Ontological Approach to Viable Decision Support Services Development

Abstract

The concept and the technology for creation and maintenance of decision support services based on knowledge bases are described. The ontological approach for knowledge, data and solver formation, along with the principle of reusability and extensible tools provide the viability for such services. An important issue is a unified representation and storage for service components of all typesboth information and software ones. It allows to involve experts and knowledge engineers into development process on par with programmers and to use alike tools for creation of service components. Another significant requirement is a multi-user access for tools and components, preferably a cloud oneover the Internet. This eases the control of service development and allows to store and update components with no need of redistribution afterwards. The implementation of the described technology and tools on the IACPaaS cloud platform is presented with examples of medical knowledge portal and its fractions.
