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

Thiết kế và triển khai ngôn ngữ truy vấn dữ liệu dựa trên nghĩa Dịch bởi AI
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 20-23
E. Kapetanios, D. Baer, P. Groenewoud, P. Mueller
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 bằ...... 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
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.

Information-theoretic disclosure risk measures in statistical disclosure control of tabular data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 227-231
J. Domingo-Feffer, A. Oganian, V. Torra
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...... hiện toàn bộ

Statistical composites: a transformation-bound representation of statistical datasets
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 217-226
M. Denk, K.A. Froeschl, W. Grossmann
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.

A structure-based search engine for phylogenetic databases
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 7-10
Huiyuan Shan, K.G. Herbert, W.H. Piel, D. Shasha, J.T.L. Wang
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

Efficient techniques for range search queries on earth science data
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 142-151
Qingmin Shi, J.F. JaJa
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 cost model for interval intersection queries on RI-trees
Proceedings 14th International Conference on Scientific and Statistical Database Management - - Trang 131-141
H.-P. Kriegel, M. Pfeifle, M. Potke, T. Seidl
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...... hiện toàn bộ

D. Pedersen, K. Riis, T.B. Pedersen
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.
