Research on an Improved Algorithm of Professional Information Retrieval System

As the Internet develops faster and faster, resources are becoming more and more abundant. It is more and more difficult for people to retrieve the information they need from a large number of resources. The professional information retrieval system came into being. However, the current system can not retrieve resources to meet the user's requirements. In this paper, I propose a new TF-IDF information retrieval improved algorithm, which makes the resources retrieved by the information retrieval system more professional and presents people with a more accurate result. The experimental results show that the TF-IDF improved algorithm can achieve higher precision P and Recall R.
