gov.nih.nlm.nls.lvg.Flows.ToUninflectWords

public class ToUninflectWords
extends Transformation

This class gets uninflected variants of all words of a specified term and returns every combination of uninflected words. The uninflected variants are generated by Lvg facts or rules. A heuristic rule is applied when more than ten output combinations is generated by the rules. In such case, the original term is used to replace all output combinations.

Mutate

public static java.util.Vector<LexItem> Mutate(LexItem in,
                                               int maxTerm,
                                               java.sql.Connection conn,
                                               RamTrie trie,
                                               boolean detailsFlag,
                                               boolean mutateFlag)
                                        throws java.sql.SQLException

Performs the mutation of this flow component.

Parameters:

in - a LexItem as the input for this flow component

maxTerm - the max. no of result terms

conn - LVG database connection

trie - LVG Ram trie

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

Throws:

java.sql.SQLException - if errors occurr while connect to LVG database.

main

public static void main(java.lang.String[] args)

A unit test driver for this flow component.

Parameters:

args - arguments

FormCombinations

protected static java.util.Vector<java.lang.String> FormCombinations(java.util.Vector<java.util.Vector<java.lang.String>> inList)

Form the ouptut from a specified Vector. The input is a Vector of Vector of String - inList. In this flow (Uninflect Words), these elements are the uninflected terms for each word of the input term. This method is generic and can be used to form permutation in a multi-words term.

Parameters:

inList - is a Vector of Vector of String - uninflected term for each word in a term.

Returns:

A Vector of String - all permutation results from input.
