CALBC (Collaborative Annotation of a Large Biomedical Corpus) is a European Support Action addressing the automatic generation of a very large, community-wide shared text corpus annotated with biomedical entities. We propose to create a broadly scoped and diversely annotated corpus (about one million Medline immunology-related abstracts annotated with different semantic types) by automatically integrating the annotations from different named entity recognition systems.
