General information
Name | Faceted Classification Scheme (FCS) |
---|---|
Problem | Ontological representation of a specific domain concept conceptualized using a Faceted Classification Scheme (FCS). |
Non-Ontological Resource
Description | A FCS is defined as: "a set of mutually exclusive and jointly exhaustive categories, each made by isolating one perspective on the items (a facet), that combine to completely describe all the objects in question, and which users can use, by searching and browsing, to find what they need" (Denton, 2003).
The following notation is introduced to refer to the elements of a generic FCS in the figure below:

Ontology
Description | Generic structure of the Normalization ODP used to represent a Faceted Classification Scheme.
The symbol (≡) denotes an OWL defined class. The figure below represents a further generalization of the Normalization ODP and introduces the following notation:

Process
Description | Mapping between the elements in the generic structure of a Faceted Classification Scheme and the Normalization ODP.
The table below summarizes the alignment of the elements in the generic structure of both conceptual models. This alignment enables the conversion from a FCS to an OWL DL ontology by applying the Normalization ODP:
as introduced in section Ontology above.
Based on the principle of representating each facet of a FCS as a module of the Normalization ODP, the underlying ideas behind the mappings in the figure(table) above can be outlined as follows:

Scenario example
Description | To create an ontology model to represent an existing Faceted Classification Scheme for a specific domain concept. |

Example of a Non-Ontological Resource
Description | The figure below recaps the final FCS developed for the "Dishwashing Detergent" domain example in (Denton, 2003)(§ 2.4). The elements of the schema fit into the generic structure of a FCS presented in section Non-Ontological Resource earlier, where:

Multiple Alternative Classification Criteria | Allow me to retrieve all "elements" (classes/individuals) of a "domain concept" viewed by a combination of "values" (or "terms") from various "classification criteria" (or "facets"). | |
View Inheritance | For example in the case of the representation of the "wine" domain concept:
In the case of the representation of the "pizza" domain concept:
