A tool for comparing languages using lexicostatistics and comparative linguistics techniques. It can be used to automate much of the process of comparing word lists from different language varieties.
The goal of Cog is to provide a framework for experimenting with different techniques for language variety comparison. It is intended to be used iteratively: run a comparison, analyze the results, refine the process, run the comparison again, and so on. Most steps in the process can be tailored. It currently only supports a few comparison techniques, but we hope to include many more in the future.
Cog allows you to quickly produce results by automating many of the steps of the word list comparison process:
Cog allows you to visualize your results from many different perspectives. Cog will automatically generate the following types of visual representations:
