言語・時間情報による単語照合・訂正に関する研究
Abstract:This document will present the research work I conducted in ATR for five months from
april to august 2002. It will focus on two main directions: word verification and word
correction. The results which will be presented were achieved using the SPINE2
database. My approach to both problems is mainly based on the use of N-best lists
outputted by the recognizer. Concerning word verification, I investigated several
already known word scoring methods and I set a threshold on each one with the equal
error rate method. As for word correction, I combined N-best lists with language
information and other types of useful information. I then created a list of candidates
among which a choice was made using several scoring methods.
