stanford-nlp - 运行斯坦福给出的开放信息提取时出错

Question

我正在尝试使用官方网站中给出的命令运行stanford nlp给出的openIE:http://nlp.stanford.edu/software/openie.shtml

java -mx1g -cp stanford-openie.jar:stanford-openie-models.jar edu.stanford.nlp.naturalli.OpenIE  mytextfile.txt

但我收到以下错误:

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
at edu.stanford.nlp.pipeline.StanfordCoreNLP.<clinit>(StanfordCoreNLP.java:99)
at edu.stanford.nlp.naturalli.OpenIE.main(OpenIE.java:679)

... 2 more

再次运行给定的java代码时:

package edu.stanford.nlp.naturalli;

import edu.stanford.nlp.ie.util.RelationTriple;
import edu.stanford.nlp.ling.CoreAnnotations;
import edu.stanford.nlp.pipeline.Annotation;
import edu.stanford.nlp.pipeline.StanfordCoreNLP;
import edu.stanford.nlp.util.CoreMap;

import java.util.Collection;
import java.util.List;
import java.util.Properties;

public class OpenIEDemo {

public static void main(String[] args) throws Exception {
// Create the Stanford CoreNLP pipeline
Properties props = new Properties();
props.setProperty("annotators", "tokenize,ssplit,pos,depparse,natlog,openie");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

// Annotate an example document.
Annotation doc = new Annotation("Obama was born in Hawaii. He is our president.");
pipeline.annotate(doc);

// Loop over sentences in the document
for (CoreMap sentence : doc.get(CoreAnnotations.SentencesAnnotation.class)) {

  // Get the OpenIE triples for the sentence
  Collection<RelationTriple> triples = sentence.get(NaturalLogicAnnotations.RelationTriplesAnnotation.class);

  // Print the triples
  for (RelationTriple triple : triples) {
    System.out.println(triple.confidence + "\t" +
        triple.subjectLemmaGloss() + "\t" +
        triple.relationLemmaGloss() + "\t" +
        triple.objectLemmaGloss());
  }

  // Alternately, to only run e.g., the clause splitter:
  List<SentenceFragment> clauses = new OpenIE(props).clausesInSentence(sentence);
  for (SentenceFragment clause : clauses) {
    System.out.println(clause.parseTree);
  }
}
}
}

我收到下一个错误:

任何帮助将不胜感激。

第一个错误是您没有 slf4j jar，它目前包含在 GitHub 上的最新版本中:https://github.com/stanfordnlp/CoreNLP或者你可以在这里找到那个特定的 jar :http://www.slf4j.org/download.html

第二个错误是由“natlog”需要“解析”引起的。将“depparse”改为“parse”:

props.setProperty("annotators", "tokenize,ssplit,pos,parse,natlog,openie");
