微博热门话题提取和分析技术研究
传统的网络文本数据提取一般是利用图遍历的方法通过网络爬虫搜集信息，而本文是利用新浪微博提供的API接口去获取自己想要的微博中的内容。
本文介绍了相关的微博话题检测大致流程和相应算法，本文主要调用中科院ICTCLAS 2014分词系统里已有的关键词提取算法去获得微博话题。从而筛选相应的微博内容，在此基础上，通过情感分类对微博内容进行模型化表示，进一步转换为能通过weka处理的数据格式，进而通过机器学习来进行情感分析。

techniques
Abstract
Today's sina weibo has been very deeply into and affect people's daily lives，with the rapidly growing popularity of smart phones，people just need to be anywhere that people can publish their own state through finger.So it has real-time information and other characteristics of debris.And now sina weibo function continuously improved, began to form their own ecosystem,weibo users can mutual concern and comment, forwarding, like mutual concern people microblogging content, which has a strong interaction and flexibility makes microblogging has a very strong social features.As is now the first social media, weibo huge user base and huge amounts of data thus generated is worth a good study. This paper studies the microblogging data extraction, topic detection and corresponding emotions microblogging content analysis.
Traditional network text data extraction using graph traversal general idea of gathering information through the web crawler, but this paper is to use API interface provided by sina weibo to get what you want microblogging content, only to realize it is convenient to extract data and extract efficiency is very good.
In introducing the relevant microblogging topic detection process and the corresponding algorithms, the paper calls the CASICTCLAS 2014 segmentation system existing keyword extraction algorithm to obtain microblogging topic. Thereby filtering the corresponding micro-blog content, on this basis, through emotional dictionaries for the micro-blog content processing, expressed as processed by weka data format, and then through machine learning for sentiment analysis.
Keywords : microblogging; data acquisition; topic detection; machine learning; sentiment analysis
