Abstract
The objective of this paper is to analyze the temporal structure of a sequence of sentences. As the target of this analysis, we consider cooking recipes. The recipes are considered to be typical examples that prescribe the temporal relations of affairs. However, it seems very difficult to understand the temporal relations without our common knowledge. In order to do this analysis, we utilize aspectual information of each activity. We reclassify aspects, considering the affairs which are specific to cuisine, and define subclasses of perfective aspect. In addition, to enhance the adequacy of analysis, we consider adverbial information, elliptical expressions, and concurrent operations. we design and implement the automatic generation system of ‘time map’ for the cooking recipes.
