Human possess inherent capabilities to store, processes and reason on imprecise information in the form of perceptions in natural language. Generalized theory of uncertainty (GTU) is a methodology for reasoning, representing, and performing computations on such imprecise information. Generalized constraint, the basic data structure in GTU, is used to represent and propagate information. There is no previous attempt to implement this theoretical methodology. This paper reports the implementation of a Java API toolkit for generalized constraint language (GCL) that can be easily expanded for practical applications of GTU in the form of an expert system. Toolkit allows users to express various types of GTU concepts, such as generalized constraint, fuzzy graphs, fuzzy relations, and fuzzy arithmetic expression. Toolkit is fully integrated with Jess (Java Expert System Shell) and utilizes Jess Rete network for deductions on generalized constraints.
