xml - 使用不可见的 XML 从文本中提取记录

Question

我有 bibliography of periodicals 的 OCR 文本包含结构化条目。我想使用 Invisible XML提取和解析条目的标准。

示例输入:

每个条目都以条目号开头，后跟一个或多个空白字符，然后是用换行符分隔的描述性文本。

iXML 语法

data: entry+ .
entry: -#a, entrynum, " "+, content .
entrynum: -digit+ .
digit: ["1"-"9"] .
content: ~[]+; -#a+ .

这种对 iXML 语法的初始尝试产生了不明确的解析(使用 CoffeePot iXML processor )。

输出

首先，我想了解如何对条目进行分块，然后开始解析内容:例如，每个条目编号后跟一个或多个空格，然后是字母数字标题，后跟句点，等

Answer 1

“也许吧。” iXML 的一大优势是它可以处理歧义。这使得语法更容易编写。如果模棱两可的选择同样有效，或者如果您不关心选择了哪个模棱两可的选择，那么它就非常有效。

对于书目数据，我怀疑某些选择比其他选择更有效，而且您确实关心选择了哪个选择，这使得它更难。我还敢打赌，由于 OCR 不完善，因此存在很多的歧义。

我认为单个 iXML 语法不会解析输入并准确生成您想要的输出，但它可能构成更广泛策略的有用部分。我首先尝试将引用书目划分为单独的条目，将语法限制为仅一个条目。然后我可能会看看我是否可以计算出不同类别的条目(书籍、杂志、期刊等)，并且可能为每个类别使用不同的语法。

祝你好运!
