MentalRetardation mental retardation A condition in which a person doesn't develop mentally and has much lower intelligence than average. MentalRetardation mental retardation 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> <b>THING</b> <b>URI</b>)</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 A condition in which a person doesn't develop mentally and has much lower intelligence than average. MentalRetardation mental retardation 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 &quot;implicitly quoted&quot; (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> <b>THING</b> <b>EXPR-TYPE</b>)</code> does <i>not</i> mean that <code><b>THING</b></code> itself is an instance of <code><b>EXPR-TYPE</b></code>. Rather, such a sentence is partly self-referential, and means that the particular <i>CycL expression</i> appearing in the sentence's own first argument-position is an instance of <code><b>EXPR-TYPE</b></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). <p/> 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 <font color="#ff0000">#$PublicConstant</font>. We cannot express this with the straightforward <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> sentence <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a> <font color="#ff0000">#$PublicConstant</font>)</code>, as that states the falsehood that the IndianOcean itself -- which is <i>not</i> 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> <font color="#ff0000">#$PublicConstant</font>) . </pre> Now <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> is a <a href="http://sw.opencyc.org/concept/Mx4rv4oJWZwpEbGdrcN5Y29ycA" class="cyc_term">MacroRelation</a> (q.v.), and by its <a href="http://sw.opencyc.org/concept/Mx4rvVjg7JwpEbGdrcN5Y29ycA" class="cyc_term">expansion</a> any given <a href="http://sw.opencyc.org/concept/Mx4rBVVEokNxEdaAAACgydogAg" class="cyc_term">quotedIsa</a> sentence is equivalent to some <a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> sentence with an <i>explicitly</i> quoted first argument. The sentence displayed above turns out to be equivalent to: <pre> (<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> (<a href="http://sw.opencyc.org/concept/Mx4rgGBbEkNuEdaAAACgydogAg" class="cyc_term">Quote</a> <a href="http://sw.opencyc.org/concept/Mx4rvViH35wpEbGdrcN5Y29ycA" class="cyc_term">IndianOcean</a>) <font color="#ff0000">#$PublicConstant</font>). </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. <p/> 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 <i>open</i> expression, see the accompanying <font color="#ff0000">#$cyclistNotes</font>. Quoted Isa type of ailment A collection of collections. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rwQwW_pwpEbGdrcN5Y29ycA" class="cyc_term">PhysiologicalConditionType</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rwQw4WZwpEbGdrcN5Y29ycA" class="cyc_term">PhysiologicalCondition</a> (q.v.), and thus a type of physiological state into which some organisms can enter. Instances of <a href="http://sw.opencyc.org/concept/Mx4rwQwW_pwpEbGdrcN5Y29ycA" class="cyc_term">PhysiologicalConditionType</a> include <a href="http://sw.opencyc.org/concept/Mx4rwP1qGpwpEbGdrcN5Y29ycA" class="cyc_term">Cancer</a>, <a href="http://sw.opencyc.org/concept/Mx4rwP1baJwpEbGdrcN5Y29ycA" class="cyc_term">PsychologicalAilment</a>, <a href="http://sw.opencyc.org/concept/Mx4rwQwvf5wpEbGdrcN5Y29ycA" class="cyc_term">Infection</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvgC7mJwpEbGdrcN5Y29ycA" class="cyc_term">Malnutrition</a>. PhysiologicalConditionType chronic condition ChronicCondition A collection of ailments. An instance of <a href="http://sw.opencyc.org/concept/Mx4rwP1OVJwpEbGdrcN5Y29ycA" class="cyc_term">ChronicCondition</a> is an ailment that lingers or recurs in an organism throughout its life. In some cases, the symptoms of a chronic condition may abate with treatment. The condition may never go away completely. <a href="http://sw.opencyc.org/concept/Mx4rwP1iIJwpEbGdrcN5Y29ycA" class="cyc_term">Asthma</a> is an example of a subcollection of <a href="http://sw.opencyc.org/concept/Mx4rwP1OVJwpEbGdrcN5Y29ycA" class="cyc_term">ChronicCondition</a>. 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>.
