The Machine Intelligence 14 workshop was generously supported by the Daiwa Anglo-Japanese Foundation under an agreement concluded in 1991 between the Turing Institute, UK and the Japan Society for Artificial Intelligence, Tokyo. The Foundation provided funding, covering Workshops 13 and 14, to defray travel and attendance costs for six Japanese and six British scientists nominated by the respective parties. The Daiwa Anglo-Japanese Foundation has recently announced its intention to extend its support to Workshop 15, which will be held in July 1995 at St. Catherine's College Oxford. Hitachi kindly provided support and facilities by allowing the Machine Intelligence 14 workshop to be held at its spacious Advanced Research Laboratory near Tokyo. Like its predecessor, Machine Intelligence 13, this volume reflects the vigour with which the subject is being advanced in Japan. Thanks are also due to the Oxford University Computing Laboratory for kindly allowing use of printing and document preparation facilities in the production of this volume.
