Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] For ease of understanding, before describing the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention are firstly introduced.

[0064] In the embodiment of the present invention, the user can input voice to retrieve content such as movies and music in the smart TV or control the smart TV to perform corresponding control operations, but before controlling the smart TV to retrieve or perform corresponding control operations , the smart TV needs to convert the voice input by the user into a voice control text, and needs to locate the voice control text to a specific voice control service, and then perform retrieval or corresponding control operations. That is...

Abstract

The invention discloses a method and a device for positioning a voice control service, which belong to the technical field of smart television. The method includes the following steps: segmenting the words of a voice control text to get a word segmentation result; carrying out resource annotation on the word segmentation result to get a resource annotation result; searching for a service classification template matching the voice control text in preset service classification templates based on the word segmentation result and the resource annotation result; and when no matching service classification template is found, analyzing the syntactic structure based on the word segmentation result and the resource annotation result and according to a custom semantic dependency relation to determine a voice control service corresponding to the voice control text. By analyzing the syntactic structure of the voice control text, the syntactic structure information is retained, voice control text comprehension error is avoided, and the accuracy of voice control service positioning is improved.

Description

technical field [0001] The invention relates to the technical field of smart TVs, in particular to a positioning method and device for voice control services. Background technique [0002] With the rapid development of smart TV technology, it is more and more popular to control smart TVs by voice. Among them, the user can input a voice control command to retrieve content such as video, music, etc. in the smart TV or control the smart TV to perform corresponding control operations. Before the smart TV is controlled by voice to retrieve or perform corresponding control operations, the smart TV needs to convert the voice input by the user into a voice control text, and needs to locate the voice control text to a specific voice control service, and then perform the retrieval or control operation . For example, the voice control text obtained through the conversion of the voice input by the user is "Andy Lau's Drama Movie God of Gamblers", the voice control text can be located ...
