Comparing MUCK-II and MUC-3: Assessing the Difficulty of Different Tasks
Abstract
The natural language community has made impressive progress in evaluation over the last four years. However, as the evaluations become more sophisticated and more ambitious, a fundamental problem emerges: how to compare results across changing evaluation paradigms. When we change domain, task, and scoring procedures, as has been the case from MUCK-I to MUCK-II to MUC-3, we lose comparability of results. This makes it difficult to determine whether the field has made progress since the last evaluation. Part of the success of the MUC conferences has been due to the incremental approach taken to system evaluation. Over the four year period of the three conferences, the domain has become more "realistic", the task has become more ambitious and specified in much greater detail, and the scoring procedures have evolved to provide a largely automated scoring mechanism. This process has been critical to demonstrating the utility of the overall evaluation process. However we still need some way to assess overall progress of the field, and thus we need to compare results and task difficulty of MUC-3 relative to MUCK-II.
