Design And Implementation Of Information Trace System Based On Sina Micro-Blog

In recent years,Micro-Blog has become one of the most popular online social network platforms.With the rapid development of Micro-Blog,the number of information propagation has rapidly increased.Under such enormous amount of information,Micro-Blog information trace has become the main research topic in the field of Micro-Blog information propagation,which is the important foundation in Micro-Blog information screen,event propagation situation analysis,public opinion monitoring and many other related fields.This thesis designs and implements an information trace system based on the Sina Micro-Blog.According to the practical functional requirements,the system is divided into two subsystems,including Sina Micro-Blog information collection and information analysis.Sina Micro-Blog information collection subsystem mainly includes API-based information collection,cookie-based information collection,anti-crawl and information management module.The first subsystem crawls information by multi-thread and incremental.Micro-Blog information collection mainly includes Micro-Blog content,comment list,repost list and user information.Information analysis subsystem mainly includes Micro-Blog event analysis,users influence analysis and information trace module.Event tracing in Sina Micro-Blog mainly takes two factors,time and influence,into consideration.System uses the MyEclipse development tools,and combines the MySQL database.For the front desk for the display of user interface,JSP technology is used and for background,the Java programming language is uesed.After the system is developed,it proves the system achieves the goal of information tracing by functional testing and non-functional testing.This thesis describes the entire process of the system development,including requirements analysis,design,implementation and system test.System uses web crawler,API-based information collection,LSA-based text aggregation,influence analysis and other core technologies to achieve information trace system in online social network based on Sina Micro-Blog.
