School of Information Studies - Faculty Scholarship

As part of our Evidence Extraction and Link Discovery (EELD) project, we proposed to use Transformation Based Learning (TBL) to learn domain-specific specializations for generic event extractions. The primary goal of our learning task was to reduce the amount of human effort required for specializing generic event extractions to domains that are new and specific. Three initial annotation cycles and one annotation review and correction cycle involving a total of 70 documents were completed, with slightly over 32 hours required for the entire annotation effort; where possible, the annotation cycles started with bootstrapped files resulting from the application of TBL …
