Materials Science Named Entity Recognition: train/development/test sets

Training, development and test sets for supervised named entity recognition for materials science. The data is labelled using the IOB annotation scheme. There exist 7 entity tags: material (MAT), sample descriptor (DSC), symmetry/phase label (SPL), property (PRO), application (APL), synthesis method (SMT), and characterization method (CMT), along with the outside tag (O).The data consists of 800 hand-labelled materials science abstracts. The data has an 80-10-10 split, giving 640 abstracts in the training set, 80 in the development set, and 80 in the test set.
