So a ground atomic sentence of the form <code>(<a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> THING EXPR-TYPE)</code> does not mean that <code>THING</code> itself is an instance of <code>EXPR-TYPE</code>. Rather, such a sentence is partly self-referential, and means that the particular CycL expression appearing in the sentence's own first argument-position is an instance of <code>EXPR-TYPE</code>. Thus, <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> provides a convenient shorthand for stating certain things that would otherwise require explicit quotation (or some other device for naming expressions). This is better illustrated with a specific example. Suppose we wish to state that the CycL constant <code><a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a></code> is an instance of the CycL expression type #$PublicConstant. We cannot express this with the straightforward <a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> sentence <code>(<a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> <a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a> #$PublicConstant)</code>, as that states the falsehood that the IndianOcean itself -- which is not a constant but a body of water -- is a public constant. But we can express precisely what we want like this: <pre> (<a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> <a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a> #$PublicConstant) . </pre> Now <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> is a <a href="http://sw.opencyc.org/2009/04/07/concept/en/MacroRelation" class="cyc_term">MacroRelation</a> (q.v.), and by its <a href="http://sw.opencyc.org/2009/04/07/concept/en/expansion" class="cyc_term">expansion</a> any given <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> sentence is equivalent to some <a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> sentence with an explicitly quoted first argument. The sentence displayed above turns out to be equivalent to: <pre> (<a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> (<a href="http://sw.opencyc.org/2009/04/07/concept/en/Quote" class="cyc_term">Quote</a> <a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a>) #$PublicConstant). </pre> But the <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> version has two related practical advantages over the <a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> version. First, the former is syntactically simpler than the latter. Second, the simpler syntax of the former makes it easier to browse in the Knowedge Base: while the <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> version is conveniently indexed under the KB Browser page for the constant <code><a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a></code>, the <a href="http://sw.opencyc.org/2009/04/07/concept/en/isa" class="cyc_term">isa</a> version would apparently be indexed under a separate, brand new page for the term <code>(<a href="http://sw.opencyc.org/2009/04/07/concept/en/Quote" class="cyc_term">Quote</a> <a href="http://sw.opencyc.org/2009/04/07/concept/en/IndianOcean" class="cyc_term">IndianOcean</a>)</code>. Generalizing the point, <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a> lets us avoid having potentially to double the number of pages currently in the browser. For the semantically more complicated (but rarely encountered) case in which <a href="http://sw.opencyc.org/2009/04/07/concept/en/quotedIsa" class="cyc_term">quotedIsa</a>'s first argument-place is filled with an open expression, see the accompanying #$cyclistNotes. quotedIsa seeAlsoURI See Also URI <code>(<a href="http://sw.opencyc.org/2009/04/07/concept/en/seeAlsoURI" class="cyc_term">seeAlsoURI</a> THING URI)</code> means that a description of the resource identified by URI is likely to contain information pertinent to THING. This predicate is roughly equivalent to rdfs:seeAlso. prettyString Pretty String (<a href="http://sw.opencyc.org/2009/04/07/concept/en/prettyString" 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/2009/04/07/concept/en/prettyString" 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.

In each <a href="http://sw.opencyc.org/2009/04/07/concept/en/Clearing_RemovingSomething" class="cyc_term">Clearing_RemovingSomething</a>, someone removes something. Clearing-RemovingSomething clearing word net workflow constant not fully reviewed WordNetWorkflowConstant-NotFullyReviewed The collection of all <a href="http://sw.opencyc.org/2009/04/07/concept/en/CycLConstant" class="cyc_term">CycLConstant</a>s created from the import of concepts from <a href="http://sw.opencyc.org/2009/04/07/concept/en/WordNet_Version2_0" class="cyc_term">WordNet_Version2_0</a> that have not yet been fully reviewed by a <a href="http://sw.opencyc.org/2009/04/07/concept/en/HumanCyclist" class="cyc_term">HumanCyclist</a>.

Clearing-RemovingSomething clearing TypicalHumanActivityType-AtLeastOnce typical human activity type at least once The collection of specializations of <a href="http://sw.opencyc.org/2009/04/07/concept/en/HumanActivity" class="cyc_term">HumanActivity</a> such that persons typically are involved in (<a href="http://sw.opencyc.org/2009/04/07/concept/en/actors" class="cyc_term">actors</a>) at least one instance of the activity type in their lifetime. removing RemovingSomething A specialization of <a href="http://sw.opencyc.org/2009/04/07/concept/en/PurposefulAction" class="cyc_term">PurposefulAction</a>. Each instance of <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething" class="cyc_term">RemovingSomething</a> is an event in which an agent deliberately removes one object from another object. The removed object is related to the instance of <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething" class="cyc_term">RemovingSomething</a> via the predicate <a href="http://sw.opencyc.org/2009/04/07/concept/en/objectRemoved" class="cyc_term">objectRemoved</a>, while the object to which it belonged prior to its removal is related via the predicate <a href="http://sw.opencyc.org/2009/04/07/concept/en/objectRemaining" class="cyc_term">objectRemaining</a>. In different types of removals, either the <a href="http://sw.opencyc.org/2009/04/07/concept/en/objectRemoved" class="cyc_term">objectRemoved</a> or the <a href="http://sw.opencyc.org/2009/04/07/concept/en/objectRemaining" class="cyc_term">objectRemaining</a> may be destroyed, or both may survive. Specializations of <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething" class="cyc_term">RemovingSomething</a> include <a href="http://sw.opencyc.org/2009/04/07/concept/en/Ablation" class="cyc_term">Ablation</a>, <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething_Translational" class="cyc_term">RemovingSomething_Translational</a>, and <a href="http://sw.opencyc.org/2009/04/07/concept/en/CuttingOffAPiece" class="cyc_term">CuttingOffAPiece</a>. The difference between this collection and <a href="http://sw.opencyc.org/2009/04/07/concept/en/SeparationEvent" class="cyc_term">SeparationEvent</a> is that instances of <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething" class="cyc_term">RemovingSomething</a> are purposeful actions, while instances of <a href="http://sw.opencyc.org/2009/04/07/concept/en/SeparationEvent" class="cyc_term">SeparationEvent</a> need not be purposeful. A collection of events; a subcollection of <a href="http://sw.opencyc.org/2009/04/07/concept/en/RemovingSomething" class="cyc_term">RemovingSomething</a>. In each <a href="http://sw.opencyc.org/2009/04/07/concept/en/Clearing_RemovingSomething" class="cyc_term">Clearing_RemovingSomething</a>, someone removes something. Clearing-RemovingSomething clearing first-order collection An instance of <a href="http://sw.opencyc.org/2009/04/07/concept/en/CollectionType" class="cyc_term">CollectionType</a>, and a specialization of <a href="http://sw.opencyc.org/2009/04/07/concept/en/FixedOrderCollection" class="cyc_term">FixedOrderCollection</a>. <a href="http://sw.opencyc.org/2009/04/07/concept/en/FirstOrderCollection" class="cyc_term">FirstOrderCollection</a> is the collection of all specializations of <a href="http://sw.opencyc.org/2009/04/07/concept/en/Individual" class="cyc_term">Individual</a> (q.v.) Notable specializations of <a href="http://sw.opencyc.org/2009/04/07/concept/en/FirstOrderCollection" class="cyc_term">FirstOrderCollection</a> include <a href="http://sw.opencyc.org/2009/04/07/concept/en/TemporalObjectType" class="cyc_term">TemporalObjectType</a>, <a href="http://sw.opencyc.org/2009/04/07/concept/en/ExistingStuffType" class="cyc_term">ExistingStuffType</a>, and <a href="http://sw.opencyc.org/2009/04/07/concept/en/ExistingObjectType" class="cyc_term">ExistingObjectType</a>.
