面向科学数据的搜索引擎voovle

voovle: A Scientific Data-Oriented Search Engine

科学研究产生的科学数据资源日益激增,仅在中国科学院科学数据库"十一五"信息化建设中整合全院科学数据库形成的共享数据量就多达148TB。为了充分发挥这些共享科学数据的价值,结合科学数据的专业特点,提供一套跨库统一检索、不同领域科学资源关联及发现的搜索工具,具有重要的实用价值。本文阐述面向科学数据搜索引擎voovle提出的背景、面临的问题,重点介绍了voovle的功能与实现,详述元数据模型等几项关键技术。最后通过案例介绍了voovle目前的应用情况、存在的不足以及下一步的发展方向等。

With the development of scientific research, scientific data has been exploding increasingly. In the days when scientific research activities and data consuming across multiple disciplines become more and more common, it is necessary to provide a unified and cross-database search engine for open data and rnetadata. In the first part of this paper, the authors show the background and the possible problems of the scientific data-oriented search engine. Then, this paper presents voovle as a scientific data-oriented search engine and focuses on the functions and implementation. In section three, some key technologies of voovle are discussed in detail. Finally, current application situation, existing shortcomings and the future direction of voovle are briefly described.
