The TREC 2001 QA track had an additional task call the list task. In the list task, the questions specified a target number of instances to retrieve and the response was an (unordered) list of no more than that many items. For example, one question in the task was "What are 9 novels written by John Updike?", and the response was to be the titles of 9 Updike novels. The list task requires a *set* of answers to be judged as a whole; thus there is not the equivalent of a main task judgment set or pattern set for this task. The "original answers" file below contains a list of the answers the assessors found as they were creating the questions.
