Design And Implementation Of Question Answering System Based On .NET

With the continuous development of the Internet,people come into contact with more and more new things,how to excavate potential from the vast web sources,has become a new hotspot technologies.Question Answering System is a web search based on Baidu knowledge sharing platform,aims to build a bridge between the demanders and the providers,in order to meet the browse needs and develop the value of knowledge.The previous Internet search engine only can search on the existing resources,but baidu makes up for the fact,it can change the tacit knowledge of users into the dominant knowledge and during this process.It can encourage other users to create an answer to the question by integral mechanisms.The answers of these questions will become search results,provide to other users when their questions are similar and finally reach the purpose of knowledge sharing.This article describes the design and realization of baidu system based on ASP asp.net.The platform uses the B/S structure,the user interface are realized through the browser WWW.This system uses ASP.NET3.5 + SQL Server2005 + LINQ + 3 layer architecture technology.This website uses ASP.NET3.5 that provides many advanced technologies,such as LINQ to SQL access SQLServer2005 database.This system starts from the feasibility study,demand analysis and general design,detailed design,database design,code,test.From this design,firstly,it analysis what functions this system should contain according to the actual needs;secondly,it makes a detailed description to functional modules that the system has been implemented,then it makes a display of the system's page and features.Finally,it summed up some experiences that I can have from this research.
