1. 11. 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

   Sammanfattning : The contemporary computers typically consist of multiple computing cores with high compute power. Such computers make excellent concurrent asynchronous shared memory system. LÄS MER

4. 13. 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

5. 14. Semantic Web Queries over Scientific Data

   Författare :Andrej Andrejev; Tore Risch; Kjell Orsborn; Ruslan Fomkin; Gerhard Weikum; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RDF; SPARQL; Arrays; Query optimization; Second-order functions; Scientific workflows; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Sammanfattning : Semantic Web and Linked Open Data provide a potential platform for interoperability of scientific data, offering a flexible model for providing machine-readable and queryable metadata. However, RDF and SPARQL gained limited adoption within the scientific community, mainly due to the lack of support for managing massive numeric data, along with certain other important features – such as extensibility with user-defined functions, query modularity, and integration with existing environments and workflows.

7. 15. Gamla mönster i nya former? Tre studier om specialpedagogik i teori och praktik

   Författare :Reidun Carlsson; Claes Nilholm; Tomas Englund; Guy Karnung; Anna-Lena Tvingstedt; Örebro universitet; []
   Nyckelord :special educational needs; democracy; inclusion; language preschool; remedial plans; governance; Education; Pedagogik;

   Sammanfattning : The overall aim of the research presented here is to examine challenges in the special needs support tradition and the consequences of these challenges with the aim of increasing knowledge regarding the opportunities and constraints that are created as partof the support. In addition, the overarching study aims to highlight issues of democracyand inclusion in the social practices that are focused here and in what manner theseemerge and are framed. LÄS MER
