New search engine Topsy, which has been in stealth development for three years, is launched. AltaVista determined relevance based on how well a web page matched the query. Then came Google, which views the web as a network of documents and delpoyed its PR algorithm. Today all search engine determine search be linking behaviour.
Now web is changing and real time content is being created, Google and other SEs cannot keep up with that real time content. That’s where Topsy comes in. Topsy lets you search through what people are saying about things. Topsy sees the Internet as a stream of conversations between people. It ranks each search result based on how much people are talking about it, and the influence of the people discussing it.
