windows stanford corenlp java类jar文件编译缺少“.”
我已经8年没有使用java了，但我不记得有人谈论过jar文件
我正在尝试像在链接NER example java code上那样执行NER过程。我复制了他们的示例java类NERPipelineDemo，位于链接处。当我试图编译NERPipelineDemo时，它出现了错误，看起来需要我从网站下载NER软件包。我在download stanford corenlp（红色下载按钮）下载了它，最后得到了一个非常大的jar文件。我将jar文件复制到NERPipelineDemo所在的目录中。java在中，并在顶部添加了一个导入。这是示例链接中程序的顶部，为我添加的导入行添加了注释
package edu.stanford.nlp.examples;
import stanford-english-corenlp-2018-10-05-models.*; //I added this line to example found online
import edu.stanford.nlp.pipeline.*;
import java.util.Properties;
import java.util.stream.Collectors;
public class NERPipelineDemo {
public static void main(String[] args) {
// set up pipeline properties
Properties props = new Properties();
props.setProperty("annotators", "tokenize,ssplit,pos,lemma,ner");
// example customizations (these are commented out but you can uncomment them to see the results
// disable fine grained ner
// props.setProperty("ner.applyFineGrained", "false");
// customize fine grained ner
// props.setProperty("ner.fine.regexner.mapping", "example.rules");
// props.setProperty("ner.fine.regexner.ignorecase", "true");
// add additional rules, customize TokensRegexNER annotator
// props.setProperty("ner.additional.regexner.mapping", "example.rules");
// props.setProperty("ner.additional.regexner.ignorecase", "true");
// add 2 additional rules files ; set the first one to be case-insensitive
// props.setProperty("ner.additional.regexner.mapping", "ignorecase=true,example_one.rules;example_two.rules");
// set document date to be a specific date (other options are explained in the document date section)
// props.setProperty("ner.docdate.useFixedDate", "2019-01-01");
// only run rules based NER
// props.setProperty("ner.rulesOnly", "true");
// only run statistical NER
// props.setProperty("ner.statisticalOnly", "true");
// set up pipeline
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
// make an example document
CoreDocument doc = new CoreDocument("Joe Smith is from Seattle.");
// annotate the document
pipeline.annotate(doc);
// view results
System.out.println("---");
System.out.println("entities found");
for (CoreEntityMention em : doc.entityMentions())
System.out.println("\tdetected entity: \t"+em.text()+"\t"+em.entityType());
System.out.println("---");
System.out.println("tokens and ner tags");
String tokensAndNERTags = doc.tokens().stream().map(token -> "("+token.word()+","+token.ner()+")").collect(
Collectors.joining(" "));
System.out.println(tokensAndNERTags);
}
}
我没有处理这个问题。下载jar文件之后，因为我在网上搜索了它，看起来我可以在java程序中引用它
因此，当我尝试编译程序时，我现在有4个错误，而不是6个：
NERPipelineDemo.java:3: error: '.' expected
import stanford-english-corenlp-2018-10-05-models.*;

NERPipelineDemo.java:3: error: ';' expected

我很难弄清楚丢失了什么是文件名为stanford-english-corenlp-2018-10-05-models。罐子
我从NER网站复制了示例代码，如图所示
有什么想法吗
更新：我确实找到了另一个question online for stanford corenlp，我尝试了他们所做的，并得到了错误
"Could not find or load main class NERPipelineDemo.java"
我也看到了steps to use official release，但他们并没有谈论我在下载链接/按钮上得到的jar文件。我想他们谈论的是github的zip下载
**更新2（项目构建/设置信息）： 在C:\Users\Michele\Documents中，我有：
stanford-english-corenlp-2018-10-05-models.jar (downloaded from link above, red button)
NERPipelineDemo.java (copied exactly from https://stanfordnlp.github.io/CoreNLP/ner.html and named as shown)
在我的文档目录命令提示符下，我尝试了javac NERPipelineDemo。java，但第一个错误列表是
C:\Users\Michele\Documents>javac NERPipelineDemo.java
NERPipelineDemo.java:4: error: package edu.stanford.nlp.pipeline does not exist

^
NERPipelineDemo.java:41: error: cannot find symbol

就在那时，我尝试添加 //进口stanford-english-corenlp-2018-10-05-models.*//添加到NERPipelineDemo。爪哇
然后它在这个问题的主题上出现了错误：
C:\Users\Michele\Documents>javac NERPipelineDemo.java
NERPipelineDemo.java:3: error: '.' expected
import stanford-english-corenlp-2018-10-05-models.*;

^
NERPipelineDemo.java:3: error: class, interface, or enum expected
import stanford-english-corenlp-2018-10-05-models.*;
^
4 errors
然后我想我没有正确使用jar，所以我尝试了在我的文档命令行的stackoverflow链接上推荐的方法
java -cp .;stanford-english-corenlp-2018-10-05-models.jar edu.stanford.nlp.pipeline
得到
Error: Could not find or load main class edu.stanford.nlp.pipeline
我肯定我不确定使用jar文件和/或使用java的过程是什么，因为我已经很生疏了，而且这里有很多新的api用法我还不习惯
我只是尝试向斯坦福图书馆提供一个字符串，以将nlp处理后的字符串作为可用输出（NERPipelineDemo、令牌和ner标记）
***更新3（响应后） 我删除了添加到NERPipelineDemo的导入。java，并使用和get错误编译，并更正了Update2中的命令：
javac -cp .;stanford-english-corenlp-2018-10-05-models.jar NERPipelineDemo.java
NERPipelineDemo.java:4: error: package edu.stanford.nlp.pipeline does not exist

我不知道该怎么办。我不习惯使用api。我需要为该jar文件添加多个cp吗？一个cp不应该涵盖一切吗
