Integration with Coh-Metrix

[slavakurilyak]

As a developer, I want to integrate with Coh-Metrix, so that I can evaluate cohesion, coherence and readability of texts.

Hi @slavakurilyak 👋 !

Thanks for requesting this, and adding a link to the paper. I'll have a read and see what we can do!

I've read the paper and it seems that Coh-Metrix is software. The source code doesn't seem to be available.

From what I can tell, this is the paper about version 1.0, but the software is currently 3.0.

Coh-Metrix: Analysis of text on cohesion and language
AC Graesser, DS McNamara, MM Louwerse (2004)

There is an online tool available at http://tool.cohmetrix.com/.

The paper that was originally linked uses results from Coh-Metric to determine the readability. With the formula it proposes being:

-45.032 + 52.230 * Content word overlap
        + 61.306 * Sentence syntax similarity
        + 22.205 * CELEX frequency

However, textstat doesn't currently calculate any of the above features of a text.
