Xiaobing Zhao · Zhongwen xinxi xuebao · 2011
Semantic ontology is a formal,explicit specification of a shared conceptualization,which provides a shared vocabulary used to model a domain—that is,the type of objects and/or concepts that exist,and their properties and relations.Hyponymy pattern is a basic semantic relationship between concepts,which is used to concepts acquisition in an ontology automatically.In this paper,hyponymy pattern is represented as a pair of a meaning frame defining the necessary information extraction in Tibetan language.Then the concept acquisition algorithm and the method of how to get pattern-match sentences are presented.The research of hyponymy relationship pattern can assist concept enrichment in ontology,which can reduce the cost during the ontology engineering process.
