TAILIEUCHUNG - Báo cáo khoa học: "Multiple Underlying Systems: Translating User Requests into Programs to Produce Answers"

A user may typically need to combine the strengths of more than one system in order to perform a task. In this paper, we describe a component of the Janus natural language interface that translates intensional logic expressions representing the meaning of a request into executable code for each application program, chooses which combination of application systems to use, and designs the transfer of data among them in order to provide an answer. | Multiple Underlying Systems Translating User Requests into Programs to Produce Answers Robert J. Bobrow Philip Resnik Ralph M. Weischedel BBN Systems and Technologies Corporation 10 Moulton Street Cambridge MA 02138 ABSTRACT A user may typically need to combine the strengths of more titan one system in order to perform a task. In this paper we describe a component of the Janus natural language interface that translates inten-sional logic expressions representing the meaning of a request into executable code for each application program chooses which combination of application systems to use and designs the transfer of data among them in order to provide an answer. The complete Janus natural language system has been ported to two large command and control decision support aids. 1. Introduction The norm in the next generation of user environments will be distributed networked applications. Many problems will be solvable only by use of a combination of applications. If natural language technology is to be applicable in such environments we must continue to enable the user to talk to computers about his her problem not about which application s to use. Most current natural language NL systems whether accepting spoken or typed input are designed to interface to a single homogeneous underlying system they have a component geared to producing code for that single class of application systems such as a single relational database 12 . Providing an English interface to the user s data base a separate English interface to the same user s planning system and a third interface to a simulation package for instance will neither be attractive nor cost-effective. By contrast a seam ess mufti-modal natural language interface will make use of a heterogeneous environment feasible and if done well transparent this can be accomplished by enabling the user to state information needs without specifying how to decompose those needs into a program calling the various underlying systems .
