A “Human-in-the-loop” approach for resolving complex software anomalies

Automated static analysis tools are widely used in identifying software anomalies, such as memory leak, unsafe thread synchronization and malicious behaviors in smartphone applications. Such anomaly-prone scenarios can be bifurcated into: “ordinary” (analysis requires relatively simple automation) and “complex” (analysis poses extraordinary automation challenges). While automated static analysis tools can resolve ordinary scenarios with high accuracy, automating the analysis of complex scenarios can be very challenging and, at times, infeasible. Even when feasible the cost for full automation can be exorbitant: either in implementing the automation or in sifting through the large number of erroneous results manually. Instead, we appeal for a “Human-in-the-loop” approach called “Amplified Reasoning Technique” (ART). While some of the existing approaches do involve human in the analysis process, the roles played by man and machine are mainly segregated. Whereas, ART puts man and machine in a “loop” in an interactive and visualization-based fashion. This paper makes an attempt to convince its readers to make their analysis of software anomalies ART-based by presenting real-world case studies of complex anomalies and how an ART based approach can be very effective in resolving them. The case studies highlight the desired characteristics of an ART based tool and the type of role it plays in amplifying human intelligence.
