Sound Index övervakar vad du lyssnar på, på ett bra sätt

\n\t\tEvery six hours the Sound Index crawls some of the biggest\n\t\tmusic sites on the internet - Bebo,\n\t\tMySpace,\n\t\tLast.FM,\n\t\tiTunes,\n\t\tGoogle and\n\t\tYouTube - to find out what\n\t\tpeople are writing about, listening to, watching, downloading and\n\t\tlogging on to. It then counts and analyses this data to\n\t\tmake an instant list of the most popular 1000 artists and\n\t\ttracks on the web. The more blog mentions, comments, plays, downloads\n\t\tand profile views an artist or track has, the higher up\n\t\tthe Sound Index they are. So, the Sound Index is a music\n\t\tbuzz index controlled entirely by the public.

The Sound Index trial has been co-funded by both BBC Public Service and BBC Worldwide, as both were interested in investigating the semantic search and processing listing model. All running costs have been split between both IBM, whose Semantic Super Computing is used to crawl and analyse our partners' sites, and NovaRising who render the data and produce the front-end. The costs have included ongoing development as well as maintenance and hosting.
