Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] In one embodiment, such as figure 1 As shown, a method of synonym mining is provided, and the application of the method to computer devices such as clients or servers is used as an example for illustration, including the following steps:

[0027] 101. Obtain a target sentence, and search the target sentence through a full-text search engine to obtain at least one similar sentence.

[0028] Among them, a full-text search engine refers to a search engine that retrieves relevant records that match user query conditions from a database built from information extracted from various websites on the Internet, and then returns the results to the user in a certain order. In this embodiment, the datab...

Abstract

The invention discloses a synonym mining method and device, a storage medium and computer equipment, and relates to the field of big data analysis. The method comprises the steps of obtaining a targetstatement, searching the target statement for through a full-text search engine, obtaining a first similar statement of the target statement, and the target statement and the first similar statementcomprise at least one same word; creating a similar sentence pair according to the target sentence and the first similar sentence; performing similarity scoring on the similar sentence pairs, obtaining synonym sentence pairs according to the similarity scores, and performing word alignment extraction on the synonym sentence pairs to obtain synonym pairs; and inputting the synonym pairs and the target statement into the full-text search engine for iterative search and iterative extraction to obtain a plurality of synonym sentence pairs and a plurality of synonym pairs. According to the method,the mining quantity and mining quality of synonyms and synonym sentences can be remarkably improved, and the synonym mining limitation and technical implementation difficulty are reduced.

Description

technical field [0001] The invention relates to the field of big data analysis, in particular to a synonym mining method, device, storage medium and computer equipment. Background technique [0002] Synonym mining is a relatively basic problem in natural language processing. Synonyms can be used in various fields such as robot dialogue generation, machine translation, and sentence rewriting. There are mainly three existing methods for mining synonyms, which are the extraction method from structured data, the click log mining method and the word2vec similarity matching method. [0003] Among them, the method of structured extraction refers to using Baidu Encyclopedia, Kingsoft PowerWord and other dictionaries to find characteristic words such as "alias" and "also known as" to extract synonyms. This method is relatively limited in extracting synonyms, and the extracted synonyms are some general fields. Synonyms; while the click log mining method refers to the use of user quer...
