We propose a method for the structural analysis of Web documentation. Employing the non-well-founded set theory, we have developed a means of reduction analysis to detect irregularities in the structures of target documents. To test this method's effectiveness, we applied it to Web-based educational materials in actual use and succeeded in identifying(More)

The system suggests the level of difficulty of a reading material for a student and generates a personalized glossary. We developed a prototype system based on this concept. The reading material is expressed by a word set and is operated by utilizing set operations in the(More)

The web-based program was designed to identify the distribution of vocabulary items from General Service List, Academic Word List, and JACET 8000 (4000+250) in a(More)
Recurring patterns of the same link structure can often be observed on Web sites. Patterns are important for site administrators in revising Web sites but are difficult to find empirically. We propose a method for detecting such patterns. The first step in the method is viewing a Web site as a directed graph, and identifying pages that have the same(More)
