Embodiment 1

[0022] figure 1 It is a flow chart of the automatic question answering method provided by Embodiment 1 of the present invention. This embodiment can be applied to web page automatic reply service. Users can log in to a designated website through the client terminal to ask questions, and the server uses this method to query the answer and send it to the client terminal.

[0023] 110. Obtain user query information;

[0024] Wherein, the query information may be text information input by the user. For example, the user logs in to the automatic reply service website on a personal computer, enters query information in the designated column, and the server obtains the query information; or the user can install automatic reply service software on the personal computer, enter the query information in the software, and send it to server, and the server acquires the query information. The user can also input voice information, and the voice is recognized by voice recognition software ...

Embodiment 2

[0030] figure 2 It is a flow chart of building knowledge scenarios in the automatic question answering method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, this embodiment adds the operation of constructing knowledge scenarios on the basis of the above embodiments.

[0031] Before the query results are associated with the data query scene according to the query information and the question and answer of at least one knowledge scene, the automatic question answering method provided in this embodiment also includes:

[0032] 210. Obtain an item and at least one attribute of the item from a data source.

[0033] Wherein, the data source may be a website carrying knowledge materials, a knowledge encyclopedia website, etc., and the automatic question answering system obtains data from the above websites. The storage form of knowledge data in the data source is generally to store all relevant information of the same subject as a unit. For exampl...

Embodiment 3

[0042] image 3 It is a flow chart of constructing knowledge scenarios in the automatic question answering method provided in Embodiment 3 of the present invention. Such as image 3 As shown, this embodiment provides another solution for constructing knowledge scenarios. This embodiment is more suitable for situations where the attribution between question-answer questions and knowledge scenarios is unclear, and can be called weak-mode knowledge scenarios.

[0043] Specifically, before the data query scene is associated with the query result according to the query information and the question and answer of at least one knowledge scene, the automatic question answering method provided in this embodiment also includes:

[0044] 310. Obtain at least one question-answer pair from the data source.

[0045] Wherein, the data source may be a website storing knowledge information in the form of question and answer, and the automatic question answering system directly obtains questio...

Abstract

The embodiment of the invention provides an automatic question and answer method and system. The method comprises the following steps of obtaining querying information of a user; querying a scene associated query result according to the querying information and question and answer pair data of at least one knowledge scene, and returning to the user, wherein the knowledge scene question and answer pair data comprise at least one question and answer pair, and the question and answer pairs are provided with a set association relationship. According to the technical scheme of the embodiment of the invention, various question and answer pairs are organized in the form of a knowledge scene, and the association relationship of the question and answer pairs is established; therefore, when the user queries, the user can obtain the query result associated with the scene, and can obtain abundant and flexible results by utilizing the association relationship among the question and answer pairs, so that the problem that the question and answer result is single is avoided.

Description

technical field [0001] The embodiments of the present invention relate to computer data processing technology, and in particular to an automatic question answering method and system. Background technique [0002] Automatic question answering refers to the technology in which the user interacts with the computer, and the computer automatically returns the answer by asking the user a question. [0003] The existing automatic question answering technology relies on computers to collect a large amount of knowledge data, store them in the form of question-answer pairs, and form a question-answer pair database to provide users with the information they need. When receiving the question raised by the user, that is, the query information, the system searches the database for a matching question according to the keywords in the query information, and then returns the answer to the question. [0004] However, the information collected in the existing database is relatively independen...
