项目摘要

In recent years, networked workstations became ubiquitous because of the downsizing of computers. Such networked computers make it possible to realize novel computer-supported cooperative work (CSCW) systems, which provide new ways of collaborative work. The objectives of this research project include the realization of advanced CSCW systems using well-established technologies of databases. We performed the research in the following three directions.1) Conventional CSCW systems utilize video facilities. We utilize non-video facilities as well as video-based facilities.2) Simulation of the real world would be a useful way to realize a CSCW system. We not only use real world concepts and metaphors but also explore the possibilities of realizing such collaborative environments that allow us to do the things which we cannot do in the real world.3) Database functions including the ones allowing for reuse of information should be effectively utilized.Our major results include :1) We introduced concepts such as an object deputy model, a collaborative environment model and action view mechanisms based on the concept of database views.2) In order to manage interference problem in the sharing of hypermedia documents, concepts such as environment awareness and observability and controllability of users and tasks are introduced.3) To realize advanced mechanisms of collaborative work, we extended certain functions of active databases and workflow representations. In particular, privacy issues of active mechanisms, dynamic changes of CSCW environments, extension of IDEF0 model, which is one of the major methods to represent workflows are discussed4) We developed a prototype of hypermedia system having environment awareness mechanisms and personalization facilities.5) We discussed applications to 3D collaborative environments and collaborative retrieval of WWW pages and prototyped specific functions.

近年来，由于计算机的缩小尺寸，网络工作站变得无处不在。这样的网络计算机使实现新颖的计算机支持合作工作（CSCW）系统成为可能，从而提供了新的协作方式。该研究项目的目标包括使用良好的数据库技术实现高级CSCW系统。我们在以下三个方向上进行了研究。1）常规CSCW系统利用视频设施。我们利用非视频设施以及基于视频的设施。2）现实世界的仿真将是实现CSCW系统的有用方法。 We not only use real world concepts and metaphors but also explore the possibilities of realizing such collaborative environments that allow us to do the things which we cannot do in the real world.3) Database functions including the ones allowing for reuse of information should be effectively utilized.Our major results include :1) We introduced concepts such as an object deputy model, a collaborative environment model and action view mechanisms based on the concept of database views.2) In order to在共享HyperMedia文档的共享中管理干扰问题，介绍了环境意识以及用户和任务的可观察性和可控性等概念。3）为实现协作工作的高级机制，我们扩展了活动数据库和工作流程表示的某些功能。 In particular, privacy issues of active mechanisms, dynamic changes of CSCW environments, extension of IDEF0 model, which is one of the major methods to represent workflows are discussed4) We developed a prototype of hypermedia system having environment awareness mechanisms and personalization facilities.5) We discussed applications to 3D collaborative environments and collaborative retrieval of WWW pages and prototyped specific functions.
