A taxonomy minimally includes a description of a domain along class/subclass lines (see <a href="http://sw.opencyc.org/concept/Mx4raaaKviVQEdqAAAACs71DGQ" class="cyc_term">ClassSubclassHierarchy</a>), but can also include other binary relations (e.g., partonomic relations) in its description.

Taxonomy

http://en.wikipedia.org/wiki/Taxonomy ClassSubclassHierarchy The collection of all taxonomic systems that describe a domain only along class (<a href="http://sw.opencyc.org/concept/Mx4rwGWaK5wpEbGdrcN5Y29ycA" class="cyc_term">elementOf</a>) and sub-class (<a href="http://sw.opencyc.org/concept/Mx4rvZA-05wpEbGdrcN5Y29ycA" class="cyc_term">subsetOf</a>) lines. In some circles, only this kind of system is appropriately described as a "taxonomy". class/sub-class hierarchy Cyc Extended System Fn the LSCOM object and situation ontology (CycExtendedSystemFn LSCOMObjectAndSituationOntology) Predicate Taxonomy PredicateTaxonomy TaxonomyOfEasilyUnderstandableConcepts Taxonomy Of Easily Understandable Concepts Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString The collection of all taxonomic systems. A taxonomy minimally includes a description of a domain along class/subclass lines (see <a href="http://sw.opencyc.org/concept/Mx4raaaKviVQEdqAAAACs71DGQ" class="cyc_term">ClassSubclassHierarchy</a>), but can also include other binary relations (e.g., partonomic relations) in its description. A taxonomy can be usefully contrasted with an ontology (see <a href="http://sw.opencyc.org/concept/Mx4rv7D_EBSHQdiLMuoH7dC2KQ" class="cyc_term">Ontology</a>), the latter of which includes a rich description of a domain, often including non-binary relations and complex rules. taxonomy Taxonomy The collection of all taxonomic systems.

A collection <code>COL</code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is itself an instance of <code>COL</code>, unless it is a temporal part of a temporal granule of <code>COL</code> (see <a href="http://sw.opencyc.org/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). More precisely, for a collection <code>COL</code> to be an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code>OBJ1</code> and <code>OBJ2</code> (with <code>OBJ2</code> at or above <code>COL</code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. Consider <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code>WALK</code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code>SUBWALK</code> of <code>WALK</code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code>SUBWALK</code> is itself an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. See <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> for the disjoint notion of being temporally object-like.

Each instance of <a href="http://sw.opencyc.org/concept/Mx4rwNgIyZwpEbGdrcN5Y29ycA" class="cyc_term">ClassificationSystem</a> is an agreed-upon or conventional classification system consisting of several <a href="http://sw.opencyc.org/concept/Mx4rvubaMZwpEbGdrcN5Y29ycA" class="cyc_term">ConventionalClassificationType</a>s (q.v.). In such a system, a change or reclassification is possible by a decision of an authority, or by a changed social agreement, without changing the intrinsic natures of the actual objects in the classificatory categories. <a href="http://sw.opencyc.org/concept/Mx4rwNgIyZwpEbGdrcN5Y29ycA" class="cyc_term">ClassificationSystem</a>s include biological taxonomies, standard classifications, data dictionaries, thesauri, cultural taboo systems, military doctrinal systems, and calendar systems. conventional classification system ClassificationSystem wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name
