Abstract

Controlled vocabularies are ubiquitous in varied application fields. They are particularly helpful in the medical field since they can unify disparate terminologies and provide information in a compact, comprehensible manner. In this thesis, we present a mechanism to efficiently retrieve and update knowledge stored in a controlled vocabulary modeled as an Object-Oriented Database (OODB) system. We aim to provide a standardized interface to the vocabulary, such that the implementation details of the vocabulary are transparent to all users. The user of this standardized interface will typically be an application programmer who is trying to provide the vocabulary's knowledge-base to end users. We first describe our approach to creating the standardized interface. We then present the software architecture and design for it. We conclude by describing the implementation of this standardized interface.
