Case and Model Driven Dynamic Template Linking

摘要

This report summarizes a tool created under the DARPA Active Templates (AcT) program that allows users to define templates, actively use (and modify) those templates for problem solving, and supports the reuse of templates based on case-based reasoning. The goal of the AcT program was to develop and apply a spreadsheet-based planning metaphor to improve the Special Operations Forces mission-planning process. The tool, TRACKER Template Retrieval and Adaptation of Case Knowledge for Evaluation and Reuse, stores and indexes template patterns and employs efficient search and retrieval mechanisms to support the fast retrieval and reuse of templates. TRACKER utilizes techniques from case-based and model-based reasoning to decrease planning time and yield higher quality plans. A tool called the Browser was developed to store templates and support the interchange of TRACKER templates with other AcT systems. During the project the TRACKER tool was used to support a number of domains. A version of the tool called Digital Command and Control System (DC2S) was developed to support Special Operations crisis action planning. TRACKER was also modified for application to numerous domains including travel planning, collaborative planning, workflow management, diplomatic clearance requirements for foreign country overflights, and incident response planning after nuclear, biological or chemical attacks.
