ELLERDALE

Ellerdale, operating in stealth mode for most of the past year, has built an exciting site using leading-edge semantic technology that filters the real-time stream by topics, instead of keyword strings. This enables Ellerdale to automatically display trending topics in real-time within categories, e.g. trending people, trending films, trending companies, trending sports, etc. Users can select from over a million individual topics to track in real-time. The latest tweets and rss articles are tracked, as well as the most discussed URLs that match the topic. The reason Ellerdale is able to do this is that they index the stream using richly described topics that belong to categories, instead of the usual approach of relying on simple keyword strings.
