Designing and testing an interactive Ranked retrieval system for professional searchers
E. Michael Keen · Journal of Information Science · 1994
Reports three explorations of Ranked system design. Two tests used a Cystic Fibrosis test collection with 100 queries. Experiment 1 compared a Boolean with a Ranked interactive system using a subject-qualified trained searcher, and reporting Recall and Precision results. Experiment 2 compared fifteen different Ranked match algo rithms in a batch mode using two test collections, and included some new proximate pairs and term weighting approaches. Experiment 3 is a design plan for an interactive Ranked prototype offering mid-search algorithm choices plus other manual search devices (such as obligatory and unwanted terms), as influenced by thinking-aloud comments from experiment 1.
