我有一个资源,我确切地知道单词的类型。我必须对它们进行引理,但为了获得正确的结果,我必须手动标记它们。我找不到任何手动标记单词的代码。我使用以下代码,但它返回错误的结果。即#34;绘画"为'"绘画"我期待的地方" paint"。
*//...........lemmatization starts........................
Properties props = new Properties();
props.put("annotators", "tokenize, ssplit, pos, lemma");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props, false);
String text = "painting";
Annotation document = pipeline.process(text);
List<edu.stanford.nlp.util.CoreMap> sentences = document.get(SentencesAnnotation.class);
for(edu.stanford.nlp.util.CoreMap sentence: sentences)
{
for(CoreLabel token: sentence.get(TokensAnnotation.class))
{
String word = token.get(TextAnnotation.class);
String lemma = token.get(LemmaAnnotation.class);
System.out.println("lemmatized version :" + lemma);
}
}
//...........lemmatization ends.........................*
我必须在单词上运行lemmatizer而不是自动完成pos标记的句子。所以我先手动标记这些单词,然后找到它们的引理。帮助一些示例代码或对某个站点的引用会有很大的帮助。

如果您事先知道POS标签,可以通过以下方式获取结构标记:
Properties props = new Properties();
props.put("annotators", "tokenize, ssplit");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props, false);
String text = "painting";
Morphology morphology = new Morphology();
Annotation document = pipeline.process(text);
List<edu.stanford.nlp.util.CoreMap> sentences = document.get(SentencesAnnotation.class);
for(edu.stanford.nlp.util.CoreMap sentence: sentences) {
for(CoreLabel token: sentence.get(TokensAnnotation.class)) {
String word = token.get(TextAnnotation.class);
String tag = ... //get the tag for the current word from somewhere, e.g. an array
String lemma = morphology.lemma(word, tag);
System.out.println("lemmatized version :" + lemma);
}
}
如果您只想获得单个单词的引理,您甚至不必运行CoreNLP进行标记化和句子分割,因此您可以将引理函数调用如下:
String tag = "VBG";
String word = "painting";
Morphology morphology = new Morphology();
String lemma = morphology.lemma(word, tag);
