All Implemented Interfaces:

java.lang.Cloneable

public class ToDerivationByCategory
extends Transformation
implements java.lang.Cloneable

This class provides features of generating derivational variants for specified categories. This class utilize classes of ToDerivation and OutputFilter.

Derivational variants are terms which are somehow related to the original term but do not share the same meaning. Often, the derivational variant changes syntactic category from the original term. Derivational variants are pre-computed and are put in Derivation table in Lvg database (facts). Derivations can also be generated by derivation rules through Lvg trie.

Method Detail

Mutate

public static java.util.Vector Mutate(LexItem in,
                                      java.sql.Connection conn,
                                      RamTrie trie,
                                      int restrictFlag,
                                      long outCategory,
                                      boolean detailsFlag,
                                      boolean mutateFlag)

Performs the mutation of this flow component.

Parameters:

in - a LexItem as the input for this flow component

conn - LVG database connection

trie - LVG Ram trie

restrictFlag - a numberical flag to restrict out into LVG_ONLY LVG_OR_ALL, or ALL (defined in OutputFilter).

outCategory - the specified categories for output filter

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

Returns:

the results from this flow component - a collection (Vector) of LexItems
