Geospatial image data obtained by satellites and aircraft are increasingly important to a wide range of applications, such as disaster management, climatology, and environmental m...
Abstract. In this paper, we focus on B2B scenarios where XML views are extracted from relational databases and sent over the Web to another application that edits them and sends th...
Regular path queries are the basic navigational component of virtually all the mechanisms for querying semistructured data commonly found in information integration applications, W...

We consider the problem of querying XML documents which are not valid with respect to given DTDs. We propose a framework for measuring the invalidity of XML documents and compactly...
Users without knowledge of schemas or structured query languages have difficulties in accessing information stored in databases. Commercial and research efforts have focused on key...
The wavelet decomposition is a proven tool for constructing concise synopses of massive data sets and rapid changing data streams, which can be used to obtain fast approximate, wit...
In my thesis I will address the problem of interoperation between information spaces on the web. We explain how this problem is different to traditional database integration scenar...
Abstract. We discuss, compare and relate some old and some new models for incomplete and probabilistic databases. We characterize the expressive power of c-tables over infinite dom...
Abstract. The Semantic Web is based on XML and RDF as its fundamental standards for exchanging and storing information on the World Wide Web. Event-condition-action (ECA) rules are...
