Embodiment Construction

[0015] In order to make the technical solutions and advantages of the embodiments of the present invention more clearly expressed, the technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0016] The present invention provides a method and device for acquiring synonyms. The method generates a more accurate synonym pair set by performing invalid word filtering, editing distance processing, cosine similarity filtering, part-of-speech filtering, and building a unigram. The synonym acquisition method and device of the present invention realize that the retrieved synonyms are more accurate, and there are no ambiguous words and invalid words, so that the related webpages of synonyms can be retrieved intelligently and quickly. This method generates a more accurate synonym pair set by performing invalid word filtering, editing distance processing, cosine similarity filtering, part-of-speech filtering, an...

Abstract

The invention relates to a method and a device for obtaining synonyms. The method comprises: obtaining a text set, performing word segmentation on the text set to generate a first term set; filtering null words of the first term set through a stop word list, to generate a second term set; performing distance editing processing on any two words in the second term set, to generate a first synonym set; establishing a vector space model on the words in the first term set; according to the model, obtaining space vectors of each pair of synonyms, calculating cosine similarity value of each pair of synonyms, performing cosine threshold filtration strategy identification on each pair of synonyms, to generate a second synonym set; performing part-of-speech tagging on the words in the second synonym set, to generate a third synonym set; and processing the words in the third synonym set by a unary model, to obtain synonyms. Thus, the method and the device realize that retrieved synonyms are more accurate, and ambiguous words and null words do not exist, so as to intelligently retrieve related webpage of synonyms.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for acquiring synonyms. Background technique [0002] With the rapid development of the Internet, e-commerce has gradually developed. For the on-site search engine of an e-commerce website, it should be as accurate as possible to retrieve web pages matching the synonyms of the search request entered by the user.

[0003] For the construction of the business synonym vocabulary, if it is manually marked one by one, it takes a long time. At the same time, it cannot guarantee that the data can be completely covered. Moreover, it is artificially emotional and empirical. Therefore, the correctness of the artificially generated business synonym vocabulary is certain Subjective elements. [0004] The existing syn...
