Abstract
Constellation is a visualization system for the results of queries
from the MindNet natural language semantic network. Constellation is
targeted at helping MindNet's creators and users refine their
algorithms, as opposed to understanding the structure of language. We
designed a special-purpose graph layout algorithm which exploits
higher-level structure in addition to the basic node and edge
connectivity. Our layout prioritizes the creation of a semantic space
to encode plausibility instead of traditional graph drawing metrics
like minimizing edge crossings. We make careful use of several
perceptual channels both to minimize the visual impact of edge
crossings and to emphasize highlighted constellations of nodes and
edges.
