CG Tool Information




A graphical editor for conceptual graphs.


Java 2 (JDK 1.2.2). Tested under Windows 2000, MacOS 9.1 (MRJ 2.2.5) and Linux 2.2 (RedHat 6.0).

Compliance with CGTools CGIF final graphs


Charger uses the parser from the Notio API version 0.2.2 and its compatibility is no greater than that version. Type and relation lattices are not parsed.


CharGer enforces some built-in actor definitions, as defined in the user's guide. CharGer's matching facility is incomplete; it is based on Notio's matching scheme, but is not fully tested. Coreference set semantics (e.g. nesting rules) are enforced according to Notio's interpretation. No type, relation or actor definitions are supported. Negation (i.e. "neg" relation) has no special interpretation.
