Abstract and discrete models for uncertain spatiotemporal data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 240
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

Using the GRID for biodiversity research: the GRAB demonstrator
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 11-14
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.

Efficient techniques for range search queries on earth science data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 142-151
We consider the problem of organizing large scale earth science raster data to efficiently handle queries for identifying regions whose parameters fall within certain range values specified by the queries. This problem seems to be critical to enabling basic data mining tasks such as determining associations between physical phenomena and spatial factors, detecting changes and trends, and content b...... hiện toàn bộ

A structure-based search engine for phylogenetic databases
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 7-10
Phylogenetic trees are essential for understanding the relationships among organisms or taxa. Many of the current techniques for searching phylogenetic repositories allow the user to perform a keyword-type search or an aligned sequence data search, or to browse a hierarchical list of taxa. Here we describe a new search engine that allows the user to present an example phylogeny, or a query tree, a...... hiện toàn bộ

A conceptual framework for composing and managing scientific data lineage
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 15-19
Scientific research relies as much on the dissemination and exchange of data sets as on the publication of conclusions. Accurately tracking the lineage (origin and subsequent processing history) of scientific data sets is thus imperative for the complete documentation of scientific work. However, the lack of a definitive data model for lineage, and the poor fit between current data management tool...... hiện toàn bộ

Tale of two cultures: are there database research issues in bioinformatics?
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 3
It was the best of times, it was the worst of times, it was the age of biology, it was the age of computer science, it was the epoch of whole-genome sequencing, it was the epoch of high performance computing, it was the season of ab-initio discoveries, it was the season of in-silico predictions, it was the spring of mass data production, it was the winter of interoperability, we had everything bef...... 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
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

Access Support Tree and TextArray: a data structure for XML document storage and retrieval
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 155-164
The characteristics of XML documents require new ways of storing and querying such documents. Queries on both textual content and structural aspects must be supported efficiently. For this reason, we examined existing work on both document storage approaches and models for querying documents to derive requirements that are essential for the storage of XML documents. As a result of our study, we de...... hiện toàn bộ

Similarity searching for multi-attribute sequences
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 175-184
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
