This is the superclass for executable Text Categorization models. Upon compiling a subclass of this class, the required internal code will be generated to support the class' main methods <method>Categorize</method> and <method>CategorizeText</method>. To invoke a Text Categorization model on free text:
set tClassifier = ##class(User.MyClassifier).New()
write tClassifier.CategorizeText(.tCategories, "The helicopter was not flying at a sufficiently high altitude ...")
zwrite tCategories
To invoke it on a source in an iKnow domain:
set tClassifier = ##class(User.MyClassifier).New("iKnow", [domain name])
write tClassifier.Categorize(.tCategories, tSourceId)
zwrite tCategories

This method runs the Text Categorization model defined in <xdata>Classifier</xdata> against
the document identified by pSourceId. When this method returns, pCategories will contain all candidate categories for this document, sorted by decreasing score: pCategories(n) = $lb([category name], [score]) The entry with the highest score (pCategories(1)) is this model's best prediction.
If this Classifier instance has not been initialized with a reference to an iKnow or other domain, supply pMode="iKnow" and the domain name as pDomainSpec to point this classifier to the right location.

This method runs the Text Categorization model defined in <xdata>Classifier</xdata> against
the free text pText. When this method returns, pCategories will contain all candidate categories for this document, sorted by decreasing score: pCategories(n) = $lb([category name], [score]) The entry with the highest score (pCategories(1)) is this model's best prediction.
Optionally a <class>iKnow.Configuration</class>'s name can be passed in through pConfig to override the default configuration to use when indexing the text, for example to use a language model other than the default English (or automatically detect the right language to use).
