Preface

The International Conference on Computational Processing on Portuguese, formerly the Workshop on Computational Processing of the Portuguese Language – PROPOR – is the main event in the area of Natural Language Processing that focuses on Portuguese and the theoretical and technological issues related to this specific language. The meeting has been a very rich forum for the interchange of ideas and partnerships for the research communities dedicated to the automated processing of the Portuguese language. This year’s PROPOR, the first one to adopt the International Conference label, followed workshops held in Lisbon, Portugal (1993), Curitiba, Brazil (1996), ´ Porto Alegre, Brazil (1998), Evora, Portugal (1999), Atibaia, Brazil (2000), Faro, Portugal (20
