Introductions to Conceptual Graphs

Conceptual Graphs Standard NotationCurrent StandardThere is a standard for the Conceptual Graphs Interchange Format (CGIF). This standard was developed in conjunction with the ISO Common Logic Project, which seeks to standardize a form of logic for knowledge interchange, and includes three syntaxes for Common Logic, one of which is CGIF in Annex B. Comments and suggestions on the entire standard are welcome; see the web site for more details. Earlier ProposalsHere are some documents that may be of some historical interest. Note that CGIF has undergone significant changes from these documents; see the current standard (above). A very old draft proposed (c. 1998) for conceptual graphs: |

ToolsAmine - a multi-layer platform dedicated to the development of Intelligent Systems and Multi-agent Systems. CharGer - a prototype conceptual graph editor developed at the University of Alabama in Huntsville, free for noncommercial use, and runs under Java. CG Mars Lander - fast conceptual graph retrieval and question answering tool, available for joint development and industrial funding. CoGITaNT - several useful utilities: a set of library routines in C++ for conceptual modeling, some knowledge bases in conceptual graphs, and an XML specification for CGXML. CPE - a modular environment that provides modules to give functionality to a user without having to take the whole environment. Currently, there is a CGIF editor, ARCEdit and other CG Operations (Projection and Maximal Join) should be available in the future. GoGui - a free graph-based visual tool, developed in Java, for building Conceptual Graph knowledge bases represented in COGXML format, compatible with CoGITaNT (see above). Prolog+CG - an object-oriented extension of PROLOG, based on CG. CG (both simple and compound) is a basic data structure, like term. PROLOG+CG is implemented with Java. WebKB - tools for information retrieval and knowledge representation. At ICCS'05 in Kassel, Germany, a discussion was held about how to further the progress of CG tools. Here is a summary of the discussion. |
