In this paper we present a thorough evaluation of a corpus resource for Portuguese, CETEMPúblico, a 180million word newspaper corpus free for R&D in Portuguese processing. We provide information that should be useful to those using the resource, and to considerable improvement for later versions. In addition, we think that the procedures presented can be of interest for the larger NLP community, since corpus evaluation and description is unfortunately not a common exercise. | Evaluating CETEMPúblico a free resource for Portuguese Diana Santos SINTEF Tele og Data Postboks 124 Blindern N-0314 Oslo Norway Diana.Santos@informatics.sintef.no Paulo Rocha Departamento de Informática Universidade do Minho PT-4710-057 Braga Portugal Paulo.Rocha@alfa.di.uminho.pt Abstract In this paper we present a thorough evaluation of a corpus resource for Portuguese CETEMPúblico a 180million word newspaper corpus free for R D in Portuguese processing.

In our opinion that is the wrong conclusion. There is in fact a lot to be said about any particular corpus. We believe in addition that such information should be available when one is buying or even just
