This paper reports an empirical user study of an active reuse repository system. Instead of waiting passively for software developers to initiate the component location process with a well-defined reuse query, active reuse repository systems infer reuse queries from syntactic and semantic cues present in partially constructed programs in development environments, and proactively deliver components that match the inferred reuse queries. The reported empirical user study of an implemented active

... euse repository system called CodeBroker shows that active repository systems promote reuse by motivating and enabling software developers to reuse components whose existence is not anticipated, and reducing the cost of reuse through the automation of the component location process.
