Abstract

The embodiment of the invention provides a text similarity calculation method and device. According to the embodiment of the invention, the method comprises: respectively determining a label keyword set and a non-label keyword set in a first text and a second text; determining a first similarity between a first label keyword set of a first text and a second label keyword set of a second text basedon a preset hierarchical tree used for representing an association relationship between keywords; determining a second similarity between the first non-label keyword set of the first text and the second non-label keyword set of the second text based on a preset semantic model; and finally, determining the text similarity between the first text and the second text according to the first similarityand the second similarity, and calculating the similarity between the texts by extracting keywords in the texts and utilizing the keywords, thereby achieving the purpose of quickly calculating the text similarity.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a text similarity calculation method and device. Background technique [0002] With the rapid development of Internet information technology, people can easily upload or download shared document information, and this sharing mode will directly lead to the existence of massive documents. Currently, sentence matching or keyword matching is mainly used to determine the similarity between texts. However, due to the complex and changeable grammatical structure of Chinese sentences, the heterogeneity of semantic context and other factors, the calculation of similarity between Chinese sentences has been increased. Difficulty, so the existing technology cannot quickly and accurately obtain similar documents from batch documents. [0003] In view of this situation, a large number of solutions have been proposed in the prior art, which are mainly divided into: prior art 1...
