From the webpage:
The goal of the Morpho project is to develop unsupervised data-driven methods that discover the regularities behind word forming in natural languages. In particular, we are focusing on the discovery of morphemes, which are the primitive units of syntax, the smallest individually meaningful elements in the utterances of a language. Morphemes are important in automatic generation and recognition of a language, especially in languages in which words may have many different inflected forms.
This may not be of general interest but I mention it as one aspect of data-driven linguistics.
Long dead languages are often victims of well-meaning but highly imaginative work meant to explain those languages.
Grounding work in texts of a language introduces a much needed sanity check.
