The Academia das Ciências de Lisboa (ACL) is one of the oldest national scientific institutions, existing since December 24, 1779, when it was founded during the reign of Queen Maria I, under Fedro’s motto: Nisi utile est quod facimus stulta est gloria. [Glory is vain if what we do is useless.]

Through the Instituto de Lexicologia e Lexicografia da Língua Portuguesa (ILLLP), the ACL has the following lexicographic activities undergoing:

• Portuguese Academy Dictionary: The latest edition of the Portuguese Academy Dictionary (2001) is being updated (the electronic version of the DACL is not publicly available yet). The project is coordinated by Ana Salgado with the consultancy of Álvaro Iriarte Sanromán from Minho University. The Natural Language Processing group of the Computer Science Department of the University of Minho (Alberto Simões and J. J. Almeida) has been developing the technological support which now counts with the participation of NOVA CLUNL (Linguistic Research Center of NOVA University of Lisbon).
