We present a novel approach for the automatic generation of model-to-model transformations given a description of the operational semantics of the source language by means of graph...
We dene a preferential semantics based on stable generated models for a very general class of temporal deductive databases. We allow two kinds of temporal information to be repre...
For data to be successfully integrated, semantically similar database elements must be identified as candidates for merging. However, there may be significant differences between ...
Abstract. We study here fundamental issues involved in top-k query evaluation in probabilistic databases. We consider simple probabilistic databases in which probabilities are asso...
This paper presents a new method for image retrieval using a graph object oriented database for processing the information extracted from the image through the segmentation process...
