I've been using Liferea [1] for years, and while it doesn't do automated content analysis, it does allow you to group feeds into folders, then get an aggregated view of the folder as a whole. It also allows "search folders", which are saved cross-feed searches that are exposed through the same folder interface. I use Liferea as my desktop client, but with TT-RSS running on my VPS as the underlying data source.
