基于语义的应急预案库检索本体表示研究

Emergency Plans Library Based on Semantic Ontology Representation of Search

针对传统关键词检索的种种弊端,引入本体概念,并通过建立领域检索的本体,对查询关键词进行语义扩展。经扩展后的关键词簇,从另一种意义上来说让检索系统具备了对语义理解的能力,使查询更加面向可能发生的具体应急事件。本研究更加人性化,同时改善了基于关键词的搜索体验。

For the drawback of keyword search,the concept of ontology is introduced and retrieve the body through the establishment of areas to expand on the semantic query keywords.The expanded keyword clusters from another sense have the semantic retrieval system understanding,and it makes the query more likely to occur for specific emergencies,more humane,while improving the search experience based on keywords.
