Abstract:
Gene function curation via Gene Ontology (GO) annotation is a common task among Model Organism Database (MOD) groups. Due to its manual nature, this task is time-consuming and labor-intensive, and thus considered one of the bottlenecks in literature curation. There have been many previous attempts at automatic identification of GO terms and supporting information from full-text. However, few systems have delivered an accuracy that is comparable to human annotators. One recognized challenge in developing such systems is the lack of marked passage-level evidence text that provides the basis for making GO annotations. To this end, we aim to create a corpus that includes the GO evidence text along with the three essential elements of GO annotations: 1) a gene or gene product, 2) a GO term and 3) a GO evidence code. To ensure our results are consistent with real-life GO annotation data, we recruited a team of eight professional GO curators from the biocuration community, and asked them to follow their routine GO annotation protocols. With the aid of a web-based annotation tool, our annotators marked up nearly 4,000 unique text passages in 200 full-text articles where on average each unique GO term is annotated with four different evidence text passages. Our corpus analysis shows that most of the evidence text occurs in the body of the article while comparatively as little as 12% appears in the abstracts. This result demonstrates the necessity of using full text for text mining GO terms. Through its use as the official data set for the BioCreative IV GO (BC4GO) task, we expect our unique BC4GO corpus to become a valuable resource for the BioNLP research community.
