Improving efficiency of information systems with ontology-based information complement method

Pospishnyi O.S.

The article presents a formal description of an information system and proposes a method for quantifying an amount of information that it stores and processes. A notion of complemented information systems is being considered, in which additional implicit information is extracted from the stored data based on its semantics. We discuss an application of ontologies to the task at hand, proving their effectiveness as an information complementing tool. We propose a new method to substantially reduce the complexity of quires to the information system and considerably simplify user’s interaction with it. A suggestion is made to perform a preventive logical validation of incoming queries to the information system to further increase their effectiveness. Keywords: information systems, ontology, amount of information, information retrieval.
