ReadWriteWeb has posted an article on the 10 best Semantic Web products of 2008. The top two spots are taken by Yahoo and Microsoft. Yahoo! SearchMonkey is a search platform aiming at making the search better by leveraging web annotations. Microsoft acquired Powerset, a natural language processing search engine. Who has not made the list and maybe they should have: Twine by Radar Networks, which provides a new way of tracking, finding, and sharing content, all in one place.
