A Man-Machine Dialogue Method for Agricultural Technology Consulting

Abstract

The invention discloses an agricultural technical consultation man-machine conversation method. A man-machine conversation system comprises an agricultural technical netty resource library construction module, an agricultural technical question and answer pair processing module, a user consultation question type judgment module, an agricultural question answering module and a general topic question answering module, wherein the agricultural technical netty resource library construction module is used for associatively organizing texts, pictures and videos and providing a basis for comprehensively answering questions; the agricultural technical question and answer pair processing module is used for extracting topic words of the questions and performing answer information condensation; the user consultation question type judgment module is used for judging the types of the questions and adopting different processing policies for different types; the agricultural question answering moduleis used for calling agricultural answer extraction interface and model to obtain answers; and the general topic question answering module is used for calling a general topic answer extraction interface to obtain answers. Quick development of agricultural technical consultation robots can be realized; agricultural and non-agricultural problems can be flexibly coped with; and all-weather and professional image-text video multimedia comprehensive accurate answering is provided.

Description

1. Technical field [0001] The invention belongs to the technical field of agricultural information, and relates to a man-machine dialogue method for accessing agricultural knowledge, in particular to a man-machine dialogue method for agricultural technical consultation. 2. Technical Background [0002] With the development of information technology, information service has developed from Internet information service and mobile information service to the development stage of information service based on artificial intelligence. On July 8, 2017, the State Council's "New Generation Artificial Intelligence Development Plan" was released, clearly pointing out that it will promote the widespread application of new generation artificial intelligence in fields such as smart agriculture. At present, artificial intelligence-based service robots have outstanding advantages in reducing labor costs and providing all-weather man-machine dialogue services, but there are still obvious short...

AI Technical Summary

Problems solved by technology

[0003] (1) Lack of agricultural professional technical knowledge, unable to provide professional answers to agricultural technical problems;

[0004] (2) Man-machine dialogue is random. Users will cover agricultural professional issues and general issues (such as weather, traffic, etc.) during the consultation process. If a complete agricultural professional knowledge base and general topic question and answer database are established at the same time, the workload will be huge. Low development efficiency;

[0005] (3) The agricultural consultation problem in the process of man-machine dialogue is often a short text description. In the traditional method, the similarity calculation method based on statistics is not accurate due to the small vocabulary of the text; It is difficult to build a professional semantic web, and it is not applicable because there is no existing semantic web available;

[0006] (4) The problems of agricultural production are complex, and the scientific and technological quality of farmers is not high. In addition to voice interaction, they often need to explain through pictures and related videos. Currently, service robots that only interact through voice cannot fully answer user consultation questions
