      A natural-language representation for a concept that is both human

    <rdfs:comment xml:lang="en">A binary &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rDeDIGEW0EdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;MetaLanguagePredicate&lt;/a&gt; (q.v.) that relates CycL expressions to the &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4raOoTci9qEdma4AACs1uxFw&quot; class=&quot;cyc_term&quot;&gt;SubLExpressionType&lt;/a&gt;s (q.v.) of which they are instances.  &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; is thus like a restricted version of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; (q.v.), but with one important difference: the first argument-place of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; is &amp;quot;implicitly quoted&amp;quot; (see &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rwHb_bZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;quotedArgument&lt;/a&gt;).  So a ground atomic sentence of the form &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; &lt;b&gt;THING&lt;/b&gt; &lt;b&gt;EXPR-TYPE&lt;/b&gt;)&lt;/code&gt; does &lt;i&gt;not&lt;/i&gt; mean that &lt;code&gt;&lt;b&gt;THING&lt;/b&gt;&lt;/code&gt; itself is an instance of &lt;code&gt;&lt;b&gt;EXPR-TYPE&lt;/b&gt;&lt;/code&gt;.  Rather, such a sentence is partly self-referential, and means that the particular &lt;i&gt;CycL expression&lt;/i&gt; appearing in the sentence&apos;s own first argument-position is an instance of &lt;code&gt;&lt;b&gt;EXPR-TYPE&lt;/b&gt;&lt;/code&gt;.  Thus, &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; provides a convenient shorthand for stating certain things that would otherwise require explicit quotation (or some other device for naming expressions).
&lt;p/&gt;
This is better illustrated with a specific example.  Suppose we wish to state that the CycL constant &lt;code&gt;&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt;&lt;/code&gt; is an instance of the CycL expression type &lt;font color=&quot;#ff0000&quot;&gt;#$PublicConstant&lt;/font&gt;.  We cannot express this with the straightforward &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; sentence &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt; &lt;font color=&quot;#ff0000&quot;&gt;#$PublicConstant&lt;/font&gt;)&lt;/code&gt;, as that states the falsehood that the IndianOcean itself -- which is &lt;i&gt;not&lt;/i&gt; a constant but a body of water -- is a public constant.  But we can express precisely what we want like this:
&lt;pre&gt;
  (&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt; &lt;font color=&quot;#ff0000&quot;&gt;#$PublicConstant&lt;/font&gt;) .
&lt;/pre&gt;  
Now &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; is a &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rv4oJWZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;MacroRelation&lt;/a&gt; (q.v.), and by its &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVjg7JwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;expansion&lt;/a&gt; any given &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; sentence is equivalent to some &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; sentence with an &lt;i&gt;explicitly&lt;/i&gt; quoted first argument.  The sentence displayed above turns out to be equivalent to: 
&lt;pre&gt;
  (&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; (&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rgGBbEkNuEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;Quote&lt;/a&gt; &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt;) &lt;font color=&quot;#ff0000&quot;&gt;#$PublicConstant&lt;/font&gt;).
&lt;/pre&gt; 
But the &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; version has two related practical advantages over the &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; 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 &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; version is conveniently indexed under the KB Browser page for the constant &lt;code&gt;&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt;&lt;/code&gt;, the &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; version would apparently be indexed under a separate, brand new page for the term &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rgGBbEkNuEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;Quote&lt;/a&gt; &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;IndianOcean&lt;/a&gt;)&lt;/code&gt;. Generalizing the point, &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt; lets us avoid having potentially to double the number of pages currently in the browser.
&lt;p/&gt;
For the semantically more complicated (but rarely encountered) case in which &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg&quot; class=&quot;cyc_term&quot;&gt;quotedIsa&lt;/a&gt;&apos;s first argument-place is filled with an &lt;i&gt;open&lt;/i&gt; expression, see the accompanying &lt;font color=&quot;#ff0000&quot;&gt;#$cyclistNotes&lt;/font&gt;.</rdfs:comment>
