Plan Realization for Complex Command Interaction in the UNIX Help Domain

Abstract

Abstract. Yucca-* is a consultation system which is designed to provide the UNIX user, through a friendly interface, with detailed expert advice on the use of the UNIX command language. One of the principal design goals of this system is the ability to provide correct responses to technically complex queries whose solution may involve the interconnection of several commands, each with multiple options. The realization of such a goal requires two things. First, representation of dynamic knowledge about command behavior at a sufficient level of detail to support solution of the query is needed. Second, a planning mechanism capable of interconnecting such knowledge into a cohesive solution must be provided. This paper first develops the command dynamics representation techniques employed in Yucca-*. It then examines in detail the plan generation mechanism which is used to solve complex dynamic queries. Particular emphasis is placed upon those aspects of the problem which are unique to this particular domain.

Artificial Intelligence and User Experience in reciprocity: Contributions and state of the art

“…Various techniques and algorithms, such as rule-based systems, decision trees, and reinforcement learning, are employed to implement plan generation in these systems. For example, in [125], to achieve the design target of responding accurately to complex users' queries that involve the interconnection of multiple commands with various options, the system requires a detailed representation of dynamic knowledge about command behaviour and a planning mechanism that can integrate the knowledge into a cohesive solution.…”
