Research Interests

Most of my work is in the field of Natural Language Processing although it is also been influenced by related areas such as Information Retrieval and Machine Learning.

Areas I have worked on recently include:

  • Lexical Semantics (analysis of word meaning), including word sense disambiguation, lexical similarity and hybrid distributional/knowledge-based models.
  • Information Extraction (identification of structured knowledge from text), particularly distant supervision approaches to relation extraction.
  • Biomedical and Medical Text Processing (supporting access to medical literature), including word sense disambiguation, relation extraction, literature-based discovery/data mining and contradiction identification.
  • Document analysis including identification of text reuse/plagiarism and author identification.
