2000年以来我国信息检索模型研究综述

摘要 信息检索模型是用户信息检索快、全、准的重要框架和方法,随着信息技术的快速发展,用户对信息检索的要求越来越高。为梳理信息检索模型研究进展,借助CiteSpace对2000-2018年CNKI数据库中信息检索模型研究的相关文献进行了分析,发现文献量呈现快速增加又逐渐回落的趋势,研究文献主要集中在部分机构,且机构间合作较少,作者也呈现“总体分散、局部集中”的特点,研究主题从应用领域向技术研究过渡,主要包括基于本体的信息检索模型研究、基于贝叶斯网络的信息检索模型研究、数字图书馆信息检索模型研究等热点主题。 Information retrieval model is an important framework and method for users to search information quickly,completely and accurately. With the rapid development of information technology,users’ requirements for information retrieval are getting higher and higher. In order to sort out the research progress of information retrieval model,CiteSpace is used to analyze the relevant literature on information retrieval model in CNKI database from 2000 to 2018. It is found that the amount of literature is increasing rapidly and declining gradually. The research literature is mainly concentrated some institutions,and there is less inter-agency cooperation. The author also presents the characteristics of"overall decentralization and local concentration". The transition from application field to technology research mainly includes the research of ontology-based information retrieval model,Bayesian network-based information retrieval model,and the research of information retrieval model in digital libraries.
