Overview - Question Answering 2003

Proceedings | Data | Runs | Participants

The TREC 2003 question answering track contained two tasks, the passages task and the main task. In the passages task, systems returned a single text snippet in response to factoid questions; the evaluation metric was the number of snippets that contained a correct answer. The main task contained three separate types of questions, factoid questions, list questions, and definition questions. Each of the questions was tagged as to its type and the different question types were evaluated separately. The final score for a main task run was a combination of the scores for the separate question types.
