Description of the Oki System as Used for MUC-7

This paper describes the Oki Information Extraction system as used for MUC-7 evaluation [1][2]. The tasks we have conducted are Named Entity, Co-reference, Template Element and Template Relation. Each module is implemented using MT system modules and pattern recognition modules. Our purposes to participate MUC-7 evaluation are to evaluate howMT system modules are e ective for other application such as IE system and to develop our information extraction technology based on pattern recognition.
