Problems solved by technology
The disadvantages of this method are: 1. It only considers the relevant information and characteristics of the user, but does not consider the change of the user's demand tendency brought about by the situation; 2. The technology map it uses is more like a kind of subjective experience data. Recommendations often have subjective influence and lack of objectivity

The invention discloses a scientific and technological resource recommendation method and system based on user portraits and situations. The method comprises the steps: collecting scientific and technological resource data, and cleaning and importing thescientific and technological resource data into an information database; integrating and standardizing the scientific and technological resource data imported into the information database; generating a recommendation list based on the purchase preference of the user for the science and technology resources and the situational score; and performing visualization processing on the scientific and technological resource recommendation list, and presenting the processed list to a user. According to the method and system, the user preferences hidden behind the user behavior data are fully mined, and the problems of overall purchase preference and scenario score prediction of the user are solved. Moreover, through weighted synthesis of two recommendation bases of purchase preference and situational scoring of the scientific and technological resources by the user, the problems of data sparsity and cold start in the scientific and technological resource recommendation system are solved, the performance of the scientific and technological resource recommendation system is improved, and the accuracy and objectivity of scientific and technological resource recommendation are improved.
Description
technical field [0001] The invention relates to a method for recommending scientific and technological resources based on user portraits and situations, and also relates to a corresponding recommending system for scientific and technological resources, belonging to the technical field of data processing of scientific and technological resources. Background technique [0002] Scientific and technological resources refer to the resource collection of human, material, financial, organization, management, information and other software and hardware elements engaged in scientific and technological activities, including instruments and equipment, research and experiment bases, scientific and technological talents, scientific and technological literature, scientific data, scientific and technological achievements, enterprise resources, etc. . [0003] In the knowledge era, scientific and technological resources are becoming more and more important in the development of the national...
