使用Nutch我已经抓取了URL，抓取了数据并将输出转储为文本。现在我有文本数据，我想从中提取/删除地址信息。我怎样才能做到这一点 ？
如果我没有错，那么在这种情况下只有注册 - 我不会帮助我，我应该编写一个reg-ex，然后是一些代码逻辑。
任何人都可以帮我解决这个问题吗？
提前致谢。

代码：
private static Pattern regexPreciseData = Pattern.compile("(?:(no|NO|No|(?:(p|P)?\\.?\\s?(o|O)?\\.?\\s?((B|b)(o|O)(x|X))))?(?:\\s?\\.?\\#?\\/?\\:?\\-?\\s?)[0-9]\\/?\\:?)+(?:\\,?\\s?\\w+\\s?){2,5}(?:\\s?\\w+\\s?)\\-?\\s?(\\d{2,5})",Pattern.CASE_INSENSITIVE);
utils.getText(sb, root); // extract text
text = sb.toString();
sb.setLength(0);
Matcher addressPattern = regexPreciseData.matcher(text);
while (addressPattern.find()) {
int start = addressPattern.start();
int end = addressPattern.end();
sb.append(text.substring(start, end));
}
text = sb.toString();
从上面的代码中你可以看到我正在尝试将我的文本与正则表达式模式匹配，并仅从中删除地址信息。但我的正则表达式也匹配一些不相关的数据。许多人认为只有reg-ex才能准确到足以从文本中删除地址信息。
答案 0 :(得分：1)
使用信息提取库或框架检测地址。对此有很多工作，这总是比在文本上编写正则表达式更好。
例如，您可以利用ANNIE附带的helper，这是一个可以提取地址的简单IE管道。一种方法是使用GATE并在其中运行GATE或导出为GATE格式，以便您可以单独运行GATE。您还可以在GATE模块中为Behemoth搭载代码并为Nutch编写自定义解析器，以便在Nutch中完成提取。
还有其他NLP资源可以做到这一点，检查UIMA等...再次，它是自然语言处理领域的一项着名的运动，你不需要重新发明轮子。
您还应该查看Behemoth并为Nutch编写自定义ParseFilter来处理直接从Nutch注释微数据的页面。
希望这会有所帮助。
