Our QDA software - ATLAS.ti - supports network modeling on semantic and episodic level via user definable sets of relations. Through semantic retrieval (and relation properties like transitivity), you may yield all constituents of a proposition. In addition, rhetorical structures can be represented on the data level via named hyper links. So it fits a number of approaches like action theory, grounded theory or argumentation analysis quite well. However, there is some drawback with all such representation techniques if used beyond browsing or "heuristic" mind mapping. They look really pretty for trivial examples but can get quite complex and loose some of their expressive power when it comes to modeling real world episodes. Here is a textual output of a network fragment from ATLAS.ti with both semantic and episodic knowledge representing different interpretations of the "birds" ("Millers saw the cranes when they were flying over the alps") example: Action_x <agens>: Agent_x <instr>: Instrument_x <loc>: Loc_ationx <objekt>: Object_x <recip>: Recipient_x <time>: Time_x fly_over_1 <loc>: Alps <instance-of>: fly_over <agens>: Millers <instr>: Plane_1 <time>: Time_x fly_over_2 <loc>: Alps <agens>: Cranes <instance-of>: fly_over <instr>: Self_1 <time>: Time_x Human Being O: Living Thing -<instance-of>: Millers Living Thing -O: Bird -O: Human Being The graphic network looks a little better but would make this mail a little larger!-) - Thomas Muhr At 15:37 14.04.2003 -0400, you wrote: >I'm looking for software that supports coding and qualitative analysis with >conceptual graphs (CGs).
