摘要
语义本体是共享概念模型显示的形式化规范说明,其目标是将杂乱无章的信息源转变为有序易用的知识源。目前语义本体还主要依赖于手工创建模式。上下位关系是一种基本的语义关系,常用于语义本体中概念的自动获取和验证。该文首先描述了藏文语义本体的创建方法,进而给出了藏文中的上下位关系模式以及模式匹配算法。上下位关系的模式可以辅助进行概念扩充,也可以作为建立和维护本体的辅助工具,这在一定程度上降低了创建和维护本体的成本。
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.
