TLDR
Good on-line help systems are of crucial importance for the computer systems of the future because increased functionality (required by the many different tasks which a user wants to do) will lead to an increased complexity.Abstract:
Good on-line help systems are of crucial importance for the computer systems of the future. An increased functionality (required by the many different tasks which a user wants to do) will lead to an increased complexity. Empirical investigations have shown that on the average only 40% of the functionality of complex computer systems are used. Passive help systems (which require that the user requests help explicitly from the system) are of little use if the user does not know the existence of a system feature. Active help systems should guide and advise an user similar to a knowledgeable colleague or assistant.read more

Knowledge-based help systems
TL;DR: The need for help systems as an essential part of human-computer communication is demonstrated and it is illustrated that passive and active help systems have to be constructed as knowledge-based systems.
Knowledge-based assistance for accessing large, poorly structured information spaces
TL;DR: A conceptual framework is developed that shows the need for a flexible organization of information access interfaces, personalized structure to deal with vocabulary mismatches and individual information needs, and semi-autonomous agents that assist in creating this personalized structure and an operational system (scINFOSCOPE) instantiate this framework allowing for the exploration and evaluation of the approach in realistic working environments.

The Importance of Models in Making Complex Systems Comprehensible
TL;DR: In this research, high functionality computer systems serve as prototypical examples for complex systems and are used to instantiate the framework of cooperative problem solving in joint human-computer systems.

Enhancing incremental learning processes with knowledge-based systems
TL;DR: In the past computer systems limited the user to modes of communication that made the machine’s job easier, but now, as computer cycles become plentiful, the focus can shift to the users and how to make it easier, more productive, and less frustrating for them to cope with complex systems.

Some observations on mental models
TL;DR: For instance, the authors argues that people's views of the world, of themselves, of their own capabilities, and of the tasks that they are asked to perform, or topics they are being asked to learn, depend heavily on the conceptualizations that they bring to the task.

Building and exploiting user models
TL;DR: Experiments with the Grundy system show that despite the fact that stereotypes are inherently imperfect, their use does contibute significantly to the system's ability to build useful models of its users.

Providing help and advice in task oriented systems
TL;DR: This work focuses on three general themes: (1) Help systems should be active rather than passive; (J) help systems should contain explicit models of the user, the task and the system utility being used and (3) the help system shoulJ engage in an interactive dialogue with the user in order to identify the information he really needs.

Talking to UNIX in English: An Overview of an On-Line UNIX Consultant
TL;DR: The goal of the Unix Consultant is to provide a natural language help facility that allows new users to learn operating system conventions in a relatively painless way as mentioned in this paper, which is not meant to be a substitute for a good operating system command interpreter, but rather, an additional tool at the disposal of the new user, to be used in conjunction with other operating system components.
