摘 要

随着新型科技及新兴媒体的不断崛起，与往日不同,主流媒体并非为突发性事件报道的唯一途径。微博因其独特的优势在各种媒体传播中崭露头角，已成为许多热点事件及突发性话题的重要传播手段。作为脱颖而出的新媒体，公众微博为传统媒体提供了热点话题的相关信息。在微博中，每日都有大量的话题，用户在大致浏览后，可根据自身的喜好在当中选取感兴趣的话题，然后阅览并发表评论。如若要进一步地了解某一热点话题，用户需浏览更多的相干的话题，从而更加清晰地明白事件的发展形态。另外，用户也可采用不断刷新的方式来浏览更多的话题，了解其评论热度及转发量，从而跟踪最新热点话题。但是，这样无疑需要消耗极大的精力，并且还不能获得完整的信息，达到理想效果。那么如何在成千上万的微博话题当中自动查找出热点，使得用户能够快速浏览话题，已成为当下一个研究热点。值得一提的是某些情报信息的发掘及分析在一些特殊部门的业务应用工作中起到了举足轻重的作用。微博内容真实地来源于生活，它提供了许多研究人类日常生活规律的相关资料，为数据开发提供了宽广的发展机遇。

本文为三部分探讨公众微博突发性话题检测方法的设计与实现：数据采集、数据分析处理、界面结果显示的过程。实现的功能主要是：管理员登陆、微博导入、按照顺序和分类推送热点、微博展示和用户登录界面。

该检测系统基于web方式。在开发过程中使用Mysql作为数据库，运用Myeclipse作为开发工具对各个功能模块进行实现。

Abstract

The development of new technology, new media, makes the traditional mainstream media is no longer the only protagonist incident reports, as an important representative of new media, with its unique advantages, in many important events and hot topic has played a pivotal role. Public weibo serves as emerging new media, has become an important source of tracking breaking the traditional media. Weibo is arises at the historic moment under this era. With unique technology and advantages, it quickly became a leader in the transmission report public emergency.there are thousands of topics In weibo every day, weibo users can choose their topic of interest to browse, read the content of the topic and comment. If you want to a deeper, more comprehensive understanding of a topic, you need to constantly click browse relevant to understand the content of the event development process. Weibo users if you want to understand the latest hot topics also needs by constantly refresh to browse a lot of topic and comment on heat and forwarding number, such not only spend a lot of energy, and understand the information may not be complete, can not get ideal results. How to implement weibo in a wide range of topics from quantity automatically has been the hot topics , convenient managers to quickly understand the current hot topic become a research hotspot. And in some special departments of business applications, the intelligence information mining and analysis of the work has the extremely important support role. And at the same time, weibo data also reflects the user's actual life truthly, to summarize the research on the rules of human's daily life to provide a large number of corpus, brings to the field of data mining the vast opportunities and prospects for development.

In this paper, for the three parts to discuss the public weibo sudden topic detection method: the design and implementation of data acquisition, data analysis, results show that the interface process. To realize the main functions are: administrator login, micro into tutors, classified according to the order and push hot spots, weibo display and user login interface.

The detection system based on web. In the development process using Mysql as a database, using the Myeclipse as a development tool to realize various functional modules.

Keywords: microblogging, MyEclipse, classification, hot
