Interfaces for Intense Information Analysis Marti Hearst UC Berkeley This research funded by ARDA Outline A contrast Search vs. Analysis Goals for three user groups Intelligence Analysts Biomedical Researchers Investigative Reporters Our current interface design Search vs. Analysis UIs for Search vs. Analysis Search: A necessary but undesirable step in a larger task UI should not draw attention to itself UI should be very easy to use for everyone Analysis: The larger task UI can be more of a “science project” But UI should have “flow” General Goals Support hypothesis formation / refutation Flow Easy creation, destruction, and cataloging of connections and coverage Easy movement between multiple views Represent: Multiple supporting clues Conflicting evidence Uncertainty Timeliness Non-monotonicity Intelligence Analysts Intelligence Analysts I have recently interviewed several active counter-terrorist analysts Great diversity in Goals Computing environments Biggest problems are social/systemic Many mundane IT problems as well Mundane IT Problems System incompatibilities Data reformatting Data cleaning Documenting sources Archiving materials Intelligence Analysts: Problem 1 Look at a series of reports, images, communication patterns; Try to build a model of what is going on Follow leads Compare to previous situations Recent problem: Groups are changing their behavior patterns quickly Very little use of sophisticated software tools Intelligence Analysts: Problem 2 Given a large collection “Roll around” in the data See what has been “touched” Tools should indicate which parts of the collection have been examined and which have yet to be looked at, and by whom View data in several different ways Data reduction methods such as MDS, SVD, and clustering often hide important trends.
