Abstract

The invention provides an intention understanding method and device, and the method comprises the steps: recognizing a target word slot label corresponding to a composition word in a target text, andgenerating a target generalized text of the target text according to the target word slot label; matching the target generalization text with a plurality of preset generalization templates, and determining candidate generalization templates according to the matching degree; calculating the semantic similarity between the target generalization text and the candidate generalization template, and determining the target generalization template according to the semantic similarity; and obtaining a template intention of the target generalization template, taking the template intention of the targetgeneralization template, and generating an intention understanding result of the target text according to the template intention, the target word slot label and the composition words corresponding tothe target word slot label. Therefore, intention understanding of related information is realized based on a generalization processing mode, dependence on a large number of annotation training samplesis avoided, annotation workload and difficulty of a sample person are reduced, and intention understanding modes are enriched.

Description

technical field

[0001] The present invention relates to the technical field of information processing, in particular to an intent understanding method and device. Background technique

[0002] Usually, understanding the intention of natural language is an indispensable part of the current intelligent scene. The task of understanding spoken dialogue is one of the tasks of natural language processing. The usual processing method is: define an intention set and entity word set, Each intent can correspond to a subset of the entity word set, and each spoken sentence can correspond to one or more intents in the intent set, and the sentence can contain several word fragments, and each fragment corresponds to an entity word.

[0003] In related technologies, the oral dialogue comprehension task uses training data such as labeled samples or templates to realize the recognition of the intent and entity words of spoken sentences, matches based on manually labeled templates, and uses a ...
