General information

Abstract

ChemFOnt (the Chemical Functional Ontology) is a hierarchical, OWL-compatible ontology describing the functions and actions of more than 341,000 biologically important chemicals. See more...

Description

ChemFOnt contains data on 341,627 chemicals, including 515,332 terms or definitions. The functional hierarchy for ChemFOnt consists of 4 functional “aspects”, 12 functional super-categories and a total of 173,705 functional terms. In addition, each of the chemicals are classified into 4,825 structure-based chemical classes. ChemFOnt currently contains 3.9 million protein-chemical relationships and ~10.3 million chemical-functional relationships. The long-term goal for ChemFOnt is for it to be adopted by databases and software tools used by the general chemistry community as well as the metabolomics, exposomics, metagenomics, genomics and proteomics communities. As noted earlier, the 4 functional "aspects” are divided into 12 function super-categories which are further subdivided into another 399 functional subcategories which are further divided into thousands of other branches or leaf nodes for a maximum depth of up to seven layers. In particular, Physiological Effect has 3,637 defined categories; Disposition has 4,186 defined categories; Process has 161,098 defined categories; and Role has 1,037 defined categories. In total, ChemFOnt has 173,305 fully defined and fully connected functional categories, which are all placed into a logically consistent hierarchy. See more...
