Question

我是NLP的新手，我一直试图从原始文本中提取与年龄相关的信息。我用谷歌搜索，并没有得到任何语言的任何可靠的库来满足这个要求。如果我能在这方面得到任何帮助，那将是很棒的。我对任何语言都持开放态度并不是一种约束。它也可以是Java，Python或任何其他语言。任何帮助将非常感激。提前致谢。干杯！

我尝试将斯坦福帮助提到的注释器添加到我的java解析器中，我面临以下异常：

我升级到1.6.0版本，并将stanford-corenlp-models-current.jar添加到类路径中。如果我遗失了某些内容，请告诉我

更新1：

升级到3.9.1后修复了异常。但我得到的输出是：持续时间关系而不是每个年龄

private static AnnotationPipeline makePipeline() {

    Properties props = new Properties();
    props.setProperty("annotators",
             "tokenize,ssplit,pos,lemma,ner,depparse,coref,kbp");
    StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
    return pipeline;


}

public static void parse(String str) {
    try {
        Annotation doc = new Annotation(str);
        pipeline.annotate(doc);
        ArrayList<CoreMap> resultRelations = new ArrayList<CoreMap>();
        List<CoreMap> mentionsAnnotations = doc.get(MentionsAnnotation.class);
        for (CoreMap currentCoreMap : mentionsAnnotations) {
            System.out.println(currentCoreMap.get(TextAnnotation.class));
            System.out.println(currentCoreMap.get(CharacterOffsetBeginAnnotation.class));
            System.out.println(currentCoreMap.get(CharacterOffsetEndAnnotation.class));
            System.out.println(currentCoreMap.get(NamedEntityTagAnnotation.class));
        }
    } catch (Exception e) {

    }
}

这是正常行为还是我做错了什么？

您可能会发现KBP关系提取器很有用。

示例文字：

Joe Smith is 58 years old.

命令：

java -Xmx12g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,depparse,coref,kbp -file example.txt -outputFormat text

这应该Joe Smith附加58 years old与per:age关系。

使用nlp提取与年龄相关的信息
