quite frankly blows everything, and I mean everything, Iâ€™ve seen out of the water in terms of relevance (and, by the way, designâ€¦Adaptive Path was involved).
Sphere’s search tackles the thorny issue of relevance by having
an analysis of links into and out of a blog, an analysis of metadata around a post (links, post frequency, length of posts, etc.), and something Tony calls their â€œsecret sauceâ€?, which is content semantic analysis to filter out spam and to understand what a blog post is talking about.
show only two posts per blog on the first page, so no one blog can dominate a category. The result set has auto-generated profiles of blogs that include recent links in and out of the blog, average posts per week, average words per post and a link to a full page profile that can be edited by the blog author.
Sphere has apparently been indexing blogs since January 2003 so you would imagine they have a fairly comprehensive database to start from!
