Abstract

The application provides a method and device for recognizing a sentence. The method comprises the following steps: determining a non-stop word as a key word for an acquired sentence to be recognized; selecting a candidate sentence including the key word of the sentence to be recognized in a preset sentence library; determining a subject classification tag and an intention classification tag for the sentence to be recognized through a classification model which is built in advance, wherein the classification model can recognize an intention of an unknown type; when the recognized intention classification tag is of an unknown type and a plurality of candidate sentences exist, grouping the candidate sentences according to a preset intention tag; displaying the preset information corresponding to the candidate sentence in each group. Different groups correspond to different intention types, and the candidate sentence in each group is selected as a target sentence to display the preset information corresponding to each target sentence, thus, the problem that information fed back is single or even cannot be fed back is solved.

Description

technical field [0001] The present application relates to the technical field of language data processing, in particular to a sentence recognition method and device. Background technique [0002] In the field of natural language processing, it is often necessary to recognize the intent of natural language to automatically generate feedback information. For example, in the automatic question and answer, the user enters the sentence "why the refrigerator is not powered on", and needs to recognize the intent of the input sentence to feedback the reason why the refrigerator is not powered on. [0003] Due to the complexity of natural language, one sentence often corresponds to multiple different sub-intents. For example, the sentence entered by the user is "the refrigerator is not powered on". In this case, the user may want to ask why the refrigerator is not powered on, or may I want to ask about the solution to the refrigerator not being powered on. [0004] At present, for ...
