Research
My research focuses mainly within the field of Natual
Language Learning. More specifically, my PhD will look at
developing techniques for efficient and accurate grammar
induction systems. My supervisor is Eric
Atwell.
Previous work looked at employing clustering techniques
for unsupervised learning of parts-of-speech. I was
fortunate enough to have collaborated with John Elliott
- who is a well established researcher in unsupervised
language learning.
I've recently become very interested in Arabic computional linguistics. I've developed a couple of
tools, including aConCorde, an Arabic concordancer, and a program for converting between Buckwalter transliteration
system and Unicode. I'm interested in standard CL tools like stemmers, taggers and parsers too.

In my spare time I have been known to submit some articles for technology sites about Linux and Java, amongst other things.
