基于Android的个性化RSS订阅系统的设计与实现
摘要
移动互联网发展到今天并伴随着安致等智能手机操作系统出现,我们已经进入了一个移动网络高速化、信息海量化的时代。使用丰富站点摘要(RSS,Rich Site Summary)订阅系统不需要直接去各个门户网站进行信息的搜索,因此解决了用户打开众多网页的麻烦。而且,RSS订阅系统会定时更新,使得信息不能及时更新的问题得到了很好的解决。但是,由于各个网站报道的新闻内容很多是相似的,用户因此订阅了很多重复的信息。
针对现有的RSS阅读器当用户同时订阅很多网站信息时会存在大量重复信息的缺点,本系统将改进现有RSS阅读器功能,实现个性化订阅。这些个性化的功能分别是相同或相似内容新闻过滤功能,即当订阅的网站出现相同或相似的新闻时仅显示用户最想看到的新闻;选择订阅功能,即用户设置的订阅关键词或禁止关键词后,优先显示用户订阅的新闻不显示禁止的新闻以及收藏夹功能,即可收藏自己感兴趣的新闻。
本系统开始先从RSS网站取得RSS文件并通过解析模块进行解析,然后通过中文分词算法对解析出的新闻标题进行中文分词,并将分词结果作为该新闻的关键词。最后按照用户对RSS源优先级的设置过滤重复新闻,显示优先级最高的新闻即用户最想看的新闻;如果用户设置的订阅或禁止显示的关键词,则要优先显示用户订阅的新闻,不显示禁止的新闻。
通过引入准确率和召回率以及F值的评测指标,将系统运行结果加以详细的统计和对比分析,系统满足当初的设计要求,能够为用户提供个性化订阅服务,因此认为得到了较为理想的结果。
As for mobile internet development and the smart mobile phones operating system about the Android appeared, we have entered a high-speed mobile network, the quantification of the information era. Using RSS(Rich Site Summary) reader does not need to go straight to the website for information searching and thus solve a user’s trouble that user needs to open a lot of webs. RSS subscription system will regularly update, which provides a solution to the update problem. However, a lot of sites contain similar news, so a lot of information is subscribed by the user.
For an existing RSS reader, there is much duplication of information shortcomings, the system will improve the existing functions, implement personalized subscribe. These customized features are deleting news that have the same or similar content (when the subscription web site that is the same or similar news, it shows only the news which user wants to see), selectively subscription (it only shows subscription news that are set by the user) and favorite (user favorites news which is interest to by user).
Firstly, this system obtains RSS documents from RSS web site and parses module. Then, tag keyword from the title of news analyzed by using the Chinese word segmentation. Finally, in accordance with priority which is set by user, implement for filtering news and show the highest priority news. If user set keyword, firstly show new which is subscribed by user, and don’t show new which is forbidden by user.
Import the value of P and R and the evaluation parameter and run the system to be detailed statistics or comparative analysis. System achieves the original design. It can be able to offer individualized subscription service. So a good result is achieved.
