The disclosure provides a text similarity calculation method and system, a data query system, a computer product, and a computer-readable storage medium. The method for calculating the text similarity includes: acquiring at least a first text and a second text; mapping the first text and the second text into vectors; calculating similarities and differences between the first text and the second text part; calculating the similarity between the first text and the second text by using the similar part and the difference part. According to the calculation method and system of text similarity provided by the present disclosure, the impact of semantic similarity and difference of words on text similarity is at least partially considered, and the semantic similarity between texts can be calculated from a finer granularity, and then Improve the accuracy of text matching, realize high-precision retrieval or query, etc.
Description
technical field [0001] The present application relates to the field of data processing, in particular to a method and system for calculating text similarity, a data query system, computer products and computer-readable storage media. Background technique [0002] The rapid development of the Internet and the advent of the era of big data provide a basis for people to effectively obtain various types of information. At present, people are used to obtaining all kinds of information through the Internet. For example, in the medical field, medical staff can search for required documents, books, or related web pages by inputting keywords. For patients, they can meet their own information needs by checking the community Q&A on the medical website. The basic process of the information service system is based on the query or question input by the user, and returns the content most relevant to the query or question from the data (document set, question set or knowledge base, etc.) ...
