We describe a class of applications which are built using databases comprising some structured data and some free text. Conventional database management systems have proved ineffective for these applications and they are rarely suitable for current text and data mining techniques. We argue that combining Information Extraction and Data Integration techniques is a promising direction for researc...

Increasing social, economic and environmental pressure force the process industry to look for new ways to improve the overall operation of their process systems.Since these systems are operated at different levels of decision (apparatus, plant, enterprise, etc.) integration of the different levels is expected to lead to significant improvements in system efficiency (energy, waste, costs, qualit...

In this paper Word Sense Disambiguation (WSD) issue in the context of data integration is outlined and an Approximate Word Sense Disambiguation approach (AWSD) is proposed for the automatic lexical annotation of structured and semi-structured data sources.

It is often useful to apply several speciication techniques within the same software development project. This raises the question how speciication techniques can be integrated. In this presentation we give three diierent examples of how this can be done. In the rst example, we summarise how the wide-spectrum approach has been used in the RAISE Speciication Language (RSL) to integrate algebraic...

Accessibility for Conventional Applications Integrating KBSs with simulations, databases, and other conventional applications increases the audience for these applications. Several simulations developed within academic and research organizations have not been used to their potential because they are difficult to apply. Even when such models and simulations are used, the danger exists of their b...

Grids are distributed systems that provide access to computational resources in a transparent fashion. Providing information about the status of the Grid itself is called Grid monitoring. As an approach to this problem, we present the Relational Grid Monitoring Architecture (R-GMA), which tackles Grid monitoring as an information integration problem. A novel feature of R-GMA is its support for ...

AbstrAct The semantic Web suggests to annotate Web resources with machine-processable metadata; and on-tologies, as means to conceptualize and structure knowledge, are seen as the key to realize the vision of the semantic Web. However, ontologies themselves do not provide semantic interoperability, since a single ontology cannot be used to represent all kinds of domains and applications. Ontolo...

Database integration provides integrated access to multiple data sources. Database integration has two main activities: schema integration (forming a global view of the data contents available in the sources) and data integration (transforming source data into a uniform format). This paper focuses on automating the aspect of data integration known as entity identification using data mining tech...
