Abstract:

The goal of the entity track is to perform entity-oriented search tasks on the World Wide Web. Many user information needs would be better answered by specific entities instead of just any type of documents. The track defines entities as typed search results, things, represented by their homepages on the web. Searching for entities thus corresponds to ranking these homepages. The track thereby investigates a problem quite similar to the QA list task. In this pilot year, we limited the tracks scope to searches for instances of the organizations, people, and product entity types.
