An Efficient One-Scan Sanitization For Improving The Balance Between Privacy And Knowledge Discovery
Download2003
Oliveira, Stanley, Zaiane, Osmar
Technical report TR03-15. In this paper, we address the problem of protecting some sensitive knowledge in transactional databases. The challenge is on protecting actionable knowledge for strategic decisions, but at the same time not losing the great benefit of association rule mining. To...

Benchmarking Access Structures for High-Dimensional Multimedia Data
1999
Nascimento, Mario, Colossi, Nathan
Technical report TR99-05. In multimedia databases it is usual to map objects into feature vectors in high-dimensional spaces. In order to speed query processing access structures, or indices, are required. Unfortunately, in the case of similarity queries, which are in fact nearest neighbor ...

Inverted Matrix: Efficient Discovery of Frequent Items in Large Datasets in the Context of Interactive Mining
Download2003
El-Hajj, Mohammad, Zaiane, Osmar
Technical report TR03-08. Existing association rule mining algorithms suffer from many problems when mining massive transactional datasets. One major problem is the high memory dependency: either the gigantic data structure built is assumed to fit in main memory, or the recursive mining process...

A Generic Type System for an Object-Oriented Multimedia Database System
1996
Technical report TR96-14. This Technical Report is based upon an M.Sc. thesis in the Department of Computing Science at the University of Alberta. It describes the design of a generic multimedia database system that supports a wide class of documents. The design is characterized by an...

Goralwalla, Iqbal, Ozsu, M. Tamer, Tansel, Abdullah
Technical report TR94-15. In this paper we describe an implementation of a temporal relational database management system based on attribute timestamping. For this purpose we modify an existing software which supports set-valued attributes. The algebraic language of the system includes...

Niedermayer, Johannes, Nascimento, Mario A., Kroeger, Peer, Kriegel, Hans-Peter, Renz, Matthias
Technical report TR10-03. Top-k queries are a popular type of query in Wireless Sensor Networks. Typical solutions rely on coordinated root-to-nodes and nodes-to-root messages and on maintaining filters at the nodes, aiming at suppressing unnecessary messages, hence saving energy and furthering...
