Supporting the Curation of Biological Databases with Reusable Text Mining

Curators of biological databases transfer knowledge from scientiflc publications, a laborious and expensive manual process. Machine learning algorithms can reduce the workload of curators by flltering relevant biomedical literature, though their widespread adoption will depend on the availability of intuitive tools that can be conflgured for a variety of tasks. We propose a new method for supporting curators by means of document categorization, and describe the architecture of a curator-oriented tool implementing this method using techniques that require no computational linguistic or programming expertise. To demonstrate the feasibility of this approach, we prototyped an application of this method to support a real curation task: identifying PubMed abstracts that contain allergen cross-reactivity information. We tested the performance of two difierent classifler algorithms (CART and ANN), applied to both composite and single-word features, using several feature scoring functions. Both classiflers exceeded our performance targets, the ANN classifler yielding the best results. These results show that the method we propose can deliver the level of performance needed to assist database curation.
