Using the GRID for biodiversity research: the GRAB demonstrator
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 11-14
A.C. Jones, J.S. Robinson, W.A. Gray, J.P. Giddy, N.J. Fiddian
In the GRAB (Grid and Biodiversity) project we are developing a prototype to illustrate some aspects of the GRID's potential for collaborative biodiversity research. A catalogue of life, two species information systems (SISs) and a climate database are made available in a problem solving environment that demonstrates how bioclimatic modelling can be performed by bringing together such resources.

Similarity searching for multi-attribute sequences
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 175-184
T. Kahveci, A. Singh, A. Gurel
We investigate the problem of searching similar multiattribute time sequences. Such sequences arise naturally in a number of medical, financial, video, weather forecast, and stock market databases where more than one attribute is of interest at a time instant. We first solve the simple case in which the distance is defined as the Euclidean distance. Later we extend it to shift and scale invariance...... hiện toàn bộ

Joint queries estimation from multiple OLAP databases
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 241
E. Pourabbas, A. Shoshani
Given an OLAP query expressed over a collection of source OLAP databases, we study the problem of computing the result OLAP target database when the underlying detail data of the source databases are not available. The problem arises when the source databases do not have the same category attributes, and it is not possible to derive the result from a single database. The method we use is the linea...... hiện toàn bộ

Image data model for an efficient multi-criteria query: a case in medical databases
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 165-174
R. Chbeir, S. Atnafu, L. Brunie
Since the last two decades, image database management has been practiced using different image representation methods. In the literature, images are represented using two paradigms: the metadata-based and the content-based representations. Image retrieval using the metadata is done using the traditional database operations. However, image retrieval by its low-level features requires similarity-bas...... hiện toàn bộ

Query processing with description logic ontologies over object-wrapped databases
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 27-36
M. Peim, E. Franconi, N.W. Paton, C.A. Goble
This paper presents an approach to answering queries over an ontology modelled using a description logic. The ontology acts as a global schema, providing a declarative description of the concepts of the domain, the instances of which are stored in (potentially many) object-wrapped sources. Queries are expressed using terms from the rich vocabulary of the ontology, and are translated into an equiva...... hiện toàn bộ

Abstract and discrete models for uncertain spatiotemporal data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 240
E. Tossebro, M. Nygard
Summary form only given. We deal with the uncertainty in spatial and spatiotemporal databases. Due to lack of accurate measurements, or rapid changes in time, spatial and spatiotemporal data are often uncertain. Our work presents new abstract and discrete models for uncertain spatial and spatiotemporal information. The models are based on the principle that one knows that the uncertain object, reg...... hiện toàn bộ

Metadata for traveling statistics-the world of statistics meets the semantic Web
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 191
J. Ryssevik
Summary form only given. The paper focuses on the requirements of metadata in a world where the Internet and the Web have become the dominant communication and dissemination medium for statistical information. Four important aspects of metadata (finding, understanding, assessing and sharing) are discussed in the light of this development. Special focus is on the ideas and concepts of the semantic ...... hiện toàn bộ

Use of metadata registries for searching for statistical data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 232-235
C. Nelson
The Internet has spawned an insatiable appetite for information. This appetite cannot be satisfied without useful search tools. These tools rely on metadata in order to give targeted and meaningful results to searches, and the Internet world is realising that metadata, its management, and the means to search these metadata, are an integral part of the Internet world. The EC 5th Framework project C...... hiện toàn bộ

Chimera: a virtual data system for representing, querying, and automating data derivation
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 37-46
I. Foster, J. Vockler, M. Wilde, Yong Zhao
A lot of scientific data is not obtained from measurements but rather derived from other data by the application of computational procedures. We hypothesize that explicit representation of these procedures can enable documentation of data provenance, discovery of available methods, and on-demand data generation (so-called "virtual data"). To explore this idea, we have developed the Chimera virtual...... hiện toàn bộ
