错误运行由斯坦福

Question

给出的公开信息提取

我试图运行NLP使用在官方网站上给出的指令由斯坦福大学给出的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) 
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

at java.lang.ClassLoader.loadClass(ClassLoader.java:357) 
... 2 more 

当我再次运行提供的Java代码：

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); 
    } 
} 
} 
} 

我得到了下一个错误：

任何帮助将不胜感激。

Answer 1

1. 第一个错误是，你没有SLF4J罐子，这是目前包括在GitHub上的最新版本：https://github.com/stanfordnlp/CoreNLP或者你可以在这里找到特定的jar：http://www.slf4j.org/download.html

2. 第二个错误是由“natlog”需要“解析”引起的。更改 “depparse” 到 “分析”：

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