Getting started

In this page we will give a brief introdution into using the CoGui tool. Throughout the document we will use the example "childhood" detailed in the examples section. Please note that this document is intended as a quick overview of the CoGui tool. For further, more in depth explanations, please see the CoGui user guide.

Tutorial

In this tutorial, we present the basic conceptual graph model as well as conceptual graph rules. For each topic, we briefly present theoretical foundations then show how there are implemented in Cogui.

The companion book

This book is the scientific foundation of the software, attempting to answer the following question: "How far is it possible to go in knowledge representation and reasoning by representing knowledge with graphs and reasoning with graph operations ?"

About Us

CoGui implements the Conceptual Graph knowledge representation model, developed by the GraphiK team at LIRMM, Montpellier, France. The team GraphiK is a research group investigating graph-based knowledge representation and reasoning. The originality of their work consists of focusing on formalisms based on labeled graphs (and hypergraphs). By formalisms based on graphs, they refer to formalisms in which knowledge is not only represented by graphs, but where the reasoning mechanisms are also performed by graph operations.
