一种多视角新闻信息快速检索方法
Method of fast news information retrieval from multiple perspective
摘要
Abstract
Information retrieval has always been an important field of data mining research and an important mean of intelligence gathering.If the manual search method is used to retrieve information in the database,the retrieval efficiency is low.Therefore,a method of fast news information retrieval from multiple perspectives is proposed with the application background of news information collection and the purpose of improving the efficiency of the information retrieval.In this method,the multi-perspective news description information that users need to retrieve is used as the retrieval basis,and the keyword weight segmentation method is used to process multi-perspective news description information to build vocabulary vectors.The retrieval results of vocabulary vectors in the news information database are used as the basis to build vocabulary retrieval vectors.The vector similarity calculation model is used as the information screening rule to rapidly retrieve and screen out the news information that users need to collect in the news information database.The design model of the proposed method,the implementation strategy for key technologies involved in the method,data processing flow,and the comparative analysis of experiments are provided.The experimental results show that,according to multi-perspective news description information specified by users,this method can quickly and efficiently retrieve and screen out news article information that meets users'needs in the news information database.关键词
