Initial work in dynamically creating a class hierarchy of Typical Absence Seizure subtypes using FCA. (A) Shows the two-dimensional matrix of attributes and epilepsy types used as input to FCA, (B) illustrates the concept hierarchy (lattice) with higher-level relationships that are often not apparent from the lower level classification, such as the fact that Eyelid Myoclonia with Absences is a subtype of Typical Absence Seizure, and (C) shows the construction of an ontology class hierarchy from the concept hierarchy.
