  1. 1. Completion of Ontologies and Ontology Networks

    Författare :Zlatan Dragisic; Patrick Lambrix; Nahid Shahmehri; Marco Kuhlmann; Fang Wei-Kleiner; Erhard Rahm; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; knowledge representation; ontology; ontology engineering; ontology debugging; ontology completion; ontology matching; description logics;

    Sammanfattning : 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. LÄS MER

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

    Författare :Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Eero Hyvönen; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology; ontology engineering; ontology alignment; ontology debugging;

    Sammanfattning : 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.

  3. 3. Fostering User Involvement in Ontology Alignment and Alignment Evaluation

    Författare :Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Fabien Gandon; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Knowledge representation; ontology; ontology engineering; ontology debugging; ontology matching; ontology matching evaluation; user interfaces; human-computer interaction; large and high-resolution displays;

    Sammanfattning : The abundance of data at our disposal empowers data-driven applications and decision making. The knowledge captured in the data, however, has not been utilized to full potential, as it is only accessible to human interpretation and data are distributed in heterogeneous repositories. LÄS MER

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

    Författare :Qiang Liu; Patrick Lambrix; Nahid Shahmehri; Henrik Eriksson; He Tan; Heiner Stuckenschmidt; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Ontology; Ontology Engineering; Ontology Alignment; Ontology Debugging; Information technology; Informationsteknik;

    Sammanfattning : 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. LÄS MER

  5. 5. Cross-language Ontology Learning : Incorporating and Exploiting Cross-language Data in the Ontology Learning Process

    Författare :Hans Hjelm; Martin Volk; Joakim Nivre; Philipp Cimiano; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ontologies; Ontology learning; Distributional semantics; Knowledge acquisition; Text mining; Computational linguistics; Datorlingvistik; datorlingvistik; Computational Linguistics;

    Sammanfattning : An ontology is a knowledge-representation structure, where words, terms or concepts are defined by their mutual hierarchical relations. Ontologies are becoming ever more prevalent in the world of natural language processing, where we currently see a tendency towards using semantics for solving a variety of tasks, particularly tasks related to information access.
