      A natural-language representation for a concept that is both human 
      readable and readable by the Cyc inference engine. These terms are not 
      guaranteed to refer to the same concept across time but are guaranteed to

For example,  &lt;code&gt;&lt;b&gt;TERM2&lt;/b&gt;&lt;/code&gt; is, in the relevant sense, broader than &lt;code&gt;&lt;b&gt;TERM1&lt;/b&gt;&lt;/code&gt; if any of the following hold:&lt;br&gt;&lt;br&gt;

 &lt;code&gt;&lt;b&gt;TERM2&lt;/b&gt;&lt;/code&gt; is a collection that subsumes &lt;code&gt;&lt;b&gt;TERM1&lt;/b&gt;&lt;/code&gt;; &lt;br&gt;

 &lt;code&gt;&lt;b&gt;TERM2&lt;/b&gt;&lt;/code&gt; is a collection, instances of which have instances of the collection &lt;code&gt;&lt;b&gt;TERM1&lt;/b&gt;&lt;/code&gt; as parts; &lt;br&gt;
