According to a study from Tel Aviv, Israel, "This study presents an empirical investigation of online hierarchical repositories of items presented to university students in Web-supported course websites, using Web mining methods. To this end, data from 1747 courses were collected, and the use of online repositories of content items in these courses was examined."
"At a later stage, courses with a significant repository size (15 files or more) were analyzed using clustering algorithms in order to reveal hierarchical structures and to identify associations between these structures and course characteristics. suggest five types of structures and some statistically significant differences between them regarding the researched variables," wrote A. Hershkovitz and colleagues, University of Tel Aviv.
The researchers concluded: "A discussion of these results is provided below."
Hershkovitz and colleagues published the results of their research in Internet and Higher Education (Types of online hierarchical repository structures. Internet and Higher Education, 2011;14(2 Sp. Iss.):107-112).
