Little Richard LittleRichard RayCharles Ray Charles AntoineDomino-Songwriter An instance of <a href="http://sw.opencyc.org/concept/Mx4r7wQOfEeAEdaAAABQ2sS97g" class="cyc_term">Songwriter</a>. United States rhythm and blues pianist and singer and composer (born in 1928). Fats Domino AuthorTypeByFormat A collection of collections. Each instance is a spec of <a href="http://sw.opencyc.org/concept/Mx4rvViowZwpEbGdrcN5Y29ycA" class="cyc_term">Author</a> whose instances are all of the same format. author type by format 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 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 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 writer The kind of people that have written a composition, for example students, professional writers. Authors are NOT necessary professionals (see <a href="http://sw.opencyc.org/concept/Mx4rvVj7rpwpEbGdrcN5Y29ycA" class="cyc_term">Writer</a>) as they don't necessarily do it for pay, or do it as a central job related activity. Author Wikipedia Article URL (<a href="http://sw.opencyc.org/concept/Mx4rNv0nbm4TTjOp7yhmnzOyqg" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article located at URL wikipediaArticleURL WordNetWorkflowConstant-NotFullyReviewed word net workflow constant not fully reviewed The collection of all <a href="http://sw.opencyc.org/concept/Mx4rvzSRxJwpEbGdrcN5Y29ycA" class="cyc_term">CycLConstant</a>s created from the import of concepts from <a href="http://sw.opencyc.org/concept/Mx4rtfZxnO-3QdibF4NWtMhnaQ" class="cyc_term">WordNet_Version2_0</a> that have not yet been fully reviewed by a <a href="http://sw.opencyc.org/concept/Mx4rvViX3ZwpEbGdrcN5Y29ycA" class="cyc_term">HumanCyclist</a>. seeAlsoURI <code>(<a href="http://sw.opencyc.org/concept/Mx4riWVFR6HJSpaEaHrcWS3MSA" 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.
