Coh-Metrix calculates the coherence of texts on over 250 measures. It replaces common readability formulas by applying the latest in computational linguistics and linking this to the latest research in psycholinguistics.

A great too as it is! There are quite a lot of work to be done about the interpretation of the results of the data that generated. Could you tell me any books on the terms of the books to have a better understanding of the readability and coherence model that works behind the sheet of result? thanks a lot, franliang! The following is on of the results I got from the site. How can I generate sound interpretation of the results? Thanks a lot!

What is behind the Coh-Metrix is LATENT SEMANTIC ANALYSIS-LSA.

Here are some introductory papers about LSA.

Thank you all, I have got it. The registration is ok and the tool is great.

I did some work on Latent Semantic Analysis myself. It involves some matrix computations.
The results generated by Coh-Metrix are interpreted at the tool's website. Simply click the links to the left of the generated results, and another webpage will pop up. The interpretations are all given there.
