新闻数据可视分析系统

A Visual Analysis System for News Data

  • 摘要: 文中展示了一个具有创新性的新闻可视分析系统——VASNRU.该系统有机地结合了新闻数据收集与可视分析,旨在帮助用户更好地分析与理解新闻数据.该系统首先根据用户想要查询的内容,利用搜索引擎自动地收集一定数量的新闻数据;在此基础上,自动地对收集到的数据进行预处理,以便进一步进行分析.为了帮助用户更好地分析与理解数据,采用一个可视分析工具(Mutual Ranker)对处理好的数据进行可视分析,采用VASNRU收集并分析了2个真实的新闻数据集,结果验证了其能够方便、高效地收集与分析新闻数据.

     

    Abstract: In this paper, we introduce a novel visual analysis system called VASNRU(visual analysis system for news retrieval and understanding). It combines news data retrieval with visual analytics to help users retrieve and analyze news data. Given a user-specified query, VASNRU first retrieves a collection of news articles crawled from search engine. Then it automatically pre-processes the retrieved data for further analysis. VASNRU employs a text visual analysis toolkit called Mutual Ranker to support better analysis of the news data. We have used VASNRU to retrieve two real-world news datasets and performed analysis. The results demonstrated the effectiveness and usefulness of our approach to retrieve and analyze news data.
