基于领域本体科学效应知识语义检索的研究

当前传统的信息检索技术并不能准确的捕获用户的信息需求，基于本体的方法虽然考虑到语义搜索的复杂性但是却迫使用户使用一个十分难以掌握的查询语法．通过对用户查询习惯和查询短语的分析，我们发现查询短语通常为简单的动宾结构短语．针对化学领域科学效应知识和用户的查询习惯的特点，给出了一种从自然语言查询到本体知识映射的语义检索的方法．

Reseach of Semantic Retrieval of Science Effect Based on Domain Ontology

Current information retrieval （IR） approaches do not formally capture the explicit meaning ot a query. Ontology-based approaches allow for sophisticated semantic search but impose a query syntax more difficult to handle. Through the analysis of user＇s query habits and query phrase, we found that a simple query phrase usually verb-object phrase. For the field of chemistry knowledge and scientific effects of the characteristics of the user＇s query habits, we present an approach for translating natural language queries to ontology knowledge.
