Cog

===

Cog is 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.

Features

--------

- IPA-based segmentation: automatically splits words in to segments

- Stem identification: identifies prefixes and suffixes so that they can be ignored during

comparison

- Word alignment: aligns segments between word pairs

- Sound correspondence identification: automatically identifies sound correspondences and the

environments in which they occur

- Likely cognate identification: provides various methods for identifying likely cognates

- Lexical/phonetic similarity: calculates lexical/phonetic similarity for multiple language

varieties

- Visualization: generates similarity matrices, hierarchical graphs (UPGMA, Neighbor-joining), and

network graphs

Experimentation

---------------

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.
