UNIVERSITY OF SOUTHERN CALIFORNIA MARINA DEL REY INFORMATION SCIENCES INST
The military message service proposed by ISIs Information Automation project is designed to provide full documentation, help, and error-reporting facilities on-line. The Tutor serves these functions by accessing a documentation or Help data base which contains multilevel descriptions for every semantic entity used in the interface between the service and the user. These descriptions are expandable with respect to the amount and type of information presented, as well as with respect to the users level of proficiency and experience, as indicated by a User Profile. The Tutor also provides a facility for on-line computer-aided instruction. It can be invoked explicitly by the users request for help, or by the Command Language Processor and User Monitor in response to unrecognized commands, inefficient operation, or error conditions.
