Topsy is designed to mine the collective signal from the social web in real-time. To measure the relative importance of each search result, Topsy examines the links being cited, the description of these links and the influence of each person citing a link. Topsy augments traditional search engines by finding interesting and relevant information that people are talking about. If other people are discussing it, Topsy thinks you might find it interesting and relevant too!
“Search powered by the social web” is a simple phrase, which hides many interesting problems. Topsy’s approach is an attempt at solving these problems with a range of new technologies – and initially, a dataset based exclusively on the conversations taking place in the wonderful Twitter community.
