java - 在斯坦福 Corenlp 中使用情感管道

Question

我已经在 Eclipse 中设置了一个 Maven 项目。

他们只是一个类，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!" );
    }
}

然后我添加这些依赖项并等待 Gradle 下载文件:

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

当我运行时出现此错误:

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

我正在查看文档，但无法理解它: https://nlp.stanford.edu/nlp/javadoc/javanlp/edu/stanford/nlp/sentiment/SentimentPipeline.html

我错过了什么？

您的 Maven 依赖项中需要这个:

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

此外，您可能只想在代码中使用标准管道:

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());
