斯坦福nlp中的NER模型训练

Question

我一直在尝试与斯坦福核心NLP合作。我希望训练我自己的NER模型。从论坛上的SO和官网上描述了如何使用一个属性文件来实现这一点。我将如何通过API实现它？。

Properties props = new Properties();
props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, sentiment, regexner");
props.setProperty("regexner.mapping", "resources/customRegexNER.txt");

StanfordCoreNLP pipeline = new StanfordCoreNLP(props);      

String processedQuestion = "Who is the prime minister of Australia?"

//Annotation annotation = pipeline.process(processedQuestion);
Annotation document = new Annotation(processedQuestion);
pipeline.annotate(document);
List<CoreMap> sentences = document.get(SentencesAnnotation.class);
for (CoreMap sentence : sentences) {

    // To get the tokens for the parsed sentence
    for (CoreMap tokens : sentence.get(TokensAnnotation.class)) {           
        String token = tokens.get(TextAnnotation.class);
        String POS = tokens.get(PartOfSpeechAnnotation.class);      
        String NER = tokens.get(NamedEntityTagAnnotation.class);            
        String Sentiment = tokens.get(SentimentClass.class);            
        String lemma = tokens.get(LemmaAnnotation.class);

1. 怎么做

Answer 1

我认为它可以与该代码一起工作：

val props = new Properties()
  props.put("annotators", "tokenize, ssplit, pos, lemma, ner, regexner")
  props.put("ner.model", "/your/path/ner-model.ser.gz");
  val pipeline = new StanfordCoreNLP(props)
