Embodiment ( 1

[0125] see Figure 4 , Figure 4 It is a flow chart of a method for obtaining target hot text provided by the embodiment of the present application, and the method can be composed of the above-mentioned figure 2 The execution device 200, the first training device 300, the second training device 400, and the target hotspot text acquisition module 202 in the execution device 200 are executed. The embodiment of this application takes the execution device as an example for illustration. The method may include, but is not limited to, the following steps:

[0126] S100: The execution device selects a target hotspot set to which the target text belongs from multiple hotspots sets.

[0127] In one implementation, the similarity between the target text and each hot text in the first hotspot set can be calculated, and then, the similarity between the target text and each hot text in the first set is summed to obtain the target text in The similarity on this hotspot set. Wherein, th...

Abstract

The embodiment of the invention discloses an intention recognition method, device and equipment. A to-be-recognized text is obtained; the to-be-recognized text and the hot spot features corresponding to the to-be-recognized text are input into an intention recognizer, a recognition result is output, the intention recognizer is a neural network used for recognizing multiple intentions, the recognition result is used for indicating the intentions of the to-be-recognized text, and the hot spot features are features extracted from a target hot spot text; the target hot text comprises at least one hot text similar to the to-be-recognized text. Therefore, the intention recognition method considers that the hot spots change along with the change of time and the same to-be-recognized text possibly corresponds to different intentions, so that in the intention recognition process, the to-be-recognized text is combined with the hot spots, and the hot spot features are extracted from the hot spot text related to the to-be-recognized text; therefore, the timeliness of the intention can be concerned, and the intention recognition accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to an intent recognition method and related devices and equipment. Background technique [0002] Question Answering System (QA) is widely used in daily life, such as voice assistant, search engine or search system. The question answering system recognizes the intention of the information by automatically processing the input information, so that the device can respond accordingly, meeting the needs of people to obtain information quickly and accurately, or to enable the device to execute related commands. However, in the question answering system, how to accurately identify the intent is still one of the difficulties and pain points of the current technology. Only by accurately discovering or locating the real intent of the information entered by the user can the user be provided with the feedback he most wants, and the user can be improved. experience...
