My research is in computational linguistics, focusing on robust statistical approaches to broad-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 information 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 formalisms 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 available is a prodigious task.
I am excited by the challenges of developing large-scale and robust deep-linguistic processing techniques that are feasible for tera-scale datasets. I believe that statistical parsing with lexicalised grammar formalisms, e.g. Combinatory 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-supervised knowledge acquisition. This will be crucial to overcoming the knowledge bottleneck that hampers real-world applications of NLP.
