Abstract
The study on aspect in Japanese has evolved from the description of the meaning for each type such as “progressive” or “perfective” into the process of the determination of the aspectual meaning including adverbial phrases etc. In this paper, we consider the meaning of the aspectual markers or adverbs as the indicator of the cognitive process like “zooming” or “focusing” on the time-line and define them as the dynamic operations on the meaning of the verb phrases.We estimate the aspectual meaning of verbs from surface expressions in a corpus and represent them as a bundle of features.To evaluate the result of the experiment, we examined the meaning of si-teiru which is one of the most fundamental aspectual markers, and obtained the correct recognition score of 71% for the 200 sentences.
