Embodiment Construction

[0028] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In a noisy environment, the voice recognition of user input is very low, which makes it easy to make mistakes when converting voice into text, including many words, few words or wrong words, etc., so there will be errors in determining the type of text, which will affect the accuracy Determine the user's intent. Based on this, the embodiments of the present invention provide a tex...

Abstract

The invention provides a text classification method and device, a computer readable storage medium and electronic equipment. The method comprises the steps that word division is conducted on a to-be-classified text, multiple segmented words and word attributes of each segmented word are obtained, and the word attributes comprise at least one type attribute and a heat attribute corresponding to each type attribute; entence pattern matching is performed on the text according to the length of each segmented word and the type attribute of each segmented word in a sentence pattern database to obtain a plurality of matched sentence patterns; wherein each matched sentence pattern comprises a plurality of matched segmented words, a target heat attribute of each matched segmented word, sentence pattern scores and sentence pattern categories; a target sentence pattern from the plurality of matched sentence patterns is determined according to the number of the segmented words, the target heat attribute of the segmented words and the sentence pattern scores in each matched sentence pattern; and the sentence pattern category to which the target sentence pattern belongs is determined as a classification result of the text. According to the invention, when the identified text is subjected to category judgment, the category judgment accuracy and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence algorithms, and in particular, to a text classification method, an apparatus, a computer-readable storage medium and an electronic device. Background technique [0002] When judging the category of the voice input by the user, the voice is first converted into text, and the text is generally short text, and short text usually refers to the text form with a short length, generally no more than 160 characters, such as Weibo, chat Information, news topics, question texts, mobile text messages, etc. The purpose of short text classification is to automatically process the identified short texts to obtain valuable output. In the construction process of Chatbot (chat robot), the recognition of user's intention is a more important part, and the core problem of intention recognition is how to classify short texts. Taking short texts as an example, there are usually rule-based mode...
