If you have a question about this talk, please contact Timothy G. Griffin. When publishing a scientific paper, authors pay great attention to how they talk about previous work: They cite it (in a easy-to-detect way), compare their own work to it (which is harder to detect), and make evaluative statements about its quality (which is the hardest to detect). All of these pieces of information can be invaluable when building information access systems such as summarisers or citation indexers. But without NLP , only citations are readily detectable (and Google Scholar and similar citation indexers do). My work looks at how to use discourse context and NLP to tease more information out of the text: sentiment towards citations, explicit statements of self-praise and comparison to others. Automatic annotation is based on supervised machine learning from lower-level sentential features. The data used comes from two different domains (computational linguistics and chemistry). Results are in the form of human annotation agreement, similarity of automatic and human annotations, and measures of usefulness for search.
