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...

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...

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...

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...

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...

Thiết kế và triển khai ngôn ngữ truy vấn dữ liệu dựa trên nghĩa Dịch bởi AI
- Trang 20-23
Chúng tôi trình bày thiết kế và triển khai một ngôn ngữ truy vấn dữ liệu dựa
trên nghĩa - MDDQL - nhằm mục đích xây dựng các truy vấn thông qua những gợi ý
từ hệ thống về các thuật ngữ truy vấn dựa trên ngôn ngữ tự nhiên cho cả lĩnh vực
ứng dụng khoa học và các thuật ngữ toán tử/hoạt động. Một bảng đen xây dựng truy
vấn được sử dụng, nơi các thuật ngữ ngôn ngữ truy vấn được gợi ý cho người dùng

Statistical composites: a transformation-bound representation of statistical datasets
- Trang 217-226
Statistical data processing makes use of data matrices and tables as primary
structures for data representation. Embedding these structures into
processing-relevant context information gives rise to enhanced data structures
linking data and metadata. The paper describes a framework for statistical data
processing utilising metadata computationally.

Các yêu cầu dữ liệu đang thay đổi nhanh chóng của môi trường kinh doanh động
hiện nay không được xử lý tốt bởi các hệ thống xử lý phân tích trực tuyến (OLAP)
hiện tại. Việc tích hợp dữ liệu từ các nguồn mới vào các hệ thống OLAP một cách
vật lý là một quá trình lâu dài và tốn thời gian, khiến việc tích hợp logic trở
thành lựa chọn tốt hơn trong nhiều tình huống. Việc sử dụng Tài liệu Đánh dấu Mở

Multiple overlapping classifications: issues and solutions
- Trang 77-86
This paper discusses issues and solutions for supporting multiple overlapping
classifications in database systems. These classifications are commonly found in
science, although they are often ignored in computing applications for
scientific data, and inappropriate solutions adopted as their replacement. Known
database models and classification techniques offer some degree of support for
multiple o...

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...
