We have made some new features available on PolyMeta.com.
On one hand, if somebody searching in the news category PolyMeta groups news items with identical titles together, and shows a link next to the link of the item: Show more with this title. It can eliminates a lot of duplicate news items.
On the other hand, we are showing source clusters under the topic clusters, in each search category, what makes very easy to filter our results for a particular source after search in the web, news and blogs categories.
Check it out on PolyMeta!
