Shared Software Database

该项目的目标是开发技术， 使用广域网搜索和共享软件。 这 将使软件重用超越库;一个程序编写 对于单个项目，可能不会直接使用，而是用作 其他项目中类似程序的模板。 首席研究员正在进行新的研究， 索引和查询软件数据库。 索引信息必须 自动生成，不需要程序额外的努力 造物主 最初，他正在增强现有的CASE工具，以生成 这样的索引信息。 后续研究将整合其他 软件分类的机制。 该项目的另一部分是 为了开发用于广泛分布的分布式查询机制， 自主的软件数据库。 这将包括以下功能 自动取消生成太多结果的查询。 一个帮助用户指定和细化查询的界面正在开发中。 设计了 虽然这项工作的重点是共享计算机软件， 开发的技术可以证明在分享其他 信息，例如来自科学实验的数据或有限的 （未发表的）研究。

The objective of this project is to develop techniques for searching for and sharing software using wide-area networks. This will enable software reuse to go beyond libraries; a program written for a single project may not be used directly, but instead be used as a template for similar programs in other projects. The principal investigator is conducting new research into indexing and querying software databases. Indexing information must be generated automatically, with no extra effort by the program creator. Initially he is augmenting an existing CASE tool to generate such indexing information. Later research will integrate other mechanisms for categorizing software. Another part of the project is to develop a distributed query mechanism for widely distributed, autonomous, software databases. This will incorporate features such as automatically canceling queries which generate too many results. An interface which helps user specify and refine queries is being designed. Although the focus of this work is on sharing computer software, the techniques developed could prove useful in sharing other information, such as data from scientific experiments or limited interest (and therefore unpublished) studies.
