Efficient techniques for range search queries on earth science data
- 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...

Using the GRID for biodiversity research: the GRAB demonstrator
- 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. W...

Chimera: a virtual data system for representing, querying, and automating data derivation
- Trang 37-46
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...

An architecture for managing distributed scientific resources
- Trang 47-55
There are many examples where cooperation among scientists takes place by
exchanging scientific resources, such as data, programs and mathematical models.
This is particularly true for environmental applications. Finding the right
resource to apply in an environmental problem is a difficult task. Usually, this
decision is based on previous experience. Scientists have to cooperate in order
to solve...

Compressing bitmap indexes for faster search operations
- Trang 99-108
We study the effects of compression on bitmap indexes. The main operations on
the bitmaps during query processing are bitwise logical operations. Using the
general purpose compression schemes the logical operations on the compressed
bitmaps are much slower than on the uncompressed bitmaps. Specialized
compression schemes, like the byte-aligned bitmap code (BBC), are usually faster
in performing lo...

Tale of two cultures: are there database research issues in bioinformatics?
- 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...

A structure-based search engine for phylogenetic databases
- 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...

Joint queries estimation from multiple OLAP databases
- Trang 241
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...

Abstract and discrete models for uncertain spatiotemporal data
- 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...
