Machine processing of natural languages has been a difficult problem in the intelligent systems research area for the last four decades. Early approaches to machine processing of natural languages failed, partly because of interaction effects of complex phenomena that made the machine process appear to be unmanageable. Recent approaches to the problem have been more successful but are limited on many language-specific rules related to rigid word order of the languages. Many machine processing systems depend heavily on the language-specific rigid word order. The problem addressed in this paper is the construction of a machine processing system relying on language-specific imprecise computations. This paper presents an alternative approach to machine processing of natural languages. The system relies on interchangeable phrases and flexible word order. The application of imprecise computation for machine translation problems is approached by examining Sinhalese. The design and implementation of the system are described and illustrated with detailed examples of overall system operation.
