Fig. 1From: Finding semantic patterns in omics data using concept rule learning with an ontology-based refinement operatorAn example of partial-order binary relation ≽ over a set of terms T. The partial-ordered set is depicted in the form of a Hasse diagram. The terms and relations come from Gene Ontology. Elements in curly brackets represent examples that are associated with the individual terms according to the mapping S. In other words, the information about associations between examples and terms captured in the mapping M′(t) has already been hierarchically spread over the whole ontologyBack to article page
