| Research Abstract |
At the beginning of our research, we were planning to use two indices of recall and precision in order to measure a similarity between an input answer and the model answer. After that, it turned out that use of the textual entailment recognition based on the legitimate natural-language-processing technology is promising. Our research was advanced, acquiring knowledge from the member of National Institute of Informatics. Main results are follows:
(1) Evaluating or grading essays based on our actual proof experiment was announced at the 10th Japanese Test society convention. (2) About the computer use and automatic grading in an essay or composition test, a lecture was given at open symposium to introduce our activity widely. (3) The method of the statistical technology towards automatic grading was developed, and many papers were published in famous journals.
