我在使用stanford nlp时遇到了问题。我在尝试使用斯坦福核心NLP工具时遇到各种错误的问题。我想知道通过的句子的情绪。但是当我从eclipse运行代码时,我已经无法使用nlp工具了,并且需要将类似的jar添加到类路径中,
这是我想要执行的代码。

System.out.println(sentiment);

}
}
}

System.out.println("Average");
}

{
System.out.println("Positive");
}
else if(mainSentiment<2)
{
System.out.println("Negative ");
}
if (mainSentiment == 2 || mainSentiment > 4 || mainSentiment < 0) {
//return null;
}
}
public static void main(String[] args)
{
sentiment_analysis("Cristiano Ronaldo, is a Portuguese professional footballer who plays for Spanish club Real Madrid and the Portugal national team. He is a forward and serves as captain for Portugal.Often ranked as the best player in the world and rated by some in the sport as the greatest of all time");
}
}
我正在使用日食火星。起初它显示错误的ejml库。但后来我导入了ejml jar文件,以便错误得到解决,但它现在引起了这个错误......

我坚持认为。如果有人对此有任何想法,那么请建议,这将有很大的帮助。我已经在stackoverflow上搜索了其他类似的问题,但仍然没有得到解决方案来解决这个问题。
答案 0 :(得分:2)
实际上问题是使用了不同的版本。一些jar文件,比如xom,ejml缺少。我通过从版本为3.6.0的stanford核心NLP站点下载完整的jar文件来修复它。其中一个导入语句已更改为
import edu.stanford.nlp.neural.rnn.RNNCoreAnnotations;
SentimentCoreAnnotations.AnnotatedTree.class需要更改为 SentimentCoreAnnotations.SentimentAnnotatedTree.class
此更改已解决了我的所有错误。

您似乎在新模型旁边使用旧版CoreNLP(3.3.0)。尝试下载3.6.0代码+模型。
