摘要
本文以任务为驱动,根据任务关联的信息需求研究了如何从异构数据源中抽取合适的数据并进行再加工,根据任务所关注的焦点分析其所包含的各种要素,以及这些要素之间的内在和外部联系,并从任务、时间、地理、单位等不同的视角研究对数据进行多维组织的构成和方法。以精确信息服务为目标,提出了基于需求的可视化信息展现框架,分析并实现了信息导航区、细节展现功能区、媒体索引功能区、卡片功能区以及相关链接区的展现模式和关键技术。通过多维数据组织和模版技术,初步解决了用户展现需求与数据资源建设不同步的问题,实现了精确信息服务与数据资源库的分离。
Driven by missions, the paper studies how to extract proper data from the heterogeneous data source for reprocessing according to the information demand associated with the missions. And according to the focus specific to the missions,the paper analyses the related factors and both the internal and external associations between them, and investigates the structures and methods of realizing multidimensional organization on the data from different angles such as mission, time,geography and unit. With the precise information service as the objective, the paper proposes a visualized information exhibition framework based on demands, analyses and implements the information navigation area, detail exhibition functional area, media index function area, card function area, and correlative link area. By multidimensional data organization and the template technique, we primarily solve the problem of asychronization between user exhibition repuirements and data resource construction, thus separate the precise information service from the data resource repository. Practice shows the idea has a certain value both in theory and application.
