Content Curation World

Defcomb is a new interesting web app, which while in full development, already offers some valuable features for anyone interested in monitoring and analyzing specific topics.

The app, which is fully free as of now, allows you to: 

1) Add your selected RSS feeds, OPML file or to tap in Defcomb extensive global archive of feeds to determine your content sources. 

2) Determine keyword-based filters by grouping multiple keywords

into sets.

3) Generate a news feed from your selected content sources filtered by anyone of your keyword sets or their combinations.

4) Publish a public RSS feed for each one of your news feeds.

5) Visualise occurrences of your specified set of keywords inside your sources across time

Applications for this tool may include personalised news and content discovery, topic tracking, text mining and data-visualisation.

N.B.: For novices, watch out. This tool is not difficult to use, but it may not so intuitive the first time around. Best thing to do to avoid wasting any time is to watch the short screencast video available on the home page (is video-only, no audio) and to read this short tutorial:
