我正在使用斯坦福自然语言处理工具包。我一直试图用Lexicon
的{{1}}方法找到拼写错误,但它会产生很多误报。所以我以为我会加载第二个词典,并检查一下。但是,这会导致问题。
isKnown
生成以下失败跟踪:
private static LexicalizedParser lp = new LexicalizedParser(Constants.stdLexFile);
private static LexicalizedParser wsjLexParse = new LexicalizedParser(Constants.wsjLexFile);
static {
lp.setOptionFlags(Constants.lexOptionFlags);
wsjLexParse.setOptionFlags(Constants.lexOptionFlags);
}
public ParseTree(String input) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException {
initialInput = input;
DocumentPreprocessor process = new DocumentPreprocessor();
sentences = process.getSentencesFromText(new StringReader(input));
for (List<? extends HasWord> sent : sentences) {
if(lp.parse(sent)) { // line 65
forest.add(lp.getBestParse()); //non determinism?
}
}
partsOfSpeech = pos();
runAnalysis();
}
如果我注释掉这一行:(以及对wsjLexParse的其他引用)
java.lang.ArrayIndexOutOfBoundsException: 45547

然后一切正常。我在这里做错了什么?
答案 0 :(得分:0)
看起来像斯坦福图书馆的一个错误。你应该向他们报告。
第二个词典只在你加载(而不是另一个词典)时是否有效? 以不同顺序加载两个lexica时是否会出现相同的错误?
