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...

Information-theoretic disclosure risk measures in statistical disclosure control of tabular data
- Trang 227-231
Statistical database protection is a part of information security which tries to
prevent published statistical information (tables, individual records) from
disclosing the contribution of specific respondents. This paper shows how to use
information-theoretic concepts to measure disclosure risk for tabular data. The
proposed disclosure risk measure is compatible with a broad class of disclosure
pr...

Annotating scientific images: a concept-based approach
- Trang 59-68
Data annotations are an important kind of metadata that occur in the form of
externally assigned descriptions of particular features in Web accessible
documents. Such metadata are eventually used in data retrieval tasks on
heterogeneous, possible distributed Web-accessible documents. In this paper, we
present the model and realization of an annotation framework that scientists can
employ to semant...

Similarity searching for multi-attribute sequences
- 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...

Access Support Tree and TextArray: a data structure for XML document storage and retrieval
- 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...

Accelerating high-dimensional nearest neighbor queries
- Trang 109-118
The performance of nearest neighbor (NN) queries degrades noticeably with
increasing dimensionality of the data due to reduced selectivity of
high-dimensional data and an increased number of seek operations during NN-query
execution. If the NN-radii were known in advance, the disk accesses could be
reordered such that seek operations are minimized. We therefore propose a new
way of estimating the ...

The Edinburgh mouse atlas and gene-expression database: a spatio-temporal database for biological research
- Trang 239
The Edinburgh Mouse Atlas Project (EMAP) has developed a digital atlas of mouse
development which provides a bioinformatics framework to spatially reference
biological data. The EMAP core database contains 3D grey-level reconstructions
of the mouse embryo at various stages of development, a systematic nomenclature
of the embryo anatomy, and defined 3D regions (domains) of the embryo. The
reconstru...

A cost model for interval intersection queries on RI-trees
- Trang 131-141
The efficient management of interval data represents a core requirement for many
temporal and spatial database applications. With the relational interval tree
(RI-tree), an efficient access method has been proposed to process interval
intersection queries on top of existing object-relational database systems. The
paper complements that approach by effective and efficient models to estimate
the sel...

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...
