Class Attribute Details

.dictionaries ⇒ Object

An array of dictionary files. Each element should be of the form: [file, whether_dic_include_frequency_info]. This should be set before the dictionaries are loaded (They are loaded only when they are used). Or else you should call Dictionary.instance.reload manually to reload the dictionaries.

def dictionaries
  @dictionaries
end

.max_word_length ⇒ Object

The maximum length of a CJK word. The default value is 4. Making this value too large might slow down the segment operations.

# File 'lib/rmmseg/config.rb', line 16

def algorithm
  @algorithm
end

.algorithm=(algor) ⇒ Object

Set the algorithm name used to segment. Valid values are :complex and :simple . The former is the default one.

def algorithm=(algor)
  unless [:complex, :simple].include? algor
    raise ArgumentError, "Unknown algorithm #{algor}"
  end
  @algorithm = algor
end

.algorithm_instance(text, tok = Token) ⇒ Object

Get an instance of the algorithm object corresponding to the algorithm name configured. tok is the class of the token oject to be returned. For example, if you want to use with Ferret, you should provide ::Ferret::Analysis::Token .

# File 'lib/rmmseg/config.rb', line 31

def algorithm_instance(text, tok=Token)
  RMMSeg.const_get("#{@algorithm}".capitalize+"Algorithm").new(text, tok)
end

.on_ambiguity ⇒ Object

Get the behavior description when an unresolved ambiguity occured.

def on_ambiguity
  @on_ambiguity
end

.on_ambiguity=(behavior) ⇒ Object

Set the behavior on an unresolved ambiguity. Valid values are :raise_exception and :select_first . The latter is the default one.
