The chemical industry is developing rapidly at home and abroad.The chemical industry is one of the pillar industries of the national economy,and its development is closely related to the national economic situation.At the same time,e-commerce platform is also developing rapidly.Recommendation system is widely used in e-commerce platform.However,the traditional recommendation algorithm is not completely suitable for chemical technology recommendation,which has the problem of low accuracy and can not meet the needs of users,and the chemical technology trading platform is a big vacancy in the current market.Under this background,this paper proposes an improved recommendation algorithm to make it more suitable for chemical technology recommendation.This paper first describes the research background,significance,research status at home and abroad and the current situation of recommendation system,and describes the theoretical basis and algorithm process of common recommendation algorithm in detail,analyzes its advantages and disadvantages,and expounds the evaluation index of recommendation algorithm.The data set of this paper selects the data of one month from techno-e.com,including more than 60000 interested and comments of 2914 users on 4330 chemical technologies.Aiming at the problems of cold start and sparse matrix in traditional recommendation algorithm,an improved recommendation algorithm based on similarity calculation formula is proposed.Firstly,the user Chemical Technology matrix is established,and the adjustment factor is introduced when calculating the similarity between chemical technologies.Finally,the recommendation result is obtained.Finally,the algorithm proposed in this paper is compared with other algorithms,and the experimental results show that the method proposed in this paper is feasible The algorithm is more suitable for the recommendation of chemical technology,and alleviates the problem of cold start to a certain extent.The chemical technology trading platform uses SSM framework,B/S network architecture,front-end and back-end separation,Mysql database and other technologies,and integrates the proposed recommendation algorithm to realize a more complete chemical technology trading platform.According to the functional requirements of the system,the chemical technology recommendation module,technology release module,purchase module,user center and user management module,and chemical technology management module have been completed.Perform a comprehensive test on the completed system.According to the analysis of the test results,the system can fully display the functions required by the user and obtain good test results.
