Pretty String (<a href="http://sw.opencyc.org/2008/06/10/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/2008/06/10/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 Rdfs:label rdfs:label <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rdpCjwNu9QdaChuanmVyrQg" class="cyc_term">rdfs_label</a>label is an imported RDFS/XML term equivalent to the Cyc term <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> control character free string ControlCharacterFreeString Pretty String (<a href="http://sw.opencyc.org/2008/06/10/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/2008/06/10/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 thing Thing <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a> is the "universal collection": the collection which, by definition, contains everything there is. Every thing in the Cyc ontology -- every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> (of any kind), every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>, and every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> -- is an instance of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Similarly, every collection is a subcollection of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBDpwpEbGdrcN5Y29ycA" class="cyc_term">genls</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Trivially, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a> is both an instance of and a subcollection of itself, and is not a subcollection of any other collection. (Note that the above reference to "every thing in the Cyc ontology" is not meant to be limited to things actually reified in the Cyc system, but includes (e.g.) every instance -- reified or not, known or not -- of every collection recognized by Cyc.) Pretty String (<a href="http://sw.opencyc.org/2008/06/10/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/2008/06/10/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 ProperNamePredicate-Loose loose proper name predicate Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvXygrJwpEbGdrcN5Y29ycA" class="cyc_term">ProperNamePredicate_Loose</a> are all the lexical predicates that can be used for the purpose of temporarily and rapidly registering the information that a certain STRING is (one of the) name(s) for a certain FORT. The salient feature of the predicates that are instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvXygrJwpEbGdrcN5Y29ycA" class="cyc_term">ProperNamePredicate_Loose</a> is that assertions made using those predicates are not guaranteed to contain all the grammatical information that would be necessary to handle morphological variants of the strings that appear in those assertions. For example, such assertions would not contain information on whether the STRING argument, can or cannot be pluralized when referring to the FORT argument. A prototypical example of such a predicate would be <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvgpArJwpEbGdrcN5Y29ycA" class="cyc_term">termStrings</a>. Compare to <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvs_C9JwpEbGdrcN5Y29ycA" class="cyc_term">ProperNamePredicate_Strict</a>. character sequence A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwQGTzJwpEbGdrcN5Y29ycA" class="cyc_term">AbstractInformationStructure</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> is a string of characters or an abstract sequence of symbols. Note that an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> is not any particular physical, tangible representation, since different encodings may represent the same string of characters. An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> is a list (see the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtUAU5wpEbGdrcN5Y29ycA" class="cyc_term">List</a>) of characters (instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVzt_ZwpEbGdrcN5Y29ycA" class="cyc_term">Character_Abstract</a>) from some fixed character set. An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> may be any finite length, including zero (the zero-length string is the empty string, which has no characters). Notable specializations of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjYb5wpEbGdrcN5Y29ycA" class="cyc_term">EMailAddress</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjCG5wpEbGdrcN5Y29ycA" class="cyc_term">AreaCode</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjs7pwpEbGdrcN5Y29ycA" class="cyc_term">PhoneNumber</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj3pZwpEbGdrcN5Y29ycA" class="cyc_term">TelephoneCountryCode</a>. Note that a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> is ordered formally as a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtUAU5wpEbGdrcN5Y29ycA" class="cyc_term">List</a> (rather than physically left-to-right or top-to-bottom); thus the 'first' character in the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a> for an Arabic word happens to be the rightmost (first pronounced) character, not the leftmost character, due to the letter-order and word-order convention for Arabic writing.
