    Pushing the boundaries of deep parsing
    I examine the application of deep parsing techniques to a range of Natural Language Processing tasks as well as methods to improve their performance. Focussing specifically on the English Resource Grammar, a hand-crafted grammar of English based on the Head-Driven Phrase Structure Grammar formalism, I examine some techniques for improving parsing accuracy in diverse domains and methods for evaluating these improvements. I also evaluate the utility of the in-depth linguistic analyses available from this grammar for some specific NLP applications such as biomedical information extraction, as well as investigating other applications of the semantic output available from this grammar.
