Abstract

The invention relates to a text processing method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining a target text sequence of a target text, and extracting a subject term sequence from the target text sequence; respectively obtaining semantic distances between all words in the target text sequence and the subject term sequence, and determining a keyword sequence of the target text based on the semantic distances; obtaining a vector of each keyword in the keyword sequence to construct a word vector matrix; obtaining a semanticweight parameter matrix of the target text through a preset random gradient descent algorithm; and obtaining a semantic vector of the target text according to the word vector matrix and the semanticweight parameter matrix. According to the text processing method provided by the invention, the semantics of the target text can be expressed more accurately.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a text processing method, device, electronic equipment and readable storage medium. Background technique [0002] In natural language processing tasks, word vectors can effectively capture the semantic information and grammatical information of the word context, and realize the vectorized representation of words. It is a bridge for computers to understand human language. In order to represent text into data that computers can understand and process easily, Often it is necessary to convert text to vectors. [0003] At present, an algorithm is usually used to convert text directly, for example, the Word2Vec model is used to directly convert text, and the semantics obtained after conversion are often not accurate enough. Contents of the invention [0004] The purpose of this application is to at least solve one of the above-mentioned technical defect...
