Java 在斯坦福核心NLP中使用管道

我在Eclipse中设置了一个Maven项目

它们的唯一类是src/main/java/App.java 包com.nlptools.corenlp

import java.util.List;

import edu.stanford.nlp.pipeline.Annotation;
import edu.stanford.nlp.sentiment.SentimentPipeline;
import edu.stanford.nlp.pipeline.StanfordCoreNLP;

class App 
{
    public static void main( String[] args )
    {
        List<Annotation> list = SentimentPipeline.getAnnotations(new StanfordCoreNLP(), null, "foo.txt", false);
        for (Annotation item : list) {
            System.out.println(item.toString());
        }
        System.out.println( "Hello World!" );
    }
}

我正在查看文档，但无法理解：

我遗漏了什么？

在Maven依赖项中，您需要这一点：

<dependency>
    <groupId>edu.stanford.nlp</groupId>
    <artifactId>stanford-corenlp</artifactId>
    <version>3.9.2</version>
    <classifier>models</classifier>
</dependency>

管道变量是什么类型的？我如何初始化它？哎呀，我将把它添加进去。

Couldn't read TokensRegexNER from edu/stanford/nlp/models/kbp/english/gazetteers/regexner_caseless.tab

<dependency>
    <groupId>edu.stanford.nlp</groupId>
    <artifactId>stanford-corenlp</artifactId>
    <version>3.9.2</version>
    <classifier>models</classifier>
</dependency>

Properties props = new Properties();
props.setProperty("annotators", "tokenize,ssplit,pos,lemma,ner,parse,sentiment");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
CoreDocument exampleDocument = new CoreDocument("I loved the movie!");
pipeline.annotate(exampleDocument);
System.out.println(exampleDocument.sentences().get(0).sentiment());
