The Gellish English Dictionary-Taxonomy is an example of an open-source “smart” electronic dictionary, in which concepts are arranged in a subtype-supertype hierarchy, thus forming a taxonomy. The dictionary-taxonomy is machine readable. It is compliant with the guidelines of ISO 16354. Apart from the fact that it is an English (business-technical) dictionary, it also defines the semantics of Gellish English, which is a computer-interpretable structured subset of the natural English language for data storage and data exchange. The dictionary-taxonomy differs from conventional dictionaries because of several additional capabilities. Therefore it is called "smart." This means that it satisfies the following criteria:
The phrase "is a part of" is a standard phrase for composition relations that can be used to express facts that relate parts to wholes. The other standard phrase "can have as part a" is a phrase for a concept that can be used to express knowledge that a whole of a particular kind can have as a part a component of a particular kind. The "shall have as part a" relation is intended to be used to express requirements. All phrases have also inverse expressions, such as "has as part" and "can be a part of a," which denote the same concepts (relation types), but which require an inverse sequence of the related objects. The following table illustrates the use of these relation types in Gellish English expressions.
Note: All elements in the last two expression above (pump, can/shall have as part a, and bearing) are "names" of standard English concepts that are defined in the Gellish English Dictionary-Taxonomy or a proprietary extension, such as for "pump type A."
The Gellish English Dictionary-Taxonomy is available as a collection of standardized Gellish Data Tables. Each of those tables has the same standard column definitions. Thus the whole dictionary-taxonomy can be treated as if it were one table.
