Problems solved by technology

[0010] However, this method has two disadvantages: firstly, a vocabulary with more synonyms will have a greater impact on the results; secondly, it does not solve the problem of polysemy
[0014] But because this method relies on the database of the search engine, the calculated results are often unstable

Abstract

The invention discloses a calculating method of text similarity degree and vocabulary meaning similarity degree and system and application system, which comprises the following steps: basing on vocabulary data bank; proceeding initialize; calculating; getting initial vocabulary meaning similarity degree among vocabulary in the vocabulary data bank; basing on the initial vocabulary meaning similarity degree; calculating initial semantic similarity degree among text; iterating semantic similarity degree among each text and vocabulary meaning similarity degree among vocabulary till constriction; constructuring final vocabulary meaning similar matrix with final vocabulary similarity degree; transforming the text vocabulary frequency vector of the initial text to the new text vocabulary text vocabulary frequency vector; calculating text similarity degree in the text collection. This invention can improve related property of current text especially about short text.

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...
