Title

Effect of grading schemes on outcomes in query writing experiments

Abstract

Findings of experiments comparing query languages are difficult to combine because the experiments have used different settings and procedures. Query accuracy, which has been determined using many different grading schemes, is the most important measure of user performance. Checks different schemes for possible effects on hypothesis rejection. Applies these grading schemes to 2 sets of queries from 2 different experiments. Examines the outcomes to identify any effect resulting from the grading schemes. Results show that the experimental outcomes are robust and immune to the grading schemes
