1. 16. Supporting loose forms of collaboration : Using Linked Data to realize an architecture for collective knowledge construction

   Författare :Hannes Ebner; Marko Turpeinen; Ambjörn Naeve; John Breslin; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linked data; collaboration; information model; contribution; application architecture; web application; web standards; www; open world assumption; Informations- och kommunikationsteknik; Information and Communication Technology; Media Technology; Medieteknik; Computer Science; Datalogi;

   Sammanfattning : This thesis is driven by the motivation to explore a way of working collaboratively that closely reflects the World Wide Web (WWW), more specifically the potential of the Web architecture built on Semantic Web technologies and Linked Data. The goal is to describe a generic approach and architecture that satisfies the needs for loose collaboration and collective knowledge construction as exemplified by the applications described in this thesis.

3. 17. Towards Semantically Enabled Complex Event Processing

   Författare :Robin Keskisärkkä; Eva Blomqvist; Henrik Eriksson; Daniele Dell'Aglio; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semantic Web; RDF stream processing; Complex Event Processing; Event modeling; Query abstraction;

   Sammanfattning : The Semantic Web provides a framework for semantically annotating data on the web, and the Resource Description Framework (RDF) supports the integration of structured data represented in heterogeneous formats. Traditionally, the Semantic Web has focused primarily on more or less static data, but information on the web today is becoming increasingly dynamic. LÄS MER

4. 18. Go the Extra Mile for Accountability : Privacy Protection Measures for Emerging Information Management Systems

   Författare :Jenni Reuben; Simone Fischer-Hübner; Sabrina Kirrane; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accountability; Privacy By Design PdD ; privacy risks; Privacy Impact Assessment PIA ; audits; privacy compliance; access control; differential privacy; graphs; edge-labeled graphs; Semantic Web; Computer Science; Datavetenskap;

   Sammanfattning : The thesis considers a systematic approach to design and develop techniques for preventing personal data exposure in next generation information management systems with the aim of ensuring accountability of data controllers (entities that process personal data).With a rapid growth in the communication technologies, heterogenous computing environments that offer cost-effective data processing alternatives are emerging.

5. 19. Querying RDF Schema Views of Relational Databases

   Författare :Johan Petrini; Tore Risch; Larry Kerschberg; Uppsala universitet; []
   Nyckelord :query processing; partial evaluation; rdf; rdf schema; view; relational databases; semantic web;

   Sammanfattning : The amount of data found on the web today and its lack of semantics makes it increasingly harder to retrieve a particular piece of information. With the Resource Description Framework (RDF) every piece of information can be annotated with properties describing its semantics. LÄS MER

7. 20. Methods to Improve and Evaluate Spatial Data Infrastructures

   Författare :Ara Toomanian; Centrum för geografiska informationssystem (GIS-centrum); []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial data infrastructure; evaluation; balanced scorecard; geoportals; clearinghouse; web cartography; expert system; web services;

   Sammanfattning : This thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI.
