Description

public number question-answer response method and device

Technical Field

the invention belongs to the technical field of voice recognition, and particularly relates to a public number question-answer response method and device.

Background

in the related art, in some schemes, in some wechat public account dialogue services provided by an artificial intelligence dialogue service platform, the content of a public account article can be independently learned and used as a dialogue material. In other schemes, a public operator can configure search functions such as search in a number, and provide a search tool for article contents.

In the scheme of the autonomous learning, when a question is received, the technology can search the content which can be used for answering from the content of the article and extract the content of the article for answering the question. And the user can manually control whether to participate in question answering or not in the management platform by using the article as an alternative answer.

The scheme of searching in numbers is mainly to search for matched contents in a special search page in a keyword retrieval mode. The search-in-number scheme is an application mode of a traditional search engine tool in the vertical field.

The inventor finds that the prior scheme has at least the following defects in the process of implementing the application:

The defects of the autonomous learning scheme are as follows:

1. most of the self-help learning modes only support clear contents in partial fields, such as brief introduction of a certain object, scenic spot operation time and the like, and the contents are clear and definite in structure. This puts high demands on the content of the article itself, and the supported questionable content is also limited by the model training progress.

2. when the conversation relates to article contents, only a part of the article contents are selected to be pushed out as an answer, and the whole article is not recommended. On the one hand, incomplete answers, or lack of contextual information, may result in excerpts; on the other hand, the number of the articles exposed and read is also reduced, which causes traffic loss for the operator.

3. Whether the articles are used as a question and answer material library or not needs to be manually regulated in the platform, although the degree of freedom of operation is improved, the operation cost is increased for the public numbers with a large number of articles and guaranteed article quality or needing to increase or delete the articles frequently.

Defects of search-in-number scheme:

1. the method is suitable for inquiring in a search interface, and users need to have the consciousness of active search and cannot support the direct realization of similar functions in a conversation interface.

2. the keyword search has high requirements on the information literacy of users, and the required content can be found quickly only by mastering a certain keyword extraction skill.

In step 103, a material library and an index file are established at least based on the identified content, wherein the material library comprises the article materials published by the public number, and the index file is an index corresponding to the article materials.

In this embodiment, for step 101, the public number may be bound to the server side corresponding to the corresponding device through the operation of the user at the user terminal, so that the server side may have a right to collect article materials published by the public number, and the server side may monitor the public number in real time, so that the article materials are updated to the server side in time after being published by the public number, and the content of the public number may also be updated synchronously at regular time, for example, once a day or twice a day, which is not limited again in this application.

For step 102, after the server collects the article materials of the public number, the server may separately identify the content of the updated article materials by using an automatic reading and understanding technology, and update the material library and the index file only according to the updated article materials. Certainly, the server side may also perform content identification on recent articles in a unified manner according to updated article materials, and rearrange the index files, where the method may be directed to the case where there are fewer public numbers and fewer contents, and if there are more article materials, the load of identifying the server side according to the above method is small, which is not described herein again, and the present application is not limited herein.

For step 103, the server establishes a material library and an index file at least based on the identified content, wherein the material library comprises the article materials listed by the public number, the index file is an index corresponding to the article materials, and the article materials related to the material library can be quickly located by searching the index file, so that the time for searching is reduced, and the response speed is increased. The index file can include, for example, article titles, subtitles in the articles, and association relations between keywords and the articles, and a user can associate the index file with corresponding content by searching for the corresponding content, and can quickly find the corresponding articles through the index file.

the method of the embodiment identifies the content of the article material by automatically reading and understanding the article material published by the public at the server side, thereby establishing a corresponding material library and an index file of the article material in the material library. Therefore, a corresponding material library and an index file are established for the published articles of the public number, so that the articles of the public number can be found more easily, and the exposure rate is improved.

In some optional embodiments, the step 103 further includes: establishing a material library based on published article materials of the public number, and automatically synchronizing and updating the material library based on the operations of adding, modifying and deleting the article materials of the public number; and generating a corresponding index file based on the identified content and the structured information of the published article material. Therefore, when the material is subjected to operations such as addition, modification and deletion, the material can be synchronized and updated in time, and invalid content can be deleted in time. Furthermore, data synchronization can be performed at regular time every day to ensure that newly added and changed contents can be timely recorded by the system and the timeliness is ensured; at the same time, the deleted material can be cleared from the library so that invalid content is not pushed out. The structured information of the article materials may include titles of the articles, abstracts of the articles, search information or keywords, and the like.

referring to fig. 2, which shows a flowchart of another embodiment of the public number question-answering response method of the present application, the public number question-answering response method of the present embodiment may be applied to a user terminal with voice recognition and understanding capabilities, such as an intelligent voice television, an intelligent sound box, an intelligent dialogue toy, and other existing user terminals with semantic recognition and understanding capabilities.

In step 201, in response to receiving a question of a user, performing semantic understanding processing on the question to extract an intention of the question;

In step 203, sorting at least one candidate result based on a preset index;

In step 204, at least one candidate ranked in the front is sent to the user as a recommendation.

in this embodiment, for step 201, in response to receiving a question of a user, the user terminal performs semantic understanding processing on the user question to extract an intention or keyword information of the question, so that subsequent processing can be performed according to the intention or keyword information, where the intention or keyword may be, for example, the latest discount information of a certain clothing brand, the latest policy of a country for a certain region, and the like. Then, for step 202, the user terminal sends a corresponding search request to the server terminal based on the intention of the question, and then the server terminal searches the index file based on the search request, and then finds the associated article materials, forms a candidate set, and feeds the candidate set back to the user terminal, where the candidate set is a set of at least one candidate result.

Then, for step 203, the user terminal performs priority ranking on at least one candidate result in the candidate set according to preset indexes, where the preset indexes include material evaluation indexes and user attribute indexes, the material evaluation indexes may be indexes used for evaluating relevance and real-time performance of materials, and the user attribute indexes may be interests and history records of the user, which is not limited herein. It should be noted that, this step does not necessarily need to be completed at the user terminal, and may also be completed at the server side, and the application is not limited herein.

Finally, for step 204, the user terminal sends at least one candidate result ranked in the front to the user as a recommendation result according to the ranking result. For example, a candidate result ranked first may be recommended directly to the user, or several candidate results may be recommended to the user, which is not limited herein.

According to the method, the intention and/or keywords of the user question are/is extracted by semantically understanding the user question, a candidate set with high relevance is found from a material library of a server side according to the intention, at least one candidate result in the candidate set is ranked according to the attribute of the article and the attribute information of the user, and the result ranked in the candidate set is recommended to the user, so that the result recommended to the user is more in line with the expectation of the user, the recommendation is more accurate, and the user experience is better.
