Java St​​anford NLP:品詞ラベル?

here でデモされたスタンフォードNLPは、次のような出力を提供します。

Colorless/JJ green/JJ ideas/NNS sleep/VBP furiously/RB ./.

品詞タグはどういう意味ですか?公式リストが見つかりません。それはスタンフォード独自のシステムですか、それともユニバーサルタグを使用していますか? (たとえば、JJとは何ですか?)

また、たとえば名詞を探して文を繰り返し処理しているとき、タグ.contains('N')かどうかを確認するようなことをすることになります。これはかなり弱い感じです。音声の特定の部分をプログラムで検索するより良い方法はありますか?

ペンツリーバンクプロジェクト品詞タグ付け psを見てください。

JJは形容詞です。 NNSは名詞、複数形です。 VBPは動詞現在形です。 RBは副詞です。

それは英語です。中国人にとっては、ペンチャイニーズツリーバンクです。そしてドイツ人にとっては、NEGRAコーパスです。

特定のPOS(例:名詞)タグ付きのワード/チャンクを見つけるという2番目の質問については、以下のサンプルコードをご覧ください。

public static void main(String[] args) {
    Properties properties = new Properties();
    properties.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse");
    StanfordCoreNLP pipeline = new StanfordCoreNLP(properties);

    String input = "Colorless green ideas sleep furiously.";
    Annotation annotation = pipeline.process(input);
    List<CoreMap> sentences = annotation.get(CoreAnnotations.SentencesAnnotation.class);
    List<String> output = new ArrayList<>();
    String regex = "([{pos:/NN|NNS|NNP/}])"; //Noun
    for (CoreMap sentence : sentences) {
        List<CoreLabel> tokens = sentence.get(CoreAnnotations.TokensAnnotation.class);
        TokenSequencePattern pattern = TokenSequencePattern.compile(regex);
        TokenSequenceMatcher matcher = pattern.getMatcher(tokens);
        while (matcher.find()) {
            output.add(matcher.group());
        }
    }
    System.out.println("Input: "+input);
    System.out.println("Output: "+output);
}

出力は次のとおりです。

Input: Colorless green ideas sleep furiously.
Output: [ideas]
