Question

我想知道如何使用StanfordCoreNLP在段落中找到句子的开头和结尾位置。现在我正在使用DocumentPreprocessor将段落拆分成句子。是否有可能获得句子实际位于原始文本中的起点和终点索引？

我正在使用此处提出的另一个问题的代码。

String paragraph = "My 1st sentence. “Does it work for questions?” My third sentence.";
Reader reader = new StringReader(paragraph);
DocumentPreprocessor dp = new DocumentPreprocessor(reader);
List<String> sentenceList = new ArrayList<String>();

for (List<HasWord> sentence : dp) {
   String sentenceString = Sentence.listToString(sentence);
   sentenceList.add(sentenceString.toString());
}

for (String sentence : sentenceList) {
   System.out.println(sentence);
}

取自：How can I split a text into sentences using the Stanford parser?

Answer 1

快速而肮脏的方法是：

import edu.stanford.nlp.simple.*;

Document doc = new Document("My 1st sentence. “Does it work for questions?” My third sentence.");
for (Sentence sentence : doc.sentences()) {
  System.out.println(sentence.characterOffsetBegin(0) + " -- " + sentence.characterOffsetEnd(sentence.length() - 1));
}

否则，您可以从CoreLabel中提取CharacterOffsetBeginAnnotation和CharacterOffsetEndAnnotation，并使用它在原始文本中查找令牌的偏移量。
