These topics are also related to the field of artificial intelligence; the main principles and mathematical foundations of their general tool sets hardly differ from that of other intelligent computer methods. However, due to the practical significance and special characteristics of the tasks, they are treated as separate disciplines. The speciality of pattern recognition is related to the physics and psychology of perception, and robots use partly these special pattern recognition skills, and partly the structural and dynamics-related results of mechanics.
Computational linguistics has become an independent discipline, with subfields such as natural language processing, machine translation or several investigations on huge amounts of texts.
Cognitive sciences, i.e. the multidisciplinary fields of artificial systems, neurology and psychology, also come under this category.
Our initial proposition held that everything is a system. Our closing proposition, however, reveals that the sciences dealing with such systems are boundless and interminable.
