1. 6. 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 :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.

4. 8. Towards an Ontology Design Pattern Quality Model

   Författare :Karl Hammar; Kurt Sandkuhl; Henrik Eriksson; Vladimir Tarasov; Eva Blomqvist; Arianit Kurti; Jönköping University; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology; OWL; Ontology Design Pattern; Semantic Web; Quality Model;

   Sammanfattning : The use of semantic technologies and Semantic Web ontologies in particular have enabled many recent developments in information integration, search engines, and reasoning over formalised knowledge. Ontology Design Patterns have been proposed to be useful in simplifying the development of Semantic Web ontologies by codifying and reusing modelling best practices. LÄS MER

5. 9. Completing the Is-a Structure in Description Logics Ontologies

   Författare :Zlatan Dragisic; Patrick Lambrix; Fang Wei-Kleiner; Guilin Qi; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Knowledge representation; ontology; ontology engineering; ontology debugging; description logics;

   Sammanfattning : The World Wide Web contains large amounts of data and in most cases this data is without any explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. LÄS MER

7. 10. Content Ontology Design Patterns: Qualities, Methods, and Tools

   Författare :Karl Hammar; Henrik Eriksson; Vladimir Tarasov; Eva Blomqvist; Harald Sack; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology; Ontology Design Pattern; Quality Model; eXtreme Design; XDP; WebProtégé;

   Sammanfattning : 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. LÄS MER
