Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVj755wpEbGdrcN5Y29ycA" class="cyc_term">Scientist</a> is a person who is educated and employed in one (or more) of the natural, social, or abstract sciences. Specializations of <a href="http://sw.opencyc.org/concept/Mx4rvVj755wpEbGdrcN5Y29ycA" class="cyc_term">Scientist</a> include the collections <a href="http://sw.opencyc.org/concept/Mx4rvVj_A5wpEbGdrcN5Y29ycA" class="cyc_term">Astronomer</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVjKrpwpEbGdrcN5Y29ycA" class="cyc_term">Chemist</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVirtpwpEbGdrcN5Y29ycA" class="cyc_term">Linguist</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVkB15wpEbGdrcN5Y29ycA" class="cyc_term">Mathematician</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVj_RZwpEbGdrcN5Y29ycA" class="cyc_term">Geneticist</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvVkBlZwpEbGdrcN5Y29ycA" class="cyc_term">CulturalAnthropologist</a>. 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 Scientist engaged in the development and application of Physics physicist Physicist 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 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. This predicate is roughly equivalent to rdfs:seeAlso. See Also URI scientist type by field A collection of collections. Each instance is a spec of <a href="http://sw.opencyc.org/concept/Mx4rvVj755wpEbGdrcN5Y29ycA" class="cyc_term">Scientist</a> whose instances are all of the same field. ScientistTypeByField PersonWithOccupation The collection of persons who have a (skilled or unskilled) occupation. Most (but not all) instances of <a href="http://sw.opencyc.org/concept/Mx4rvVjnN5wpEbGdrcN5Y29ycA" class="cyc_term">PersonWithOccupation</a> spend a significant part of their waking hours doing activities that are characteristic of their occupations. Typically their actions are performed for pay (but not always: consider a "starving artist" who is unable to sell any of her works). Note that a <a href="http://sw.opencyc.org/concept/Mx4rvVjnN5wpEbGdrcN5Y29ycA" class="cyc_term">PersonWithOccupation</a> need not be working over the entire duration of when s/he has an occupation; e.g. college professors on summer break and the temporarily unemployed still have occupations. Most reified specializations of <a href="http://sw.opencyc.org/concept/Mx4rvVjnN5wpEbGdrcN5Y29ycA" class="cyc_term">PersonWithOccupation</a> classify workers according to their job titles, the kinds of work they perform, or the skills involved; while a few exploit other (usually quite broad) features of their working lives (e.g. <a href="http://sw.opencyc.org/concept/Mx4rvVkALJwpEbGdrcN5Y29ycA" class="cyc_term">SelfEmployedWorker</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVirGJwpEbGdrcN5Y29ycA" class="cyc_term">DeskWorker</a>). But note that many collections corresponding to what are colloquially considered professions or occupations (e.g. <a href="http://sw.opencyc.org/concept/Mx4rvVkBGJwpEbGdrcN5Y29ycA" class="cyc_term">Lifeguard</a>, #$StockBroker, <a href="http://sw.opencyc.org/concept/Mx4rvViUT5wpEbGdrcN5Y29ycA" class="cyc_term">Housekeeper</a>, and many others) are _not_ specializations of <a href="http://sw.opencyc.org/concept/Mx4rvVjnN5wpEbGdrcN5Y29ycA" class="cyc_term">PersonWithOccupation</a>, as those collections include people for whom the work in question is not their occupation. worker 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 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>.
