Roberts, Roger – 1969
HELP--a question-answering system--enables a user, sitting at the console of a time-shared computer, to obtain information on questions typed in. This information might concern the operating system itself, the format of commands to the user interface executive program, the use of a selected subsystem, or an area totally separate from the computer.…

Jackson, David M. – 1969
The idea of pseudo-classification based on external relevance was introduced and compared with the usual classifications using associative techniques. A general model for an information retrieval system using term classification was described. A set of operators for adjusting pseudo-classifications and preventing their deterioration was derived…
