Taraka Rama

PhD Student

---

 

I am enrolled in GSLT. My interests are in creation of language resources, unsupervised methods and computational historical linguistics. I am also a member with CLT

I worked on cognate identification and phylogeny in my Masters' thesis

I am a member of ASJP Consortium.

My first supervisor is Lars Borin.
My second supervisor is Søren Wichmann

I spent the spring of 2012 at Max Planck Institute for Evolutionary Anthropology, Leipzig.

I spent two months (March and April of 2013) as a Guest Researcher at Alpha-Informatica

There is an interesting open-source NLP toolkit for South Asian Languages Sanchay (means a Collection in Sanskrit).

A very honest PhD thesis
