The Role of Evaluation in Language Technology

Spelling checkers, natural language interfaces and machine translation systems (MT) have something in common: they belong to the group of natural language processing systems and there is no doubt, that the theoretical basis of these systems is called computational linguistics. This basis has its roots in linguistics, i.e. in formal linguistics, in mathematics and computer science. Furthermore, there are influences from sociology, psychology and the interdisciplinary fields among these five. Computer science with its subfields hardware and software is the only candidate which could contribute to a technology.
