On‐line Information Retrieval: a Method of Query Formulation using a Video Terminal

Abstract

This paper discusses some particularly desirable features of the user‐computer dialogue involved in query formulation in an on‐line information retrieval system. The methods used in the Culham RIOT II system, designed to give on‐line access to a data base of 25, 000–50, 000 references, are described. To facilitate query formulation a matrix technique is employed and the most recent titles may be displayed while the query statement is under construction and before a full search is requested.

Interactive query formulation

“…QF is a key component of the information access process (Bates, 1986; Belkin, Cool, Croft, & Callan, 1993; Blair & Maron, 1985; Hall, Negus, & Dancy, 1972; Kuhlthau, 1991; Marchionini, 1995; Oddy, 1977). It is also very hard (Beghtol, 1986; Belkin, Oddy, & Brooks, 1991, 1982; Swanson, 1960; Taylor, 1968; ter Hofstede, Proper, & van der Weide, 1996).…”
