of our approach for applications that need to interact with interlinked XML document networks in an XPath-like fashion.
We investigate the Lightweight Directory Access Protocol (LDAP) that provides a powerful means to link distributed data collections into an entity searchable as a single collection. Besides the linking mechanism, LDAP offers a rich collection of modeling primitives required to express ontologies as a common searchable interface. Encouraged in addition by the fact that XML has become the de facto standard for information interchange on the Internet, LGACCESS, our global querying system, combines ontologies and XML into a unified LDAP-based framework to improve the power for accessing related XML data in the network. We describe a global query evaluation strategy based on expressive links among entities that are spread across different local or remote servers. Also, the way ontologies are annotated to hold such network-aware links along with semantic annotations is shown. Built on grounds of the standard and well-established LDAP technology instead of the technologies that are still in the process of adoption by the community, our system is an ideal candidate for applications that need to interact with semistructured databases at a global extent.
The increase in popularity of the Internet has lead to the proliferation of heterogeneous information systems that could be better utilized if they operated under a common query interface. The purpose of this paper is to describe the representation formalism of ontologies in an LDAP-based information integration system, and to point out the advantages of such an approach over traditional systems. The simplicity, coherence and uniformity of the LDAP model allows us to seamlessly integrate source data, schemata discrepancies, and semantic information under a common framework, that is, by design, able to reconcile integration and data processing issues.

With the increase in popularity of XML on the Internet, the requirements of database management systems have shifted from traditional transaction-based databases towards the kind of characteristics provided, by design, by the Lightweight Directory Access Protocol. At the same time, the design and use of a middleware to provide a common querying interface to XMl-based systems has become and increasingly relevant research problem, encouraged by the fact that XML has become the de facto standard for information interchange on the Internet. The purpose of this paper is to describe the formalisms for representing ontologies in LGAccess, our LDAP-based integration system, that is able to seamlessly integrate source data, schemata discrepancies, and semantic information under a common framework, thanks to the simplicity, coherence, and uniformity of the LDAP model. Due to a close resemblance between the XML model and LDAP, and to avoid dirtying sources or ontologies with semantic annotations necessary for integration, we introduce a middleware in our system to hold such annotations and support XML ontologies in their native representation without cumbersome transformations. Furthermore, instead of using the technologies that are still in the process of adoption by the community, the middleware is built on grounds of the standard and well-established LDAP technology.

Data integration systems share the idea that the Web as a huge repository of information sources made available online could be better utilized if they operated under a common query interface. Limiting the domain of querying to a predefined collection of terms and their relationships in form of ontologies as advised by the Semantic Web initiative makes the problem of integration easier.The purpose of this thesis is, therefore, to provide an ontology-based data integration system. Ontologies are out in a middleware of the system and are annotated to hold along with the semantic data, a kind of links which relate source data and allow to readily carry out sophisticated tasks for users when querying.Given the ubiquity of XML on the Web, the system is primarily dedicated to interact with semistructured databases. On the other hand, the use of Lightweight Directory Access Protocol (LDAP) to store a variety of information is also steadily gaining in popularity. Encouraged in addition by the fact that the LDAP model closely resembles that of XML, instead of using the XML technologies that are still in their infancies, we have chosen to use the well established LDAP technology in a middleware. Moreover, links that relate remote data make particular use of the LDAP's tight connection to network channels, enabling efficient query processing regardless of the breadth of data distribution. This way, a system on top of LDAP ontologies is built that allows a lightweight global access in XPath - the W3C XML core query language - to the content of XML data from anywhere in the network, keeping thereby the inner mixture of allocation of data, their schemata and semantics transparent to the user. XML data are assumed to be webbed, i.e. contain hyperlinks, in order to coexist as an ultimate data format in the World Wide Web. Generic algorithms for dereferencing linked XML data when querying with XPath are developed. The novelty thereby lies in the ability to handle links that may traverse across different local or remote servers as defined by XLink apart from the (internal) links dating from the time IDs and IDREF(S)s were used. Again, the rich LDAP repository of modeling primitives, this time regarding links, are deployed.

PhD ICT KES is an EU funded project within the Erasmus+ Key Action 2 program and led by the Linnaeus University, Sweden. The project is planned to be implemented within three years Novermber 15th 2019 to November 14th 2022.
University of Prishtina "Hasan Prishtina" (UP) is the only Higher Education Institution in Kosovo which has for years been providing PhD study programs in the area of ICT (PhD in Computer Engineering), and is currently in the phase of accreditation with a new PhD study program in the field. Moreover, UP is the only university in the country with tradition and accredited in all three levels of studies, bachelor, master and PhD in Computer Engineering, Faculty of Electrical and Computer Engineering.
The aim of the project is to engage in providing a set of recommendations for PhD studies suited to Kosovo needs, namely to develop a curricula model as well as guidelines, strategy and regulatory documentation on its implementation. Further, a "National PhD in ICT School" is to be established to facilitate the PhD studies in the field for Kosovo following the experiences from EU partner country universities participating in the project. Apart from academia, the Ministry of Education and Science, and the accreditation body in Kosovo are also involved in the project implementation to cover the policy issues related to the PhD studies, as well as business representatives to close the cycle of parties of interest to shape and support the studies in this field in PhDs.
The UP has the chance to benefit from the project by extending experiences in designing, developing and implementing curriculas at the PhD level in the field of ICT given the experience of the partner universities from the EU participating in the project, and through involving its staff and students in the project, but also by setting up new research infrastructure, as well as advancing its practices in support of PhD studies in the prospective field of ICT for Kosovo.
The project Consortium is constituted of:

"InWaterSense: Intelligent Wireless Sensor Networks for monitoring Surface Water Quality" is an EU funded project managed by the European Union Office in Kosova and implemented by University of Prishtina (Faculty of Electrical and Computer Engineering, and Faculty of Civil Engineering and Architecture), its young academic staff and students from both departments headed by Prof. Lule Ahmedi and Prof. Figene Ahmedi. A valuable contribution was given by international and local partners in the consortium: University of Duisburg-Essen (Germany), Vienna University of Technology (Austria), National Institute Tyndall (Ireland), Linnaeus University (Sweden), and Kosovo Hydro-Meteorological Institute. InWaterSense has achieved its aim in applying recent advanced practices stemming from ICT in water quality monitoring for healthy environment, and in strengthening Kosovo's capacity in research in national priority sectors of environment and ICT. A wireless sensor network for water quality monitoring is put in place and functional in Sitnica river.
Moreover, an intelligent software platform with a Web portal at the frontend has been implemented and providing in real-time and remotely raw water quality data of Sitinca at measurement points through sensors (inwatersense.uni-pr.edu/portal). For more on results of the project, visit the official project Website at inwatersense.uni-pr.edu, or download the project poster.
This is a project funded by the Erasmus+ programme of the European Union to support exchange of students and staff in the study area of ICTs between our two institutions:

The main contribution of the project is a novel system introduced for tourist tour planning based on social network analysis (SNA).
The system provides a travel plan to support end users once they have given some basic input in relation to their recommended Points of Interest (POI) to visit in the given destination. The user profile and his network of friends aids in recommending that user's destination POIs. Several models of interaction between the user and the system have been considered to adopt the best case scenarios. The linkage of the user and his network of friends in terms of the recommendations for the given destination has been considered to satisfy the user's taste as close as possible. The system is compliant with the existing e-Tourist solutions, but seeks to in addition gain from a typical behavior of a user on the Web 3.0 which acts within a social network rather than isolated in whatever online activity (alike the selection of the destination POIs).
The Internet as an enormous large heterogeneous information repository is witnessing the need to better utilize the available information by operating under a common query interface. Limiting the domain of integration to a predefined collection of terms and their relationships in form of ontologies makes the problem of integration easier. The purpose of this project is therefore to develop and implement an ontology-based information integration system. To provide support for data integration, we avoid "dirtying" sources or ontologies with semantic annotations necessary for integration and instead introduce a middleware in our system to hold such annotations.
The XML is on the way to prevail over all other existing data representation formats in the Web (HTML). Hence, to keep pace with current trends, we consider the system should without fail be XML-compatible. Due to a close resemblance between XML and LDAP models (hierarchical, simple, flexibile, extensibile, etc.) and to allow for a seamless integration of source data, schemata discrepancies and semantic information under a common framework, we put the LDAP standard technology in a middleware. Except to hold annotations, the LDAP middleware serves at the same time as a medium for a stable and efficient storage of ontologies in our system.
To survey, the whole paradigm discerns with two advantageous features:
It provides a light-weight global access to the content of XML data through a common ontology in XML from anywhere in the network, and
It performs a seamless integration of data, keeping the inner mixture of allocation of data, their schemas and semantics transparent to the user.
These highlights make our approach realistic for future trading architectures for information integration.

MSc. Kadri Sylejmani
took place in Linnaeus University to design the collaboration scheme in terms of mobility for staff and students, which followed later in the project as described above.
In this project, publication of open data of South East European University using Semantic Web and linked data technology is aimed. An ontology to describe university related information is developed. Then, the available structural and unstructured datasets of university are identified and accordingly mapped to open data. The aim of this repository is serving RDF triples around university information, thus offering convenience for data integration and information management. Finally, a human user interface to effectively and efficiently use and explore the dataset is developed and deployed.
A new master study program has been designed and implemented together with project partners, i.e., IT Carlow, Ireland, and University of La Rochelle, France.
An e-Learning infrastructure has been designed and implemented to support e-lectures, i.e., teaching in distance.
