Research interests

My research is in computational linguistics, focusing on robust statistical approaches to
coverage large
scale natural

language processing (NLP). My interests range from the
design of fundamental NLP components, including text processing and tagging tools,
through to statistical parsers and high
level systems for financial modelling using text,
question answering and info
rmation extraction.

My background is in computer science. Computational linguistics poses challenges that
require both algorithmic and implementation techniques of interest to computer scientists.
Meanwhile, computational linguists are developing complex f
ormalisms and statistical
models that enable increasingly detailed linguistic analyses. Unfortunately, greater fidelity
usually brings significant efficiency penalties. Providing even a superficial analysis of the
rapidly growing volume of text now availab
le is a prodigious task.

I am excited by the challenges of developing large
scale and robust deep
processing techniques that are feasible for tera
scale datasets. I believe that statistical
parsing with lexicalised grammar formalisms, e.g. Combi
natory Categorial Grammar (CCG),
and supertagging, provides the best trade
off between linguistic fidelity and efficiency.
Efficient, accurate parsing will enable us to create and exploit unprecedented quantities of
automatically analysed text using semi
upervised knowledge acquisition. This will be crucial
to overcoming the knowledge bottleneck that hampers real
world applications of NLP.
