TagLattice
instance. A loop is used to obtain the
ConditionalClassifica-
tion
instance for each token in the lattice.
We are using the same
tokenList
instance developed in the previous section:
TagLattice<String> lattice = decoder.tagMarginal(tokenList);
for (int index = 0; index < tokenList.size(); index++) {
ConditionalClassification classification =
lattice.tokenClassification(index);
…
}
The
ConditionalClassification
class has a
score
and a
category
method.
The
score
method returns a relative score for a given category. The
category
method
returns this category, which is the tag. The token, its score, and category are displayed as
shown here:
System.out.printf("%-8s",tokenList.get(index));
for (int i = 0; i < 4; ++i) {
double score = classification.score(i);
String tag = classification.category(i);
System.out.printf("%7.3f/%-3s ",score,tag);
}
System.out.println();
The output is shown as follows:
