Automated Subcategorization of Named Entities.
Michael Fleischman · 2001
There has been much interest in the recent past concerning the possibilities for automated categorization of named entities. The research presented here describes a method for the subcategorization of location names. Subcategorization of locations is not a trivial task even for human subjects, who perform at accuracy levels of less than 58%. After experimenting with both Bayesian classifiers and decision tree learning algorithms, we have designed a system that achieves accuracy levels greater than 80%.
