Our research involvement includes “Integrated European Industrial Risk Reduction System (IRIS)”, an integrated project supported by the European Community under the Seventh Framework Programme (Nanosciences, Nanotechnologies, Materials and new Production Technologies, FP7-NMP-2007-LARGE-1, CP-IP 213968-2). This project integrates various aspects of industrial safety in different domains (nuclear, chemical, construction, energy production, mining and oil industries) with priority on saving human lives and prior cost reductions. One of its targets is to support risk informed engineering design by knowledge and technologies for risk identification and reduction. In short the concept of IRIS is to focus on diverse industrial sector’s main safety problems as well as to transform its specific requirements into integrated and knowledge-based safety technologies, standards and services. Our main concern is the ontology-based document retrieval and knowledge-based support in selected IRIS domains.
Current research interests are also concentrated to the European project “NETCARITY”, Integrated Project supported by the European Community under the Sixth Framework Programme (Information Society Technologies, Ambient Assisted Living, IST-2006-045508). This project is focused on research and testing of technologies which help older people to improve their wellbeing, independence, safety and health at home. Our main concern is the central server with enterprise Java and relational database, secure and reliable messaging channel between homes and the server, and communication between the NETCARITY clients and external service providers.
Semantic web and ontologies were studied in the EC project "Enabling Communities of Interest to Promote Heritage of European Regions (CIPHER)", in the period 2002 - 2004. Its type was IST RTD, Key Action "Heritage for All". Project tasks included global heritage exploration in virtual Cultural Heritage Forums, ontology driven dynamic personalized narratives, information visualization, adaptive delivery to mobile and fixed technologies, collaborative discovery tools, multilingual access and the test case "Long common history of Southern Bohemia and Upper Austria regions".
In the OLAP area our interest is focused on a general approach to the problem of data warehouse design and updating (a periodical data gathering, transformation, unification and its addition into a data warehouse). Mainly the problems of generalized data pump are identified, studied and solved. The main focus is concentrated on describing and handling of uncertainty, which comes from merging imperfect data sources. Uncertainty measures and their implementation approaches are suggested. Our activities are influenced by the results of the GOAL project - a research project funded by the European Commission COPERNICUS program. Within the GOAL project, our aim was to develop an integration module making possible to integrate the data warehouse with a geographical information system. The GIS systems play both the role of data source feeding the data warehouse with data and the role of presentation platform for OLAP analysis. For more detailed information see the project page: "GOAL - GEOGRAPHIC INFORMATION ON-LINE ANALYSIS".
In the OLTP area our interest is focused mainly on information system design and process modeling. The results were applied in a project developed for Ministry of Culture of Czech Republic (1996-1998): For more detailed description of this project see the project page: "COMPUTERISED INVENTORY RECORD KEEPING IN HISTORICAL BUILDINGS". The system developed within this project aims to handle the whole agenda concerning the care for movable historical objects like various kinds of arts (china, pictures, arms, curtains, etc.). The agenda is quite complex - it includes plans of repairs, keeping track of transfers of inventory items to exhibitions, renting them e.g. to movie production companies, etc. An important feature of the system is the supposed automatic identification of inventory items based in the simplest case on bar code, in more advanced case on radio frequency based methods of identification.
