&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;= The &amp;lt;nowiki&amp;gt;[[FaCT]]&amp;lt;/nowiki&amp;gt; System  =&lt;br /&gt;
&lt;br /&gt;
A result of IanHorrocks' research into optimising tableaux subsumption algorithms has been the development of the &amp;lt;nowiki&amp;gt;[[FaCT]]&amp;lt;/nowiki&amp;gt; system. '''&amp;lt;nowiki&amp;gt;[[FaCT]]&amp;lt;/nowiki&amp;gt;''' ('''Fa'''st '''C'''lassification of '''T'''erminologies) is a Description Logic (DL) classifier that can also be used for modal logic satisfiability testing. The [[FaCT]] system includes two reasoners, one for the logic [http://www.cs.man.ac.uk/%7Ehorrocks/Publications/download/1998/kr98.ps.gz SHF] (ALC augmented with transitive roles, functional roles and a role hierarchy) and the other for the logic [http://www.cs.man.ac.uk/%7Ehorrocks/Publications/download/1999/lpar99.ps.gz SHIQ] (SHF augmented with inverse roles and qualified number restrictions), both of which use sound and complete tableaux algorithms. &lt;br /&gt;
