| Research Abstract |
In this study, we established a method for comprehensive term extraction from domain text corpora with high precision. The method is based on basically two new principles. One is the reconsideration and modification of Japanese morpheme classification, and another is the evaluating the certainty of composite boarders. We also have developed methods to structurize terms from two points of view, namely, nesting relations between composites, and the term relationships to various research subdomains.
