These terms are not guaranteed to refer to the same concept across time but are guaranteed to be consistent within a particular OWL export. Use 'cycAnnot:externalID' for unambiguously referring to a concept across OWL exports or across Cyc inference engines. backreference NL attr type This <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkDZJwpEbGdrcN5Y29ycA" class="cyc_term">QuantityType</a> includes all NL attributes which are 'backreferential' in nature, e.g., used to refer to objects which have appeared previously in the discourse. Compare these to <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rSILiwljTEdeGdQACs2TnIQ" class="cyc_term">Demonstrative_NLAttrType</a>, which is used primarily when referring to particular tangible and/or temporal objects.

For example, Japanse 'kono'. this Backreference-ClassC-NLAttr Backreference Class C NL Attr <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rSIMw4FjTEdeGdQACs2TnIQ" class="cyc_term">Backreference_ClassC_NLAttr</a> covers items which are used when referring back to an object which is pragmatically distant from the backreferencing item, but is (in some language-specific way) considered 'close' or 'relevant' to the 'listener'. For example, Japanse would use 'sore' (ClassC) when referring to commonplace collections such as peasants, but 'are' (ClassB) when referring to a faraway individual such as Mt. Fuji. Backreference-ClassB-NLAttr <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rSIMJ1FjTEdeGdQACs2TnIQ" class="cyc_term">Backreference_ClassB_NLAttr</a> covers items which are used when referring back to an object which is pragmatically distant from the backreferencing item, typically within an earlier sentence. For example, Japanese 'are' or English 'that'. that natural language definiteness attribute NLDefinitenessAttribute Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvoKutZwpEbGdrcN5Y29ycA" class="cyc_term">NLDefinitenessAttribute</a> are attribute values that specify the definitness of an utterance.

Backreference-NLAttrType A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwIE23ZwpEbGdrcN5Y29ycA" class="cyc_term">TimeDependentCollection</a> (q.v.). This is the collection of all and only those collections <code>COL</code> such that any thing's being an instance of <code>COL</code> depends on the current state of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjqoZwpEbGdrcN5Y29ycA" class="cyc_term">CycKB</a>. Such a <code>COL</code> corresponds to a property defined (at least partly) in terms of the contents, features, or implementation of the Cyc Knowledge Base itself, as opposed to a property that "exists out there" in the KB-independent world. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvV281JwpEbGdrcN5Y29ycA" class="cyc_term">CycLAssertion</a> is a KB-dependent collection, membership in which requires of a given CycL sentence that it has in fact been asserted to the KB. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAoJwpEbGdrcN5Y29ycA" class="cyc_term">CycLSentence</a> is also KB-dependent, as being a CycL sentence requires being composed (ultimately) out of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvu6KTZwpEbGdrcN5Y29ycA" class="cyc_term">CycLReifiedDenotationalTerm</a>s (and perhaps variables) -- i.e. terms that are currently reified in the KB. Conversely, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv5ddsJwpEbGdrcN5Y29ycA" class="cyc_term">Sentence</a> is not a KB-dependent collection.
