Participants will be given queries sampled from a web search query log provided by the Yahoo Webscope program, and have to try to answer those queries using the Billion Triples Challenge corpus from 2009. The queries that are selected are all entity queries in that they are looking to find information about a single entity.This is an interesting competition because it attempts to use unstructured web queries to do retrieval over a heterogeneous collection of structured data. The Billion Triples collection contains data from DBpedia (extracted from Wikipedia), Geonames, a variety of social networks, and other sources.
There's a group of us here working on an entry; we'll see how it goes.
