Abstract:


Designing visual interfaces to layout and visually explore large
document collections still remain a focus of attention. This task can
be tackled using various techniques, typically combining Euclidean
embedding's (MDS, graph drawing) and document clustering. The
complexity of this task produces results of varying quality and
inevitably carries noise. At any rate, users must be careful when
interpreting Euclidean proximity or grouping of documents. We address
this problem by computing a relevance feedback index for any group of
documents (selected by the user, or forming a cluster)
confirming/infirming whether a group of documents can be trusted to
form a semantically coherent unit. The index is inspired from past
work by Ronald Burt -- document visualization meets social network
analysis.
