基于规则推理的语义检索若干关键技术研究
Research on Critical Technologies of Semantic Retrieval Based on Rule Reasoning
摘要
Abstract
For some complex specified domain retrieval requirements,many researches use semantic related technologies to resolve such problems.In terms of rule inference,it always leverages the inference algorithm of Semantic Web directly.However,the efficiency is not good.On the respects of searching results ordering,the ordering algorithm for search engine,which is based on keywords,is not suitable for ranking on search results generated by semantic retrieving.Focusing on the above issues,this paper proposes a semantic rule modeling method,and gives a new rule reasoning algorithm based on closed world assumption backwards reasoning chain to get higher inference efficiency compared to most semantic inference engines.Moreover,this paper proposes a new ordering algorithm based on feature similarity.Taking advantage of the above methods this paper describes,the search engine-Material Hub has been built up.Experiments show this semantic search engine improves the searching precision rate,recall rate,and rational responding time.So far,this system has been applied in industry.关键词
