Embodiment 2

[0079] As a specific implementation method of updating the sentence path probability in the above sentence path probability calculation embodiment, considering that in practical applications, the part-of-speech connection probabilities corresponding to different segmented sentences corresponding to the same sentence are more likely to be the same or similar (because the part-of-speech There are extremely limited types, and the corresponding possible part-of-speech connection probability is also extremely limited), which makes the sentence path probability calculated based on the part-of-speech connection probability poorly applicable. Therefore, in order to ensure that reliable target segmentation can be successfully selected based on the sentence path probability statement, such as figure 2 As shown, Embodiment 2 of the present application includes:

[0080] S201. Extract the first segmented statement with the largest statement path probability among the plurality of first s...

Abstract

The invention provides a keyword extraction method and device and terminal equipment, and is suitable for the technical field of data processing, and the method comprises the steps: carrying out the word searching of a to-be-processed statement based on a preset dictionary, carrying out the statement segmentation of the to-be-processed statement based on the searched words, and obtaining a plurality of corresponding first segmented statements; screening out a target segmentation statement with the maximum statement path probability in the plurality of first segmentation statements; performingcontinuous word combination on words in the target segmentation statement to obtain a plurality of corresponding to-be-detected words; and performing legal term screening on the to-be-detected words based on a preset legal term library to obtain corresponding legal term keywords. According to the embodiment of the invention, when the keywords are finally screened, the keywords are not only limitedby simple basic words, but also legal terms obtained by combining the basic words can be identified, so that the accuracy of extracting the legal term keywords is greatly improved.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a keyword extraction method and a terminal device. Background technique [0002] Keyword is the smallest unit to express the theme of a document, so it is a very important link in natural language processing, such as automatic summarization, automatic classification, information retrieval, information extraction, knowledge mining, etc., all need to extract keywords first. There are some keyword extraction methods in the prior art, such as TextRank algorithm and topic model, etc., but these keyword extraction methods are all aimed at keyword extraction in daily life sentences, and for legal terms, due to their professional The difference between strong and daily-used words makes the accuracy of these keyword extraction methods unsatisfactory for the extraction of legal term keywords. At the same time, there is no method for extracting legal term keywo...
