VAC Weekly Highlight 3/26/08

This is a reprint of the Visual Analytics Centers (VAC) weekly email highlight distributed by Pacific Northwest National Laboratory to VAC partners and supporters.

VAC Students Rock the House at the DHS UP Summit

VAC students presented 15 of the approximately 40 posters at the DHS University Network Summit. All were exceptional and they showed the commitment the VACs have toward educating the next generation of scientists.

For the second year in a row, a VAC student took first place in the DHS University Summit poster competition -- this year to Don Pellegrino from Drexel for his poster on Automatic hypothesis generation and evaluation by network structure content analysis and visualization. In the poster, Don introduces his Semantic Network Structure Analysis (SemanticNetSA) tool. SemanticNetSA is designed to enable analysts to find meaningful patterns in previous analyses and apply those patterns to the discovery of similar themes in new data. The core research questions behind Don's work are: (1) Can objective interestingness measures identify patterns of relations that serve as useful initial hypotheses? (2) How should patterns of relations be captured to support reuse in hypothesis formulation? (3) Can visual navigation of graphs support evidence based evaluation of hypotheses?
