Embodiment Construction

[0026] In order to better introduce the embodiments of the present application, some concepts in the embodiments of the present application are introduced below.

[0027] Banking job text: Banking job text refers to the text information generated when banks conduct business processing. Banking job texts vary in length, theme, and content.

[0028] Job hotspots: keywords obtained by analyzing banking job texts through algorithm models are called job hotspots.

[0029] Topic-word pair (biterm topic mode, BTM) model: It is an improved model on the LDA topic model, which obtains the topic word set of relevant banking job texts by calculating the probability distribution of topic-word pairs (Topic-Biterm). .

[0030] Text Rank (TextRank) algorithm: Inspired by the PageRank algorithm, it can divide the banking job text data into several components (words, sentences) and establish a graph model, and use the voting mechanism to sort the importance to get keywords and other informatio...

Abstract

The invention provides a text keyword sensing method and related device. The method comprises the steps that a server obtains a first text; the server obtains a user dictionary, wherein the user dictionary comprises a bank industry terminology; the server performs word segmentation processing on the first text based on the user dictionary to obtain a first word segmentation result; and the server perceives the keyword of the first text based on the first word segmentation result. According to the technical scheme, when the text keywords are obtained, the user dictionary comprising the terminologies of the banking industry is used, so that the word segmentation result is more accurate, and the accuracy of the keywords is improved.

Description

technical field [0001] The present application relates to the field of natural language processing, in particular to a method and a related device for perceiving text keywords. Background technique [0002] The banking industry is very sensitive to the development of the industry situation. Timely and accurate perception of key words in the banking operation text can help sort out and clarify the current industry business, technology, industry status and trends, and provide a realistic basis for banks to make strategic decisions related to operations; On the one hand, it can better grasp the current development direction and focus of banking operations, and provide innovative theories and methods for the development of bank income generation. [0003] In the prior art, when perceiving keywords, first obtain the banking job text and the user dictionary, then perform word segmentation processing on the banking job text according to the user dictionary, obtain the first word se...
