gov.nih.nlm.nls.lvg.Flows.ToLuiNormalize

All Implemented Interfaces:

java.lang.Cloneable

public class ToLuiNormalize
extends Transformation
implements java.lang.Cloneable

This class provides features of generating luiNorm for a specified term. This flow component is consist of 10 other flow components in a serial order. They are: q7, g, rs, o, t, l, B, C, w, q8.

If the flow component B generates multiple outputs in LuiNorm, the results are determined as shown in the following two cases:

• Fact:
  All citation forms are in the database and thus the results will be all the same (after canonicalized). The program will use the first output as the input for next flow component, Canonicalize.
• Uninflected by rules:
  In most cases, the uninflected forms will not in the Lvg database. Thus, different results will be generated by canonicalization depending on which uninflected term the program pick. In this release, the results from uninflected terms (by rules) is sorted by an alphabetical order. Thus, theis program pick up the first one from the uninflected terms for canonicalization since it is unique and consistent.

Accordingly, the output should only contain one LexItem.
