Centering as an Anaphora Generation Algorithm: A Language Learning Aid Perspective.
Mitsuko Yamura-Takei, Miho Fujiwara, Teruaki Aizawa · 2001
This paper describes our attempt to de-velop an NLP-enhanced CALL program for Japanese learners. This CALL pro-gram focuses on zero anaphora acquisition. Based upon our previous work (Ya-mura-Takei et al., 2001), this paper will analyze the revision-based zero anaphora generation task. We first discuss the problems students face in treating zero anaphora by providing some empirical data from a language classroom. We then propose an anaphora generation al-gorithm within the Centering framework and evaluate its feasibility by comparing the algorithm output with human judg-ments. The evaluation result provides insights for the empirical validity of the algorithm and its future extensions.
