Every even-numbered year, ECCAI, jointly with one of the member associations of ECCAI, organizes a European Conference on AI. This conference, abbreviated ECAI, has become the leading conference for this field in Europe. The list of ECAI proceedings is available here.
In retrospect, the first ECAI meetings were considered to have been the AISB conferences: Brighton (1974), Edinburgh (1976), Hamburg (1978), Amsterdam (1980). Conferences using the name ECAI have been held in Orsay (1982), Pisa (1984), Brighton (1986), Munich (1988), Stockholm (1990), Vienna (1992), and Amsterdam (1994).
