Applying Euler Diagrams and Venn Diagrams to Concept Modeling.

This article introduces Euler diagrams and Venn diagrams as business analysis instruments. Application of these visual schematics to support development of vocabulary and concept models can help business analysts deal with the complexity of relationships between concepts. It also can help contributing subject matter experts overcome a perplexity commonly observed with intricate aspects of concept modeling. Visualizing typical relationships between concepts with circles that include, exclude, and intersect each other results in simple visual schematics that assist in conducting concept analysis and modeling activities. An implementation example is provided, based on a vocabulary development in the public health domain of immunization information systems.
