从不同的非结构化文本文件中检索信息 - 文本挖掘?
我需要一些帮助来解决这个问题。
我们有大量给定指定域的文档。这些文档来自不同的来源,因此它们的结构也可能非常不同。另一方面,我有一个包含一些指定字段的表格,其中必须从文档的摘录中填充一些数字。
例如:
x 公司的业务量为 2010 年 20mio。1,000,000 美元是交换 今年是y公司。
结果应该是这样的,
|| Company | Year | Volume
|| X | 2010 | 200,000
|| Y | 2010 | 1000,000
您能给我指出一些链接或主题吗,我可以在其中找到如何解决此类问题的更多信息。
我知道对此没有现成的解决方案,但我应该从哪里开始寻找。
提前致谢。
I need some help in solving this problem.
We have a large amount of documents of a given specified domain. These documents are from differente sources and therefore their structure can be very different too. On the other side I have a table with some specified fields where some figures has to be filled from the extract of the documents.
For example:
Company x had a business volume of
$20mio in 2010. $1,000,000 was the exchange of
company y this year.
The result should something like this
|| Company | Year | Volume
|| X | 2010 | 200,000
|| Y | 2010 | 1000,000
Can you point me please to some links or topics, where I can find further informations how to solve such a problem.
I know that there is no out of the box solution for this, but where should i start to look for.
Thanks in advance.

好的。有整个计算机科学实验室专门研究这类东西!
也许可以从寻找一个名为 RapidMiner 的工具开始
另外,这里还有一些我的研究论文标题PDF(遗憾的是我不再有链接):

我认为第一个对您所追求的东西最感兴趣。不太确定它会有多少价值:)
Ok. There are entire computer science labs devoted to that sort of stuff!
Maybe start by looking a tool called RapidMiner
Also here are a couple of research paper titles I have as PDF's (which I don't have links for anymore sadly):

I think the first one would be of greatest interest in terms of what you are after. Not quite sure how much value it will be though :)
