Ask HN: Information extraction software?

5 pointsmjfern4 comments

I'm looking for information extraction software that I can feed in historical legal agreements and it will report:

1. Changes in the text between the documents

2. Changes in other attributes of the documents (e.g., word count)

3. % change over time in the text and attributes (e.g., text in the 1986 version of the doc is 56% different than the text in the 1985 version of the doc)

Can anyone please point me to software that might fit this particular need?

Thanks in advance! Michael
