document: A novel clustering-based RSS aggregator In recent years , different commercial Weblog subscribing systems have been proposed to return stories from users . subscribed feeds . In this paper , we propose a novel clustering-based RSS aggregator called as RSS Clusgator System ( RCS ) for Weblog reading . Note that an RSS feed may have several different topics . A user may only be interested in a subset of these topics . In addition there could be many different stories from multiple RSS feeds , which discuss similar topic from different perspectives . A user may be interested in this topic but do not know how to collect all feeds related to this topic . In contrast to many previous works , we cluster all stories in RSS feeds into hierarchical structure to better serve the readers . Through this way , users can easily find all their interested stories . To make the system current , we propose a flexible time window for incremental clustering . RCS utilizes both link information and content information for efficient clustering . Experiments show the effectiveness of RCS .
