Abstract: In order to make it easier for users to search for information resources, a recommendation system for scientific and technological information resources is proposed based on the analysis of user needs.  Through collecting the characteristics of information resources required by users, extracting the common parameters of the characteristics, and classifying according to different parameter ranges, in order to ensure the accuracy of the classification of resource characteristics, the classification algorithm of scientific and technological information resources is optimized, and the classification recommendation system of scientific and technological information resources is designed according to the calculation results, so as to realize the goal of recommending resources according to different user requirements. Finally, the experiment proves that the scientific and technological information resources recommendation system based on user demand analysis can better provide the required information resources for users and facilitate resource searching.
