It is the computer program of which <a href="http://sw.opencyc.org/concept/Mx4rvViAZZwpEbGdrcN5Y29ycA" class="cyc_term">Cyc</a> (and, indeed, every instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjqXZwpEbGdrcN5Y29ycA" class="cyc_term">CycTheCollection</a>) is a copy (see <a href="http://sw.opencyc.org/concept/Mx4rwSiusZwpEbGdrcN5Y29ycA" class="cyc_term">programCopies</a>). the Cyc program cyc agent CycAgent quotedIsa A binary <a href="http://sw.opencyc.org/concept/Mx4rDeDIGEW0EdaAAACgydogAg" class="cyc_term">MetaLanguagePredicate</a> (q.v.) that relates CycL expressions to the <a href="http://sw.opencyc.org/concept/Mx4raOoTci9qEdma4AACs1uxFw" class="cyc_term">SubLExpressionType</a>s (q.v.) of which they are instances. <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> is thus like a restricted version of <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> (q.v.), but with one important difference: the first argument-place of <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> is "implicitly quoted" (see <a href="http://sw.opencyc.org/concept/Mx4rwHb_bZwpEbGdrcN5Y29ycA" class="cyc_term">quotedArgument</a>). So a ground atomic sentence of the form <code>(<a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" 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/concept/Mx4rBVVEokNxEdaAAACgydogAg" 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/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a></code> is an instance of the CycL expression type #$PublicConstant. We cannot express this with the straightforward <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> sentence <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a> #$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/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a> #$PublicConstant) . </pre> Now <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> is a <a href="http://sw.opencyc.org/concept/Mx4rv4oJWZwpEbGdrcN5Y29ycA" class="cyc_term">MacroRelation</a> (q.v.), and by its <a href="http://sw.opencyc.org/concept/Mx4rvVjg7JwpEbGdrcN5Y29ycA" class="cyc_term">expansion</a> any given <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> sentence is equivalent to some <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> sentence with an explicitly quoted first argument. The sentence displayed above turns out to be equivalent to: <pre> (<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> (<a href="http://sw.opencyc.org/concept/Mx4rgGBbEkNuEdaAAACgydogAg" class="cyc_term">Quote</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a>) #$PublicConstant). </pre> But the <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> version has two related practical advantages over the <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" 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/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> version is conveniently indexed under the KB Browser page for the constant <code><a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a></code>, the <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" 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/concept/Mx4rgGBbEkNuEdaAAACgydogAg" class="cyc_term">Quote</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a>)</code>. Generalizing the point, <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" 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/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a>'s first argument-place is filled with an open expression, see the accompanying #$cyclistNotes. Quoted Isa BT broaderTerm <code>(<a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> means that <code>TERM2</code> is broader than <code>TERM1</code>, in an extremely general sense of "broader". For example, <code>TERM2</code> is, in the relevant sense, broader than <code>TERM1</code> if any of the following hold: <code>TERM2</code> is a collection that subsumes <code>TERM1</code>; <code>TERM2</code> is a collection that has <code>TERM1</code> as an instance; <code>TERM2</code> is a collection, instances of which have instances of the collection <code>TERM1</code> as parts; <code>TERM2</code> has <code>TERM1</code> as a part; This list of reasons for why <code>(<a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> could hold is not exhaustive, but it should give a good indication of how general the <a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> relation actually is. Cyc Cyc <a href="http://sw.opencyc.org/concept/Mx4rvViAZZwpEbGdrcN5Y29ycA" class="cyc_term">Cyc</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjqXZwpEbGdrcN5Y29ycA" class="cyc_term">CycTheCollection</a>, #$SoftwareAgent, and <a href="http://sw.opencyc.org/concept/Mx4rv0AAKJwpEbGdrcN5Y29ycA" class="cyc_term">IndexicalConcept</a>.

E.g., 'Suppose a cat walks into a fish store. The cat is likely to get into a lot of trouble.' 'The cat' in the second sentence refers back to 'a cat' in the first; i.e., any cat that walks into a fish store. In Cyc, the constraints for a <a href="http://sw.opencyc.org/concept/Mx4rvViAz5wpEbGdrcN5Y29ycA" class="cyc_term">TheTerm</a> in a given context are given by use of the predicate <a href="http://sw.opencyc.org/concept/Mx4rwP3W_ZwpEbGdrcN5Y29ycA" class="cyc_term">theTermConstraints</a> on the unit representing that context. In lifting assertions out of that context, the constraints are added as antecedents. the term TheTerm
