Program for comparing Chinese texts

[Morten Schlütter]

H all,

Does anyone have suggestions for a program that will run a comparison of two Chinese texts? I am looking for matching character strings, the text themselves are quite different.

Thanks,

Morten

Hi Morten,

Give QuotationFinder a try – 

<http://www.asia-europe.uni-heidelberg.de/en/research/heidelberg-research-architecture/projects/hra4-quotationfinder/download.html>.

Go for one of the zip downloads.

I think the Unix "diff" command would work fine. I use it within Emacs but it is also a standalone program. Since the Mac OS X is based on Darwin (a Unix variant) it is built-in and you can get it from the terminal.

A diff shows differences, but Morten wants matches. Plagiarism checkers find matches, even fuzzy ones. Perhaps what Morten is thinking of is the algorithm which finds parallel passages in ctext.org <http://ctext.org/tools/parallel-passages>.

A lot of Mac apps can do diffs – for instance, TextWrangler <http://www.barebones.com/products/textwrangler/>.

Well yes, but non-differences are matches!!

Yes, but "the texts themselves are quite different," as Morten writes, and diff checks line by line and then character by character. What if the lines are all jumbled? Applications like QuotationFinder goes beyond a simple diff, using different techniques to find matches anywhere in the text.

Note that you can submit texts to the project, here:

Not sure what Sturgeon's attitude is toward whatever you might want to add, but the requirements don't mention any restrictions about the types of texts:

Might make sense to contact him and ask for advice:

This isn't what you are looking for, but I think it is worth mentioning here. AntConc is a Mac OS X-friendly concordance generator, which has recently added a basic segmentation tool for Japanese and Chinese texts:

The segmentation tool is here:

I wouldn't bet the house on it working well with Chinese religious texts, but you never know. I think this stuff is geared toward linguistics and translation research. The developer is based in Japan at Waseda University -- he is currently active and seems open to suggestions.
