TSNLP (Klaus Netter, Doug Arnold, Stephan Oepen)
`Test Suites for Natural Language Processing' is a European consortium providing NLP test suite technology and test suite fragments for German, French and English. For a description of the TSNLP annotation scheme, see their WP2.2. See section 5 for examples. The annotation scheme includes sentential information (such as a well-formedness score) and also word and sub-string annotation which is stored in tabular form (for analytical information including syntactic constituents and error descriptions). There is a web interface to the test suites. The database schema is described in the user manual, volume 2, section 4.
