概要:

This study examines the similarities of documents by text mining.

Here, the documents are syllabuses from the department of electrical and computer engineering in National Institute of Technology, Gifu college.

The results will help motivating students to learn.

To calculate the degree of similarity, the following methods are adopted to our school's syllabuses.

The procedure is as follows.

1. Use direct term matching method.
2. Use Latent Semantic Analysis.

The syllabus in which rubric is added in 2015 is used in this study.

The degree of similarity is calculated with or without compound words and importance of words. This calculation of similarity is evaluated against the courses system diagram.

Next, the same evaluation is carried out with binarization of similarity.

As a result, it turned out that the result with binalization of similarity is better than the one without it.
