An Ontology-Driven Life-Event Portal

The goal of this project is to provide the user of an e-government portal, exposed by a given public agency, with the ability to modify personal information upon occurrence of a life-event, and to alleviate the redundancy inherent to the process. A change of address for example, which must be acknowledged by several agencies, should be notified once using a portal; agencies related to this service would be informed of its occurrence and only missing or ambiguous data will be requested. To achieve this in a maintenable way the whole process should be ontology-driven (Guarino, 1998) meaning that data is mapped according to semantic specifications and that the portal is directly based on an ontology. In order to achieve ontologybased software development and to ensure interaction between the various components, additional knowledge modelling techniques presented independently in (Tanasescu et al., 2004) were introduced.
