Rule-Directed Interactive Transaction Agents: An Approach to Knowledge Acquisition.
Waterman, D. A.
This report describes the development of computer programs called user agents, which, through interaction with users, can either learn new facts and store them in a data base or learn new procedures for data manipulation and represent them as programs. These programs are written in RITA, the Rule-directed Interactive Transaction Agent system, and are organized as sets of IF-THEN rules or "production systems." The programs are able to act as "personal computer agents" to perform a variety of tasks. Four types of RITA agents are (1) an exemplary programing agent that watches a user perform an arbitrary series of operations on the computer and then writes a program (a new RITA agent) to perform the same task; (2) a self-modifying agent that performs ARPAnet file-transfer tasks for the user, modifying itself so that each subsequent time it performs the task, it can do so with less help from the user; (3) a tutoring agent that watches an expert demonstrate the use of an interactive computer language or local operating system and then creates a teaching agent that can help naive users become familiar with the language or system demonstrated by the expert; and (4) a reactive-message creating agent that elicits text from a user (the sender) and uses it to create a new RITA agent which is a reactive message; the reactive message is then sent to some other user (the recipient), who interacts with it; and during the course of the interaction, a record of the recipient's responses is sent back to the sender.
