  1. 1. Querying Data Providing Web Services

    Author : Manivasakan Sabesan; Tore Risch; Roberto V. Zicari; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; views of web service operations; web service queries; adaptive parallelization; query optimization; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Web services are often used for search computing where data is retrieved from servers providing information of different kinds. Such data providing web services return a set of objects for a given set of parameters without any side effects. READ MORE

  2. 2. Semantic Web Queries over Scientific Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andrej Andrejev; Tore Risch; Kjell Orsborn; Ruslan Fomkin; Gerhard Weikum; [2016]
    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.

  3. 3. Querying mediated web services

    University dissertation from Uppsala University

    Author : Manivasakan Sabesan; Tore Risch; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Web services provide a framework for data interchange between applications by incorporating standards such as XMLSchema, WSDL, SOAP, HTTP etc. They define operations to be invoked over a network to perform the actions. These operations are described publicly in a WSDL document with the data types of their argument and result. READ MORE

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

    University dissertation from Uppsala University

    Author : Silvia Stefanova; Tore Risch; Stefan Decker; []
    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.

  5. 5. Main-Memory Query Processing Utilizing External Indexes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Thanh Truong; Tore Risch; Martin Kersten; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Database indexing; query processing; index structures; main-memory; index validation; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Many applications require storage and indexing of new kinds of data in main-memory, e.g. color histograms, textures, shape features, gene sequences, sensor readings, or financial time series. READ MORE
