Metric: seqeval
Hosted in S3


seqeval is a Python framework for sequence labeling evaluation. seqeval can evaluate the performance of chunking tasks such as named-entity recognition, part-of-speech tagging, semantic role labeling and so on. This is well-tested by using the Perl script conlleval, which can be used for measuring the performance of a system that has processed the CoNLL-2000 shared task data. seqeval supports following formats: IOB1 IOB2 IOE1 IOE2 IOBES See the [] file at for more information.

How to load this metric directly with the datasets library:
