Design And Implementation Of Intelligent Question And Answer System Based On Specific Scene

With the rapid development of Internet information technology,there are more and more data on the network.The current obstacle to the development of computer technology is not the lack of information,but the information overload.In this case,the intelligent question answering system arises at the historic moment.This kind of system is designed to be carried in different use scenarios to solve the problem of information overload and provide users with an accurate answer.The Intelligent Question Answering System Based on specific scenarios is developed by Java,using springboot,mybatis as the implementation framework,and using mysql,redis and other database technologies to store data.At the same time,the MVC mode is used for the overall design to ensure the flexibility,scalability and maintainability of the system.Based on the detailed analysis of product functional requirements and user characteristics,the intelligent question answering system is divided into four modules(1)Dialogue Engine module: This module implements Q & A function in a specific field.The module is the external display interface of the question and answer system.After the user initiates a question,the content response is completed through the processing of retrieving or task-based question and answer.(2)Robot configuration module: This module achieves specific configuration functions for robots in different scenes.It is mainly used to set the initialization interface and session mode of robots in different scenes in the dialogue engine.(3)Retrieval Question and Answer Module: This module implements functions such as knowledge base management,unknown question management,etc.It is mainly used for one-round retrieval question and answer mode,which identifies user's natural questions and matches them with the questions in the knowledge base.If there are no matching questions,it is added to the unknown questions,and then the unknown questions can be added or related to the knowledge base.(4)Task-based Question and Answer module: This module implements the functions of task scenario management,glossary information management,etc.It is mainly used in multi-round task-based question and answer mode,identifies user's natural questions and matches them with task scenarios,initiates counter-questions,completes user's required parameter information according to glossary configuration,and completes system's reply.The online operation results show that the system fully realizes the effective integration of Task-based Q & A and retrieval based Q & A,which is easy to operate,accurate and fast to answer,not only meets the actual needs of users,reduces the consumption and waste of human resources,but also greatly improves the overall work efficiency of the company.At present,the system is still continuously updated and iterated through data feedback,hoping to be put into more diversified use scenarios in the future,bringing more rich economic benefits for the company and more effective intelligent services for the society.
