Abstract

The data extraction systems studied in the MUC-3 evaluation perform a variety of subtasks in filling out templates. Some of these tasks are quite complex, and seem to require a system to represent the structure of a text in some detail to perform the task successfully. Capturing reference relations between slot fillers, distinguishing between historic and recent events, and many other subtasks appear to have this character.
