CoGui is a graph-based visual tool for building Conceptual Graph knowledge bases encoded in COGXML. In order to build / edit your knowledge base you need to build / edit (1) the vocabulary and (2) the facts.

- To build / edit your vocabulary click on Project (left panel) and then double click on Vocabulary. You will then be able to build or edit the concept or relation hierarchies as well as the set of individuals.
- To build or edit the fact graphs select Project (left panel) and then double click on Facts. Right clicking on Facts will allow you to create a new set of facts and then a new fact. To edit a fact simply double click on it.
- To query facts, using COGITANT as a querying engine, create your query (Project > Queries) then use the Query facts assistant (Reasoning menu).
- To enhance your knowledge base with rules select Project (on the left) and then Rules.
- Several assistants for processing facts and rules are available from the Reasoning menu.
