This produces a more aesthetically pleasing output:

VBD for/IN a/DT long/JJ time/NN marked/VBN by/IN no/DT

We can use the following code sequence to produce the same results. The
word
and
tag
methods extract the words and their tags:
List<TaggedWord> taggedSentence =
tagger.tagSentence(sentence);
for (TaggedWord taggedWord : taggedSentence) {
System.out.print(taggedWord.word() + "/" +
taggedWord.tag() + " ");
}
System.out.println();
If we are only interested in finding specific occurrences of a given tag, we can use a se-
quence such as the following, which will list only the singular nouns (
NN
):
List<TaggedWord> taggedSentence =
tagger.tagSentence(sentence);
for (TaggedWord taggedWord : taggedSentence) {
if (taggedWord.tag().startsWith("NN")) {
System.out.print(taggedWord.word() + " ");
