  1. 1. Completion of Ontologies and Ontology Networks

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Zlatan Dragisic; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; knowledge representation; ontology; ontology engineering; ontology debugging; ontology completion; ontology matching; description logics;

    Abstract : The World Wide Web contains large amounts of data, and in most cases this data has no explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. A step towards a more structured World Wide Web is the Semantic Web, which aims at introducing semantics to data on the World Wide Web. READ MORE

  2. 2. Integration of Ontology Alignment and Ontology Debugging for Taxonomy Networks

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Valentina Ivanova; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology; ontology engineering; ontology alignment; ontology debugging;

    Abstract : Semantically-enabled applications, such as ontology-based search and data integration, take into account the semantics of the input data in their algorithms. Such applications often use ontologies, which model the application domains in question, as well as alignments, which provide information about the relationships between the terms in the different ontologies.

  4. 4. Content Ontology Design Patterns: Qualities, Methods, and Tools

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Karl Hammar; Linköpings universitet.; Linköpings universitet.; Högskolan i Jönköping.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontology; Ontology Design Pattern; Quality Model; eXtreme Design; XDP; WebProtégé;

    Abstract : Ontologies are formal knowledge models that describe concepts and relationships and enable data integration, information search, and reasoning. Ontology Design Patterns (ODPs) are reusable solutions intended to simplify ontology development and support the use of semantic technologies by ontology engineers. READ MORE

  5. 5. Dealing with Missing Mappings and Structure in a Network of Ontologies

    University dissertation from Linköping University : Linköping University Electronic Press

    Author : Qiang Liu; Linköpings universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontology; Ontology Engineering; Ontology Alignment; Ontology Debugging; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik;

    Abstract : With the popularity of the World Wide Web, a large amount of data is generated and made available through the Internet everyday. To integrate and query this huge amount of heterogeneous data, the vision of Semantic Web has been recognized as a possible solution. One key technology for the Semantic Web is ontologies. READ MORE
