Description

technical field

[0001] The present invention relates to the field of computer text information processing, in particular to a text similarity calculation method and system between texts, a word meaning similarity calculation method and system between words in a text, and an application system using the text similarity calculation system . Background technique

[0002] With the popularization of computers for various natural language processing applications such as text information, people need an effective and accurate method to calculate the text similarity between two texts or sentences, that is, the computer text similarity calculation method. In particular, the calculation of short text similarity plays a very important role, and its application can greatly improve the accuracy of the system's automatic question answering.

[0003] The calculation method of similarity between texts (especially short texts) is playing an increasingly important role in computer text-relat...
