Introducing the case grammar concept to object-oriented movie context description

The movie based context-aware language learning system shows the movie to learners and generates quizzes and expected answers along the movie from the movie context description prepared in advance. The movie context description should have enough descriptive power that can represent movie scenes well. This paper integrates the case grammar concept, which is known in the field of natural language processing, into object-oriented context model to describe the movie context that the authors presented in the previous work. Through trial context description based on ninety-eight English sentences, it is found that the revised object-oriented context model with the case grammar concept helps writers describe movie contexts without confusion due to unnatural interpretation as observed in the previous model, especially to describe dynamic things.
