2. 1. Scalable Preservation, Reconstruction, and Querying of Databases in terms of Semantic Web Representations

   Author : Silvia Stefanova; Tore Risch; Stefan Decker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; RDF; RDFS; RDF view; SPARQL; SPARQL query processing; rewrite optimization; Topic Maps; querying of RDF views; archive relational databases; reconstruct archived databases; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : This Thesis addresses how Semantic Web representations, in particular RDF, can enable flexible and scalable preservation, recreation, and querying of databases.An approach has been developed for selective scalable long-term archival of relational databases (RDBs) as RDF, implemented in the SAQ (Semantic Archive and Query) system.

4. 2. Semantic Web Queries over Scientific Data

   Author : Andrej Andrejev; Tore Risch; Kjell Orsborn; Ruslan Fomkin; Gerhard Weikum; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

   Abstract : The pharmaceutical industry is facing a research and development productivity crisis. At the same time we have access to more biological data than ever from recent advancements in high-throughput experimental methods. READ MORE

6. 4. Querying RDF Schema Views of Relational Databases

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

   Abstract : 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. READ MORE

7. 5. Diversified Retrieval of Spatial Data with Context

   Author : Georgios Kalamatianos; Georgios J Fakas; Aristides Gionis; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proportionality; Diversity; Keyword Search; Spatial Data; Ranking; Computer Science; Datavetenskap;

   Abstract : The abundance and ubiquity of spatial datasets necessitates their effective and efficient retrieval. For instance, on the web, there are datasets with GIS objects or POIs (e.g. Spatialhadoop datasets), datasets with geo-tagged photographs (e. READ MORE
