Abstract

Erie is a name recognition system developed for the Multilingual Entity Task (MET) in MUC-6. The pattern matching engine recognizes organization, person, and place names along with time and numeric expressions in Japanese text. Although our previous information extraction system Tex-tract performed well in MUC-5, the pattern matching engine, which was written in AWK language, was slow[2]. System maintenance was also difficult, since the patterns were defined in both the matching engine and the pattern files. Erie solves these problems by generating a pattern matching engine in C language directly from the defined patterns.
