Design of Information System Function Check Algorithm Based on Cosine Theorem

Abstract

In order to solve the problem of duplicate function between the feasibility study content of the company's information project preparation and the built system, an information system function check algorithm based on cosine theorem is designed. In view of the three major problems in the company's digital reform and construction, namely, "difficulty in coordination", "difficulty in project approval" and "difficulty in construction management and control", first of all, the overall implementation architecture of the information system inspection model is planned and designed according to actual business needs. Secondly, with the support of word segmentation technology, TF-IDF weighted word frequency sorting and similarity calculation, the five steps of realizing duplicate checking algorithm are constructed; finally, the algorithm is simulated and tested. Experiments have proved that this algorithm is feasible, accurate and applicable. It can better identify and quantify duplicate functions for all new projects of the company, and improve the efficiency and quality of rechecking work.
