Objective
IRAIA is a design solution for software agent repositories establishing an information retrieval service. Retrieval takes place in a semantic co-ordinate system presented by information visualisation maps. This system of orientation is based on ontologies that result from the collaborative effort of analysts from different disciplines as well as from analysed search strategies (including personalisation of profiles of usage).
OBJECTIVES
IRAIA is an approach for new information technology that:
- investigates the navigation behaviour of users, takes this information as feedback and combines it with other modes of feedback to profiles of usage (maps of footsteps), in order to provide suggestions to the users for their further navigation;
- provides a semantic coordinate system presented by visualisation maps that enables the users always to keep up with their orientation in the information space;
- applies agent technology to this advanced approach to information retrieval in order to establish flexible, interoperable, scalable, and federated information repositories that are easily adaptable to new emerging information sources, architectures and infrastructures.
DESCRIPTION OF WORK
Information retrieval systems of the future will be a huge amount of information repositories distributed over the world. And even the users will contribute to these repositories by communicating their experiences to other users who follow their footsteps. IRAIA?s design metaphor focuses on the ants? system for communicating information. Navigating the Web should allow people to leave pointers for those who might also navigate along the same paths. IRAIA presents the information space in a coordinate system that enables them to have a clear orientation during the retrieval process. Information infrastructure is not only a technical challenge but also the result of a corporate effort of various domain-specific and content-related organisations together with teusers.
The growth of the Internet and the inherent volatility of complex information spaces require a new model of software. By this dynamic trait only a system of software agents can react adequately to changes in large, complex, and volatile information saces. It will be realised in an environment of distributed and CORBA-based software agents. One part of these Information Agents enables users to navigate the Web within a semantic coordinate system that provides them with orientation. The other par is in harge of data refinement, based on the methods of information retrieval.
On the level of abstraction they establish different layers of data refinement each of them adding a certain value to the system of orientation. In particular, IRAIA focuses n inorpoating profiles of usage into the level of abstractions. IRAIA is a research project that develop real-world testbeds used by actual users and by aiming at developing new, comprehensive, and user-friendly technologies. Its testbeds provide information the economy which comes from large databases of Economic Research Institutes and National Statistical Institutions.
The numerous developments achieved in the study of the bentonite barriers for deep radioactive waste disposal have been analysed and integrated. Current repository concepts have been reviewed and reference cases have been selected for modelling. Four reference cases, covering the scope of the project, have been set using the repository concepts for ENRESA 2000, KBS-3V, Boom Clay and Opalinus Clay. A review of all the features, events and processes (FEPs) relevant to the performance of bentonite barriers has been carried out. Two BENIPA reference FEPs databases, differentiated for granite and clay, have been completed. The project has analysed the information (studies, experiments findings and conclusions, data) available related to bentonite barriers. Results of the analysis have been compiled and elaborated further for clay and granite media. The descriptions of the different models and computer codes to be used, both at a detailed process level and at integrated level, for the numerical simulation of the behaviour and performance of bentonite barriers have been compiled and the capacity of characterisation methods and measuring techniques to satisfy the input requirements have been analysed. Different types of calculations have been performed at process level and integrated level using all the available codes in the project. The results have been analysed, compared and discussed to draw conclusions. A second set of numerical experiments were defined and performed and the results analysed to investigate the sensitivity and margins of optimisation of bentonite barrier performance.
