Information providing method and device

Abstract

The invention provides an information providing method and device. The method comprises the following steps: targeting to a first set, judging whether the number of each data item in the first set isgreater than a first threshold value or not; if so, calculating an information gain ratio of each selected filling parameter in the selected filling parameter list, selecting an inquiry template corresponding to the selected filling parameter with the maximum information gain ratio to inquire the user; selecting and filling parameter information; deleting the data items which are not matched withthe filling parameter information in the first set; obtaining a new first set, and when the data items in the new first set are not greater than the first threshold value, deleting the selected filling parameter with the maximum information gain ratio in the selected filling parameter list to obtain a new selected filling parameter list, re-judging whether the number of the data items in the new first set is greater than the first threshold value or not until the number of the data items is not greater than the first threshold value, and providing the data items in the new first set for the user. According to the method provided by the invention, the filling parameter with the maximum information gain ratio is selected each time to inquire the user, so that the frequency of interaction with the user is reduced, and the service efficiency is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to an information providing method and device. Background technique [0002] With the advancement of science and technology, the research of robots has gradually gone out of the industrial field and expanded to medical, health care, family and service industries, and people's requirements for robots have also increased from simple and repetitive mechanical actions to humanoid question-answering and autonomy. Human-computer interaction has become an important factor in determining the development of intelligent robots. In the process of human-computer interaction between the user and the robot, the robot determines the corresponding business scenario based on the voice data of the user, and searches for the result corresponding to the voice data according to the obtained parameter information of each limited parameter in the business scenario, and Provide the found results to ...

Problems solved by technology

[0003] In the existing information provision method, for the acquisition of parameter information of all limited parameters, the user is asked questions in a preset order, and the corresponding parameter information is obtained from the user's answer; applying the existing information provision method, the order of questioning depends on the previous period. Carry out manual presets and inquire passengers in the preset order. For business scenarios with a large amount of data, multiple inquiries with users are required, resulting in low service efficiency and poor user experience
