Natural Language Annotation for Machine Learning

Appendix A. List of Available Corpora and Specifications

This appendix was compiled primarily from the LRE Resource Map. Many thanks to Nicoletta Calzolari and Riccardo del Gratta for their help in creating this appendix, and for allowing us to reprint this information here.

Please note that this appendix does not represent a complete list of all the existing software for the various tasks listed here. It is intended to provide a general overview of the different corpora and specifications available, to give you an idea of what resources you can use in your own annotation and machine learning (ML) tasks. For the most up-to-date list of resources, check the LRE Resource Map, or just do a web search to see what else is available.
