Supporting Knowledge Capture, Construction, and Sharing

Concept maps capture knowledge about the concepts and concept
relationships in a domain, using a two-dimensional visually-based
representation. Computer tools for concept mapping empower novices
and experts to directly construct, navigate, share, and criticize rich
knowledge models. This talk describes ongoing research on augmenting
concept mapping tools with systems to support the user's knowledge
construction process by proactively suggesting relevant concepts and
associated resources (e.g., images, video, and text pages) during
concept map creation. Providing such support requires efficient and
effective algorithms for judging concept similarity and the relevance
of prior concepts to new concept maps. We discuss key issues for such
algorithms and present initial approaches to estimating similarity and
relevance of new information. We close by discussing their tradeoffs and
new research challenges.
