科学信息系统的建设和研究 完整的计算机系统，以支持科学研究。 这 项目正在建立一个示范“电子社区系统”， 数字图书馆包含了一个社区的所有知识， 分子生物学家和一个软件环境来操作它 库，目前正在运行第一个版本 20个生物实验室。 目前正在合作进行几项研究， 调查建筑中的技术和社会学问题 电子社区。 一个“信息空间”是 用于支持统一透明检索的表示， 许多分布式数据源;它由统一的对象组成， 打包来自源的项目，并将它们互连以形成 关系图 在提供数据模型方面存在一些问题， 跨多种数据类型的一致性和网络缓存问题， 提供跨广域网的交互的透明性。 在支持方面也存在信息检索问题 从自动生成的 表示，其中包括特定领域的词库。 最后，还有社会学问题， 社区的模式随着重大的电子 支持.

Science information systems is the construction and study of complete computer systems to support scientific research. This project is building a model "electronic community system", a digital library containing all the knowledge of a community of molecular biologists and a software environment to manipulate this library across the NSFNET, with the first release currently running in 20 biology laboratories. Several studies are being pursued in collaboration to investigate technology and sociology issues in constructing electronic communities. An "information space" is the representation used to support uniform transparent retrieval from many distributed data sources; it consists of uniform objects which package items from the sources and interconnect them to form a relationship graph. There are data model issues in providing uniformity across multiple data types and network caching issues in providing transparency of interaction across wide-area networks. There are also information retrieval issues in supporting semantic-based retrieval from an automatically generated representation which includes a domain-specific thesaurus. Finally, there are sociological issues in how the communication patterns of the community change with significant electronic support.
