A parser for on-line search system evaluation

Abstract

This paper describes a computer program which converts the text of user input and system responses from an on-line search system into fixed format records which describe the interaction. It also outlines the syntax of the query language and the format of the output record produced by the parser. The study discusses problems in constructing the parser, the logic of the parser and its performance characterestics, as well as recommendations for improving the process of logging on-line searches.
