A Two-Level Adaptive Visualization for Information Access to Open-Corpus Educational Resource

Abstract
The labyrinthine abundance of educational resources on the Web has
greatly expanded the challenge of helping students find, organize, and use resources
that will best match their individual goals, interests, and current knowledge.
Map-based navigation, using technologies such as the Self-Organizing
Maps (SOM), is one solution to this growing challenge. However, as the number
of documents organized by SOM increases, the number of documents
within each cell becomes too large for the user to make meaningful choices,
overwhelming his ability to make accurate decisions. Combining interactivity
with the ability to organize a large number of documents, we have developed
two-level heterogeneous maps that are augmented with social navigation support.
We implemented our idea within the Knowledge Sea II system and ran a
pilot study using this system in an Information Retrieval course.
