Computer-Support for Collaborative Writing

这个项目的目标是继续开发一个“正在准备的工作”(PREP)编辑，以研究协作写作关系。拟议的工作建立在先前工作的基础上，这些工作导致设计了一个原型编辑器，该原型编辑器支持社会交互的一些重要认知需求，例如(1)承认个人对协作的贡献和(2)检测从一个版本到另一个版本的变化。虽然该项目继续解决支持共同工作的作家的认知需求的进一步问题，但该项目也开始努力支持写作群体的社会需求，如灵活分享部分产品和管理部分写作任务的需求。例如，为了支持部分产品的灵活共享，该项目定义了一组参数，允许用户控制他们交换的内容(字符、段落、列、文档)、何时交换(根据请求自动交换)以及交换的速度。这方面的工作为计算机科学做出了理论和实践上的贡献。支持协作作者的认知需求的工作导致在文本和图形编辑中嵌入更通用、连贯和一致的注释模型。支持协作写作小组的社会需求的工作导致了协作文档的新协议的开发，这些协议被建模为分布式的、可断开连接的数据库。

The goal of this project is to continue development of a "work in preparation" (PREP) editor to study collaborative writing relationships. The proposed work builds on previous work that resulted in design of a prototype editor that supports some important cognitive needs of social Interaction such as (1) the recognition of individual contributions to a collaboration and (2) the detection of change from one version to another. While the project continues to address further issues in supporting the cognitive needs of writers working together, the project also begins to work on supporting the social needs of writing groups,needs such as flexible sharing of partial products and managing parts of the writing task. For example, to support flexible sharing of partial products, the project defines a set of parameters that will allow users to control what they exchange (character, paragraph, column, document), when they exchange it (automatically, upon request) and the speed of exchange. The work on this front makes a theoretical and practical contribution to computer science. The work on supporting the cognitive needs of collaborative writers leads to embedding in text and graphic editors more general, coherent an consistent models for annotations. The work on supporting the social needs of collaborative writings groups leads to the development of new protocols for collaborative documents, modeled as distributed, disconnectable databases.
