This work proposes the creation of an ontological framework from Colombian orchids for an Intelligent Search System that could be used by members of botanic research centers and software agents interested in sharing their knowledge. The computational ontology lets to classify the orchid species presents in Colombia on a semantic level, identifying and semantically distinguishing (through axioms and rules) the genera of the Orchidaceae family. The ontology is based on the observable features presents in each plant (Top level concepts), their classification, preservation and general properties. Protege, Racer and Prolog are the development tools employed for creating the prototype that uses the defined ontology for performing intelligent searches, identifying and classifying the Orchids.
