The department has active contacts with many European and American computer science departments. Faculty members have joint research efforts with individual researchers from abroad. The results of this international cooperation are partly presented in the publication list. Many faculty members have spent long periods of time abroad as visiting researchers or guest professors. In turn, apart from more than 20 short term visitors every year, the department has hosted several visiting foreign scholars. A list of long term visitors in 1996-98 is given below.
The department has actively taken part in the European research cooperation. The department has participated in the COST 247 project Formal methods in Communication Protocol Design.
The department has also taken part in the ESPRIT Programme in several projects. The largest of these are KESO - Knowledge Extraction for Statistical Offices (ESPRIT III 20596, Heikki Mannila, 1996-98) and TransCoop - Transaction Management Support for Cooperative Applications (ESPRIT III P8012, Henry Tirri, 1994-97). The department is a member institution in the working group NEUROCOLT II - Neural and Computational Learning (ESPRIT Working group EP 27150, Esko Ukkonen, 1994-) and in networks of excellence like ML-net - Network of excellence in Machine Learning (ESPRIT III P7115, Esko Ukkonen, 1994-) and NEURONET - Network of excellence in Neural Networks (ESPRIT III P8961, Henry Tirri, 1994-).
In addition the department is a member institution of EC ACTS-project DOLMEN Service Machine Development for an Open Long-Term Mobile and Fixed Network Environment (AC036, Kimmo Raatikainen, 1995-98). The project Object-oriented programming and compiler construction (Jukka Paakki, 1995-97) was funded jointly by the Academy of Finland and Deutscher Akademischer Austauschdienst.
