Типичным рабочим процессом является использование annotate() с подходящими конвейерами аннотаторов для получения аннотаций, а затем использование AnnotatedPlainTextDocument() для их объединения с аннотируемым текстом. Это дает объект, наследуемый от «AnnotatedPlainTextDocument» и «TextDocument», из которого можно получить текст и аннотации, используя соответственно as.character() и annotation(). Существуют методы для класса AnnotatedPlainTextDocument и общие слова(), sents(), paras(), tagged_words(), tagged_sents(), tagged_paras(), chunked_sents(), parsed_sents() и parsed_paras(), предоставляющие структурированные представления текст в таких документах. Все это требует, чтобы необходимые аннотации были доступны в используемом объекте аннотации. Методы универсальных шаблонов tagged_words(), tagged_sents() и tagged_paras() предоставляют механизм для сопоставления тегов POS с помощью аргумента карты, см. раздел «Подробности» на странице справки для tagged_words() для получения дополнительной информации. Используемый набор тегов POS будет выводиться из элемента метаданных POS_tagset используемого объекта аннотации.
