Introduction,ta on the Web, in such a way that it can be employed by machines for automation, integration and reuse across various applications, has been exploited in several research fields. However, the gigantic amount of such useful information makes more and more difficult its efficient management, undermining the possibility to transform it into useful ..

Preserving Semantics in Automatically Created Ontology Alignmentsept in different application domains or because of different ontology design styles which often produce incompatible ontology structures. In this chapter, we relate the most important approaches to ontology mapping revision, proposing a revision technique which aims at preserving the semantics of the original ontologies.

Reasoning in Semantic Web-based Systemsning they typically facilitate. Based on this, we proceed to focus on concrete reasoning techniques and their particular properties, including optimizations and various other possibilities, e.g., parallelization and approximation, to meet the scalability requirements in Web-based systems.

The underlying idea of having a description of the data on the Web, in such a way that it can be employed by machines for automation, integration and reuse across various applications, has been exploited

Data and Metadata Management,how they are handled within dictionaries in relational databases. We then address, from a general point of view, the notion of data model as a means for the representation of information at different levels of details, and show how dictionaries can be used to manage schemas of different data models.
