NAME

6       AI::Categorizer::Category - A named category of documents
7

SYNOPSIS

9         my $category = AI::Categorizer::Category->by_name("sports");
10         my $name = $category->name;
11
12         my @docs = $category->documents;
13         my $num_docs = $category->documents;
14         my $features = $category->features;

16         $category->add_document($doc);
17         if ($category->contains_document($doc)) { ...
18

DESCRIPTION

20       This simple class represents a named category which may contain zero or
21       more documents.  Each category is a "singleton" by name, so two
22       Category objects with the same name should not be created at once.
23

METHODS

25       new()
26           Creates a new Category object and returns it.  Accepts the

35
36       by_name(name => $string)
37           Returns the Category object with the given name, or creates one if
38           no such object exists.
39
40       documents()
41           Returns a list of the Document objects in this category in a list

43
