The Session track has two primary goals: (1) to test whether systems can improve their performance for a given query by using previous user interactions with a retrieval system (including previous queries, clicks on ranked results, dwell times, etc.), and (2) to evaluate system performance over an entire query session instead of a single query.
The TREC track has focused on the first goal. The purpose of this site is to evaluate the second goal by simulating user interactions with ranked results.
