Problems solved by technology

[0003] Therefore, the technical defect in the prior art is: in the existing human-computer dialogue system, there is no dialogue topic factor representing the user's personality added to the user portrait, so that in the process of man-machine dialogue, it is impossible to give more intelligent information according to the user's personality. answer

Embodiment 1

[0049] figure 1 It shows a flow chart of a user portrait modeling method based on topic detection in text dialogue provided by the first embodiment of the present invention; figure 1 As shown, the user portrait modeling method based on topic detection in text dialogue provided by Embodiment 1 of the present invention includes:

[0050] Step S1, obtaining multiple topics of the text input by the user through the topic recognition system, the multiple topics include main topics and secondary topics;

[0051] Step S2, mapping multiple topics into a graph-structured topic relationship graph to form a topic map;

[0052] Step S3, update the topic map through logical rules or machine learning methods to obtain the user portrait of the user.

[0053] The technical solution of the user portrait modeling method based on topic detection in text dialogue provided by the present invention is: firstly obtain multiple topics of the text input by the user through the topic recognition syst...

Embodiment 2

[0108] The user portrait modeling method based on topic detection in text dialogue provided by Embodiment 1 of the present invention, and the user portrait modeling system 10 based on topic detection in text dialogue are applied to a man-machine dialogue system, and the specific process is as follows:

[0109]The user enters a text sentence, for example: Is there any news about Faye Wong?

[0110] The topic recognition system detects the topic in the sentence that the user is talking about. For example, the main topic in the previous sentence is "artist" and the secondary topic is "singer";

[0111] Map the main topic "artist" and the secondary topic "singer" to the topic map;

[0112] According to logical rules or machine learning algorithms, the personalized map (topic map) is updated. Through the topic map, it is possible to know the degree of personal preference for different topics and give intelligent answers.

[0113] Through the user portrait modeling method and syste...

Abstract

The invention provides a user portrait modeling method and system in a text dialogue based on topic detection. The user portrait modeling method comprises the following steps: obtaining a plurality of topics in a text inputted by a user through a topic recognition system, wherein the plurality of topics comprise main topics and secondary topics; mapping the plurality of topics into a topic relationship diagram with a graph structure to form a topic map; updating the topic map through logic rules or a machine learning method to obtain a user portrait of the user. The user portrait modeling method and system in the text dialogue based on the topic detection, provided by the invention, have the benefits that the topics in the user dialogue text are divided into the main topics and the secondary topics, and the topic map is updated through establishing the topic map for the main topics and the secondary topics according to the topics included in a dialogue content of the user, so that the user portrait of the user is obtained; according to the user portrait, user personality factors are considered in the man-machine dialogue process, so that a man-machine dialogue is more intelligent.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to the field of artificial intelligence dialogue. Background technique [0002] Existing artificial intelligence dialogue systems model users based on their own information, such as gender, age, hometown, occupation, etc., and do not take user personality, such as topics of interest, as factors in forming user portraits. In natural conversations between people, frequently discussed topics represent personal interests. Therefore, in the artificial intelligence dialogue system, the topic that the user is interested in is an important factor in the user portrait. [0003] Therefore, the technical defect in the prior art is: in the existing man-machine dialogue system, there is no dialogue topic factor representing the user's personality added to the user portrait, so that in the process of man-machine dialogue, it is impossible to give more intelligent information according to t...
