New York University PROTEUS system: MUC-3 test results and analysis

چکیده
Although the template specifications call for us not to produce templates for non-specific event descriptions, ou r base run did not attempt to filter out such descriptions, in part because the criteria are hard to specify, but mainl y because at our low recall there was a fair chance of missing date or perpetrator information and thus eliminatin g templates incorrectly . However, we made two optional runs to attempt to eliminate these templates . For both runs , we eliminated all military and terrorist targets (we had found from our training runs that these targets were frequently being incorrectly combined with civilian targets and therefore emitted as parts of templates) . For the firs t run, we then eliminated all templates with neither perpetrator nor targets (typically arising from nominalization s such as "the recent attack", when there was no preceding attack being referred to) ; the results were :

Evaluating the degree of improvement over the MUC-3 runs is complicated by the changes between MUC-3 an d MUC-4: there were changes in the template structure, the MURDER templates were eliminated, content mappin g constraints were incorporated into the scoring program, and the rules for manual remapping were much more con strained. We resumed system development specifically for MUC (with regula...

Through the history of the MUC's, adapting Information Extraction (IE) systems to a new class of events has continued to be a time-consuming and expensive task. Since MUC-6, the Information Extraction e ort at NYU has focused on the problem of portability and customization, especially at the scenario level. To begin to address this problem, we have built a set of tools, which allow the user to ...
