User-model-driven generation of instructions.

There has been a great deal of research on specific issues of user modeling (e.g., generation of explanations (Paris 88), implicit knowledge acquisition (Kass, Finin 87), exploitation of user feedback to compensate for the unreliability of user models (Moore, Paris 92), but to our knowledge no work has been done on how to integrate this work into a single system. In TECHDOC-I we combine a number of ideas and work from various areas in a single system, add some unique features (e.g., application of a double-stereotype mechanism to plan representation), and apply them to a new domain (instructions for car maintenance). TECHDOC-I provides support to a user in the area of car maintenance. All maintenance activities are represented by plans, which consist of plan steps. The dialogue between user and system is based on these plans. A user model ensures that the system adapts the content of the output to the user. The commands and explanations are given in natural language that is generated by a (multilingual) text generator. [ABSTRACT FROM AUTHOR]
