    Thanks, these are interesting links.  I especially like figures 13, and 14 or this paper:
            TOPIC ISLANDS [TM] - A Wavelet-Based Text Visualization System  http://www.pnl.gov/infoviz/vis98paper.pdf
    which "show the interplay of theme map and the narrative".  This method of using arrows to show logical flow could be useful for graph-based discussions.

    Something that specifically interests me about ewall, however, is that it is not a post-hoc visualization.  Rather it relies on the users to organize the information themselves:

    A3. Diverse data formats
    What computation is necessary to allow decision-makers to directly operate with different types of static and dynamic data formats?
    EWall’s objective is to allow decision-makers to collect, organize and evaluate static and dynamic data types independent of its format.

    The 'decision-makers' are the ones that are organizing the data, not the software ( Or at least that's what I gather from the scant amount of information available )

    "Battelle / Pacific Northwest National Laboratory (PNNL) is developing a multi-resolution wavelet-based methodology, called TOPIC-O-GRAPHY(TM), to decompose long natural language documents into thematically coherent and hierarchically-related sub-pieces. The concept is to exploit the hierarchical nature of typical discourse to produce visualization and analysis tools that permit the information contained in long documents to be more quickly identified and absorbed.

    In prior TOPIC-O-GRAPHY work, basic concepts were developed and demonstrated on individual test documents. The focus of this project is to improve the mathematics used in the wavelet processing for longer single documents and to extend the methodology to cross document analysis. The basic research will be showcased by a suite of visualization and analytical tools promoting highly interactive information exploration, summarization, and retrieval."

    Also, TOPIC-O-GRAPHY is a project funded by DARPA's Intelligent Communicator Collaboration & Visualization project for emergency information management for situation analyses (see my e-mail on 9/18/01 about Visual Presentation Methods). 

    Visual Presentation Methods 
We have found that visualizations can provide a powerful method to communicate the salient
features of the information, using methods that are natural for the human mind to perceive and
understand. As an example, one visualization method for showing an overview of relationships
among documents is a cluster projection in two or three dimensions, where proximity indicates
similarity. The Galaxies visualization shown in the first figure is an example of such a 2D
visualization. Documents are clustered according to similarities in their thematic content.
Interactions allow the user to query for particular terms, form groups, and see changes over
time."  more ... , including screen captures of of several visual presentation methods
