Ontology translation agent can fulfills two rules, so that
meet the requirement of interoperation between
distributed ontological repository: translation rules, is the
rule of knowledge expression of the local ontological
repository are translated into common language of
ontology translation agent, by which knowledge that can
interact each other in a manner of standard and consistent
communication; mapping rules, is the rule of terminology
of the local ontological repository are mapped into
common vocabularies in a way of tree structure of
ontology translation agent, by which provide further
classification and reasoning of domain howledge.
