Embodiment 1

[0039] This embodiment will be described from the perspective of an automatic question answering device, which may be integrated in one entity or multiple entities; for example, the automatic question answering device may be integrated in a server or other equipment.

[0040] An automatic question-answering method, comprising: multiple question-answer pairs formed based on social data on social platforms, the question-answer pairs including questions and corresponding answers, and then establishing an inverted index of the questions and their phrases, obtaining retrieval questions, and According to the question phrase of the retrieval question and the inverted index, determine a similar question similar to the retrieval question, obtain a candidate answer to the retrieval question according to the similar question and the question-answer pair, and obtain a set of candidate answers to the retrieval question, from the set of candidate answers Select the target answer for the sear...

Embodiment 2

[0191] According to the method described in Embodiment 1, an example will be given below for further detailed description.

[0192] In the embodiment of the present invention, the automatic question answering method provided by the present invention is introduced by taking the automatic question answering device integrated in the server as an example.

[0193] refer to Figure 2a , the embodiment of the present invention provides an automatic question answering system, including a server and a terminal, the server is integrated with an automatic question answering device, and the server and the terminal are connected through a network.

[0194] Such as Figure 2b As shown, an automatic question answering method, the specific process can be as follows:

[0195] 201. The server acquires social data on the social platform, and performs data filtering on the social data.

[0196] Among them, the social platform refers to a platform that provides users with information such as s...

Embodiment 3

[0242] According to the methods described in Embodiments 1 and 2, examples will be given below for further detailed description.

[0243] The embodiment of the present invention provides an automatic question answering system, refer to Figure 3a , the self-questioning system may include: an online retrieval system, an offline processing system, and a sorting system.

[0244] The automatic question answering system realizes the process of chatting, as follows:

[0245] The offline processing system obtains massive social data (such as UGC data) on social platforms, performs data cleaning (data filtering) on ​​the massive social data, and then disassembles the social data into question-answer pairs and QA pairs, and releases the QA pairs. into the online retrieval system. For example, the offline processing system can filter out named entities such as person names, place names, and organization names, private data such as phone numbers, instant messaging numbers, and bank car...

Abstract

Embodiments of the invention disclose an automatic question and answer method and apparatus, and a storage medium. The method comprises the steps of adopting multiple question and answer pairs formedbased on social data in a social platform, wherein the question and answer pairs comprise questions and corresponding answers; then, establishing reverse indexes of the questions and corresponding word groups; obtaining a retrieval question; according to a question word group of the retrieval question and the reverse indexes, determining similar questions similar to the retrieval question; according to the similar questions and the question and answer pairs, obtaining candidate answers of the retrieval question, thereby obtaining a candidate answer set of the retrieval question; and selectinga target answer of the retrieval question from the candidate answer set. According to the scheme, the answer matched with the retrieval question can be output, so that the accuracy and quality of output answers of a chat robot system are improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an automatic question answering method, device and storage medium. Background technique [0002] The chat robot system is an artificial intelligence system that can be online at all times by means of communication and communicate with people through natural language. A chatbot system is essentially an automated question answering (QA) system. The automatic question answering system, also called question answering system, is a computer processing system that memorizes a large corpus, automatically retrieves and answers user questions. [0003] Specifically, after the user inputs a question, the chat robot system searches the database for an answer that matches the question, and then outputs the retrieved answer to answer the user's input question, thereby realizing chatting. [0004] However, the current chatbot system often has a situation where the answer does ...
