Kevin Burton’s NEW FeedBlog

Yet another entrant into the competitive blogsearch space as Ask.com launches their own blog and feed search engine.

The same engine is also deployed within Bloglines (another Ask.com company).

Techcrunch makes a interesting comment on their relevance algorithm.

There is a big need for the equivalent of Google Page Rank for blog search relevance. Link analysis on a post just doesn’t work – the content is too fresh to develop meaningful link analysis results. There are now three experiments going on with relevance: Technorati bases relevance solely on “authority” of the blog, which is calculated solely on unique inbound links to the blog itself.

Of course PageRank is just a form of link analysis. Simple indegree based analysis obviously doesn’t work. We’re working on some new stuff for Tailrank to include additional content specific semantic analysis which should be a lot more fine grained and smarter with newer content like blogs (seems like Sphere is aiming to do this as well).
