Проект Penn Treebank. Посмотрите на Отметка части речи.

JJ является прилагательным. NNS - существительное, множественное число. VBP - это настоящее время глагола. RB - наречие.

Что для английского. Для китайца это Penn Chinese Treebank. И для немца это корпус NEGRA.

Что касается вашего второго вопроса о поиске определенного POS (например, Noun) помеченного слова/фрагмента, вот пример кода, который вы можете следовать.

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);
}

Вывод:

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

Теги Stanford CoreNLP для других языков: французский, испанский, немецкий...

Я вижу, вы используете парсер для английского языка, который является моделью по умолчанию. Вы можете использовать синтаксический анализатор для других языков (французский, испанский, немецкий...) и, имейте в виду, что как токенизаторы, так и часть речевых тегов различны для каждого языка. Если вы хотите сделать это, вы должны загрузить определенную модель для языка (используя, например, конструктор, такой как Maven), а затем установить модель, которую вы хотите использовать. Здесь у вас есть больше информации об этом.

Вот вам списки тегов для разных языков:

1. Теги POS для Stanford CoreNLP для испанского языка
2. Тег POS для Stanford CoreNLP для немецкого языка использует набор тегов Штутгарт-Тюбинген (STTS)
3. POS-тег Stanford CoreNLP для французского языка использует следующие теги:
