本体技术可以有效的解决各种异构信息的转换和集成问题,但是现阶段人们却缺乏有效的自动本体构建方法.本文根据现有的图情专业学术文献数据库,提出一种利用引文关键词共现技术的领域本体自动构建方法.该方法利用引文分析思想来计算文献的学术价值,并以此来计算文献和引用文献的词语共现对权重值,完成了本体结构中层次概念联系的表达和设计,同时还利用基于加权词语共现对序列相似度的算法实现了同义概念联系的抽取.最后,本文就相关实验及其结论做了详细的说明.%Ontology can be used to resolve many problems in exchange and integrity of heterogeneous informationefficiently. However, we still have no effective methods to construct ontology automatically. Using academic documents of library and information science, this paper proposes an automatic construction method of domain ontology based on weighted co-occurrence of citation keywords. This method begins with computation the weight value of co-occurred term pair between current paper and citation paper with academic weight of document based on citation analysis. And from this point, the hierarchical concept relationships in ontology structure can be expressed and designed. We also implement the exaction of synonymous concept relationships based on the similarity algorithm of weighted co-occurred term pair sequence. Finally some related experiments and conclusion are introduced in details.
