Class MorphologyProcessor

java.lang.Object

simplenlg.framework.NLGModule

simplenlg.morphology.english.MorphologyProcessor

public class MorphologyProcessor
extends NLGModule

This is the processor for handling morphology within the SimpleNLG. The processor inflects words form the base form depending on the features applied to the word. For example, kiss is inflected to kissed for past tense, dog is inflected to dogs for pluralisation.

As a matter of course, the processor will first use any user-defined inflection for the world. If no inflection is provided then the lexicon, if it exists, will be examined for the correct inflection. Failing this a set of very basic rules will be examined to inflect the word.

All processing modules perform realisation on a tree of NLGElements. The modules can alter the tree in whichever way they wish. For example, the syntax processor replaces phrase elements with list elements consisting of inflected words while the morphology processor replaces inflected words with string elements.

N.B. the use of module, processing module and processor is interchangeable. They all mean an instance of this class.

Method Detail

initialise

public void initialise()

Description copied from class: NLGModule

Performs one-time initialisation of the module.

Specified by:

initialise in class NLGModule

realise

public NLGElement realise(NLGElement element)

Description copied from class: NLGModule

Realises the given element. This call is usually recursive as the call processes the child elements of the given element.

Specified by:

realise in class NLGModule

Parameters:

element - the NLGElement to be realised.

Returns:

the NLGElement representing the realised state. This may be the initial element in a changed form or be a completely new element.

realise

public List<NLGElement> realise(List<NLGElement> elements)

Description copied from class: NLGModule

Realises a List of NLGElements usually by iteratively calling the realise(NLGElement) method on each element in the list and adding the result into a new a List

Specified by:

realise in class NLGModule

Parameters:

elements - the List of NLGElements to be realised.

Returns:

the List of realised NLGElements.
