A critical issue in moving object databases is to develop appropriate indexing structures for continuously moving object locations so that queries can still be performed efficien...
This paper presents an approach to realize a case retrieval engine on top of a relational database. In a nutshell the core idea is to approximate a similarity-based retrieval with ...
In this paper we consider the problem of efficiently producing results for full-text keyword search queries over XML documents. We describe full-text search query semantics and pr...
Efficient indexing techniques have been developed for the exact and approximate substructure search in large scale graph databases. Unfortunately, the retrieval problem of structu...
In this paper, we present and evaluate alternative techniques to effect the use of location-independent identifiers in distributed database systems. Location-independent identi...
