基于互联网的海量信息检索系统检索策略模式研究

Research on the Retrieval Strategy and Model of the Massive Information Retrieval System Based on the Internet

在检索系统对基于互联网的海量信息进行检索的过程中,检索效率很大程度上取决于检索策略的质量。为提高检索策略的正确性,本文根据信息逻辑检索的基本原理,并参照DIALOG系统,提出了检索需求的主题分析法则,并在此基础上建立了检索策略优化模型。同时,还给出了此模型在操作执行过程中的组配机制。

In the process of retrieving the massive information based on the Intemet, the retrieval efficiency of the retrieval system depends largely on the quality of the retrieval strategy. In order to improve the accuracy of the retrieval strategy, this article, based on the basic principle of information logic searching and referring to the DIA- LOG system, proposes the principle of thematic analysis of retrieval requirement, and based on this, constructs an optimized model of retrieval strategy. The article also gives the combination mechanism in the operating process of this model.
