Contextual modeling of collective diagnosis of chronic inflammatory bowel
Main Article Content
Abstract
The paper presents results on the modeling of contextual reasoning of Anatomy and Cytology Pathologists in chronic inflammatory bowel disease diagnosis. The diagnosis is modeled in the Contextual-Graphs formalism that offers a uniform representation of knowledge, reasoning and context. The diagnosis is considered as a mental model that is extracted of a mental representation expressing pathologists’ experience on this diagnosis. Building and development of the mental model are intertwined during the contextual nonlinear reasoning held during diagnosis. Modeling of contextual reasoning is particularly relevant for decision-makers that cannot work on formal model. The Contextual-Graphs formalism was applied in several domains, including medicine, for different aspects of cancer (breast, lung, prostate) and at different levels from a synthesis on breast cancer diagnosis to mitosis identification on digital slides, the modeled diagnosis here being between them.
