为克服依赖常识人工归纳总结的局限性,采用定性和定量相结合的方式,自动构建空间关系词汇与地理要素类型的语义约束关系。首先,以《中国大百科全书(地理版)》空间关系标注语料库为基础数据,采用Overlap语义相关度计量方法,挖掘空间关系词汇与地理要素类型约束关系的先验知识;然后以地理要素分类体系提供的概念语义相关性对先验知识进行扩展;最后采用本体工具Protégé建立相关知识库。
In order to overcome the limitation of artificial induction based on common sense, the semantic constraint relation between spatial relation vocabulary and geographical feature type is automatically constructed by combining qualitative and quantitative methods. Firstly, based on the spatial annotation corpus of “Encyclopedia of China (Geographical Edition)”, the overlap semantic relevancy measurement method was used to mine the prior knowledge of the spatial relationships between the lexical elements and the geography factor types. Then, Provides the semantic relevance of the concept to expand the prior knowledge; Finally, using the ontology tool Protégé to build the relevant knowledge base.
