WP10: Case study eBanking D10. 3 Financial Ontology

This document describes the financial ontology that has been created for Bankinter for the first eBanking case study in DIP, which is described in the deliverable D10. 2. This application consists of a mortgage simulation and comparison service. The financial ontology consists of several ontologies at different levels of abstraction: services and products; and channels, users and currencies. All of them are described in section 4. The ontology does not aim at covering the whole financial domain but focuses mainly on modelling conceptually the mortgage domain (the first application to be developed in the workpackage). The ontology has been designed to be modular enough to allow refinements in the context of the current domain and extensions to other domains in the financial area.We explain the reasons why it is difficult to build an ontology that covers the complete financial domain, including previous standardization experiences and business aspects. The financial ontology has been developed following the Methontology methodology [4]. For the specification phase we have used a technique proposed in the context of the kick-off phase of the On-to-knowledge methodology [9], which has proven to be useful to obtain the initial set of concepts and relations, and their classification, from nonexperts in knowledge representation.
