Sum

Knowledge base is organized by sets of facts.Sometime it can be interesting to sum these graphs. Example below presents two graphs first contains geographical informations,second contains informations about flavor and sweetness.

graph1

graph2

Cogui provides a wizard to sum graphs. It consist in merging graphs into the same sum graph.
the resulting graph is shown below :

Normalize

We obtain a sum graph which is not a normal simple graph. A normal SG is such that each concept is uniquely coreferent with itself. Note that an implicit coreference link exists between the two nodes representing the individial vin:CorbansPrivateBinSauvignonBlanc. Normalization performs the fusion of nodes associated to the same individual. See below the normalized sum of graph1 and graph2. Resulting graph give an answer to query above.
 

Add individual graphs

An individual can be associated with a graph containing some implicit knowledge about it. Sum assistant present an option to also add these individual graphs when individuals occurs in selected set of graphs. See this chapter for more informations about individual graphs.

Use Assistant

A tool to sum and normalize graphs is provided by Cogui. Choose "Reasoning/Sum and normalize facts" menu option to run the wizard displayed below:

Resulting graphs can just be edited from the result view. Two ways exist to add this graph to the knowledge base. Assistant panel propose an option to directly add the graph to the knowledge base. Another way is to drag graph from the result view to the project tree view.
