Satoshi Sekine, Ralph Grishman, Hiroyuki Shinnou · 1998
This paper describes a system whichusesadecision tree to ndandclassify names in Japanese texts. The decision tree uses part-of-speech, character type, and special dictionary information to determine the probability that aparticular type of name opens or closes at agiven position in the text. The output isgenerated from the consistent sequence of nameopens and name closes with the highest probability. This system does not require any human adjustment. Experiments indicate good accuracy with asmall amount of training data, and demonstrate the system's portability. Theissues of training data size and domain dependency are discussed. 1
