SemRep Gold Standard Annotation
In early 2011, we conducted a gold standard annotation study in which we annotated 500 sentences randomly selected from MEDLINE abstracts with semantic predications. The results are mainly intended to serve as an evaluation testbed for SemRep. They can also be used by other information extraction systems based on UMLS domain knowledge. The study consisted of three phases: a) practice phase b) main annotation phase and c) adjudication phase.
Here, we present two sets of annotations from the main phase as well as the adjudicated gold standard. For further details, refer to our BMC Bioinformatics paper "Constructing A Semantic Predication Gold Standard from the Biomedical Literature" or contact Halil Kilicoglu.
