Abstract

The invention provides a text similarity calculation method and system, a data query system, a computer product and a computer readable storage medium. The text similarity calculation method comprisesthe steps that at least a first text and a second text are acquired; the first text and the second text are mapped into vectors; similar parts and different parts of the first text and the second text are calculated; and the similar parts and the different parts are utilized to calculate the similarity between the first text and the second text. According to the text similarity calculation methodand system, the influence of word semantic similarity and difference on the text similarity is at least partially considered, the semantic similarity between the texts can be calculated from finer granularity, therefore, text matching precision is improved, and high-precision retrieval or query and the like are realized.

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.) ...
