Field Documentation

NTItemDerivationList* NTItemList::current_derivation

Derivation currently treated by the extraction process (required for the iterative analysis extraction)

Todo:

documentation to validate

NTItemDerivationList* NTItemList::derivation_list

List of all the interpretations that produce the same syntactic rule left part

Todo:

documentation to validate

Counter NTItemList::interpretation_counter

Total number of interpretations associated to the item (and its sub-items)

gboolean NTItemList::is_on_top

Set to TRUE if there is no non-terminal above this in tree using a trivial rule. For example, if there is a rule:

• A -> B: B.nt_item_list.is_on_top is set to FALSE;
• A -> B C: B.nt_item_list.is_on_top is set to TRUE.

Remarks:

Probability NTItemList::maximum_probability

Maximum (or Viterbi) probability of the item

NTItemList* NTItemList::next

The next item of the list (NULL if there is no item left)

Probability NTItemList::sum_probability

Total (or inside) probability of the item

Counter NTItemList::ties_counter

A number of ties with the most probable parse
