建设法规政策知识库中后控词表检索设计

编制后控词表是实现智能查询的重要环节.针对建立"智能化建设法规政策知识库",重点研究通过后控词表实现智能化查询的方法.针对自然语言查询涉及政策法规和案例两类查询结果,从而设计了包含有两个主题词表,共6个词表的后控词表模式,分析词表关联关系,说明词表的词汇集合关系,并给出了基于此模式的智能查询算法,对大型文献智能知识库系统开发中后控词表的编制具有一定借鉴意义.

Post controlled vocabulary design based on knowledge database of building regulations and policies

Designing a post controlled vocabulary is a important step for realizing intelligent querying.For building "the knowledge database of intelligentized building regulations and policies",the method of realizing intelligent querying based on post controlled vo-cabulary is researched.There are two types of results,regulations and policies and examples,would be get according to user's querying with nature language.A post controlled vocabulary model with six vocabularies is designed,two key-words vocabularies are included,and the relation among the vocabularies is analyzed,the relations between key words sets and puts forward the intelligent querying based on the model is given.Some extent reference meaning for design the post controlled vocabulary in the development of huge literature in-telligentized knowledge database is possessed.
