摘　　要：为了获得更理想的图书馆信息检索结果,提出了基于人工智能技术的图书馆信息检索模型。将查询请求发送至信息检索模块,并通过标准化、规划化创建本体,选取贝叶斯网络作为推理机,通过语义逻辑推理、抽取、查询处理用户所输入请求,利用概率估计结果获取逻辑表达式实施推理与检索,从知识库中寻找理想结果,根据排序检索结果得到图书馆信息检索结果,测试结果表明,将测试词语输入该模型后所获取文档的相关性高于0.96,且具有较高的查全率、查准率。In order to obtain more ideal results of library information retrieval,a library information retrieval model based on artificial intelligence technology is put.The query request is sent to the information retrieval module,and ontology is created through standardization and planning.Bayesian network is selected as the inference engine,and the user’s input request is processed through semantic logic reasoning,extraction and query.The logical expression is obtained by probability estimation result to implement reasoning and retrieval,and the ideal result is found from the knowledge base according to the results of library information retrieval,the test results show that the relevance of the documents obtained by inputting test words into the model is higher than 0.96,and has high recall and precision.
