我想要的代碼片斷這將需要輸入一個句子或一組句子和輸出或提取使用Java中的斯坦福CoreNLP包的三元組(主語,謂語和賓語)如何在java中使用Stanford CoreNLP包提取三元組?

您是否在尋找OpenIE三倍,或更有條理關係三元組(例如,對於像per:city_of_birth
)?對於前者,OpenIE系統可能是您要查找的內容:https://stanfordnlp.github.io/CoreNLP/openie.html。從那裏複製例子:
import edu.stanford.nlp.ie.util.RelationTriple;
import edu.stanford.nlp.simple.*;
/**
* A demo illustrating how to call the OpenIE system programmatically.
*/
public class OpenIEDemo {
public static void main(String[] args) throws Exception {
// Create a CoreNLP document
Document doc = new Document("Obama was born in Hawaii. He is our president.");
// Iterate over the sentences in the document
for (Sentence sent : doc.sentences()) {
// Iterate over the triples in the sentence
for (RelationTriple triple : sent.openieTriples()) {
// Print the triple
System.out.println(triple.confidence + "\t" +
triple.subjectLemmaGloss() + "\t" +
triple.relationLemmaGloss() + "\t" +
triple.objectLemmaGloss());
}
}
}
}
或者,使用註釋器API:
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.naturalli.NaturalLogicAnnotations;
import edu.stanford.nlp.util.CoreMap;
import java.util.Collection;
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,lemma,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());
}
}
}
}
