[CWB] Virtual seminar POSTPONED: Embedding CWB in a CL Workflow | Finite State Queries

[Stefan Evert]

Unfortunately, the CWB virtual seminar announced a last week has to be postponed.  The new data will be 

	Wednesday, 17 February 2021, 16:15–17:45 CET

Further registrations for the new date to obtain the Zoom link (free of charge, of course) are still welcome.

Best,
Stefan
