Question

我正在使用stanford CoreNLP页面here.

上描述的方法

为了从命令行运行Stanford CoreNLP，使用以下命令：

java -cp "*" -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt

我已从分发目录运行此命令。然而。我收到以下错误：

我的java版本是1.9，我下载的CoreNLP是最新版本，即。 3.7.0。

另外，我没有安装多个版本的Stanford CoreNLP。这个版本有问题吗？我哪里可能出错？

Answer 1

我从这里下载了分发文件夹：http://stanfordnlp.github.io/CoreNLP/download.html

我将它解压缩并插入stanford-corenlp-full-2016-10-31

我输入了这个命令：

import numpy as np
import pandas as pd
import seaborn as sns
sns.set(style="white")

# Generate a random correlated bivariate dataset
rs = np.random.RandomState(5)
mean = [0, 0]
cov = [(1, .5), (.5, 1)]
x1, x2 = rs.multivariate_normal(mean, cov, 500).T
x1 = pd.Series(x1, name="$X_1$")
x2 = pd.Series(x2, name="$X_2$")

# Show the joint distribution using kernel density estimation
g = sns.jointplot(x1, x2, kind="kde", size=7, space=0, xlim=(0.995, 1.005))

它运作正常。你有没有额外的罐子到文件夹？您在运行此类型的系统？

我正在运行Java 1.8，据我所知，Java 1.9还没有发布，所以这也可能是一个问题。

Answer 2

如果您使用 Java 9 ，您应该可以使用此命令：

java -cp "*" -Xmx2g --add-modules java.xml.bind edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt -outputFormat text

注意使用--add-modules java.xml.bind，此选项允许您解决错误NoClassDefFoundError：javax / xml / bind / JAXBException。

Answer 3

这已为我修复，将其添加到道具中：

import os

directory = os.fsencode("mydir")

for folder in os.listdir(directory):
    for file in os.listdir(folder):
        filename = os.fsdecode(file)
        if ((filename.endswith('.xlsx')) and (filename == 'Apples.xlsx')):
            filenames.append(filename)
filenames.sort()

MetaClass无法使用args [sutime，{}]创建公共edu.stanford.nlp.time.TimeExpressionExtractorImpl（java.lang.String，java.util.Properties）
