Field Documentation

LexicalAssocMem* Lexicon::associative_memory

The associative memory that stores the lexicon entry graphies

IntArray* Lexicon::frequency

The dynamic array that stores the lexicon entry frequencies

LongArray* Lexicon::lemma

The dynamic array that stores the lexicon entry lemmas

Morpho Lexicon::max_pos

The largest part of speech numeric value used

Remarks:

This value is useful to avoid conflicts with grammar non-terminals

PointerArray* Lexicon::open_pos

The dynamic array of OpenPosTableItem that stores the list of open parts of speech and its associated probabilities

Remarks:

A lexicon is usually not exhaustive. For a better out-of-vocabulary forms handling, a lexicon allows to store occurency probabilities of the parts of speech for the unrecognized words

IntArray* Lexicon::part_of_speech

The dynamic array that stores the numerical representation or lexicon entry parts of speech

BidirectionalTrie* Lexicon::pos_map

The map table between the internal (numeric) and external (string) representation of parts of speech

Remarks:

This feature is only available for CHARACTER type lexicon

lexiconCreate()

DoubleArray* Lexicon::probability

The dynamic array that stores the lexicon entry probabilities
