In order to improve customer satisfaction, massive Web multi-attribute data queries are conducted by integrating user interests. Based on the attributes of the data, obtain the topic vector of Web multi-attribute data, and consider the forgetting factor to dynamically manage user interests, in order to more accurately reflect the current interests of users. On this basis, cosine similarity is used to calculate the similarity between Web multi-attribute data feature vectors and user interest topic vectors, and Borda counting method is used to integrate the initialization query list and personalized query list to obtain the final query list that comprehensively considers user interests, achieving a personalized data query experience. The experimental results show that the algorithm can achieve Web multi-attribute data queries and has the ability to handle ambiguous queries. And as the number of queries increases, user satisfaction approaches 100%. This article demonstrates that the algorithm can further understand the needs of users based on their query content, and provide users with more accurate query results.
