How to use Stanford parser
提问by SahelSoft
I downloaded the Stanford parser 2.0.5 and use Demo2.java source code that is in the package, but After I compile and run the program it has many errors. A part of my program is:
我下载了Stanford parser 2.0.5 并使用了包中的Demo2.java 源代码，但是在我编译并运行程序后，它有很多错误。我的程序的一部分是：
public class testStanfordParser {
/** Usage: ParserDemo2 [[grammar] textFile] */
public static void main(String[] args) throws IOException {
String grammar = args.length > 0 ? args[0] : "edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz";
String[] options = { "-maxLength", "80", "-retainTmpSubcategories" };
LexicalizedParser lp = LexicalizedParser.loadModel(grammar, options);
TreebankLanguagePack tlp = new PennTreebankLanguagePack();
GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
...
the errors are:
错误是：

I am using Stanford parser to extract entities like name ,location,organization.
我正在使用斯坦福解析器来提取名称、位置、组织等实体。
Here is my code:
这是我的代码：
public class stanfrdIntro {
public static void main(String[] args) throws IOException, SAXException,
{
String serializedClassifier = "classifiers/english.all.3class.distsim.crf.ser.gz";
AbstractSequenceClassifier<CoreLabel> classifier = CRFClassifier
.getClassifierNoExceptions(serializedClassifier);
String s1 = "Good afternoon Rahul Kulhari, how are you today?";
s1 = s1.replaceAll("\s+", " ");
String t=classifier.classifyWithInlineXML(s1);
System.out.println(Arrays.toString(getTagValues(t).toArray()));
}
private static final Pattern TAG_REGEX = Pattern.compile("<PERSON>(.+?)</PERSON>");
private static Set<String> getTagValues(final String str) {
final Set<String> tagValues = new HashSet<String>();
//final Set<String> tagValues = new TreeSet();
final Matcher matcher = TAG_REGEX.matcher(str);
while (matcher.find()) {
tagValues.add(matcher.group(1));
}
return tagValues;
}
This might help you but i am extracting only entities.
这可能对你有帮助，但我只提取实体。

All grammars are located in the included models jar. Is the "stanford-parser-2.0.5-models.jar" in the execution directory or classpath?
所有语法都位于包含的模型 jar 中。执行目录或类路径中的“stanford-parser-2.0.5-models.jar”是什么？
