Bug report is becoming a main approach to improve and perfect a complicated piece of software, but analyzing the bug report is a tedious and time-consuming job, especially when the number of bug reports is huge and many duplicate reports are mixed within the incoming bug reports. In this paper, we present a framework to automatically triage and detect the duplicate bug reports by keywords extraction...
Active replication is a common approach to handle failures in distributed systems, including Event Stream Processing (ESP) systems. However, one weakness of conventional active replication is that replicas, being equal and in the same state, are susceptible to common-mode crashes due to software bugs. We propose a new approach to active replication that assumes a failure model stronger than fail-stop...
Fault localization is one of the most expensive activities of program debugging, which is why the recent years have witnessed the development of many different fault localization techniques. This paper proposes a grouping-based strategy that can be applied to various techniques in order to boost their fault localization effectiveness. The applicability of the strategy is assessed over - Tarantula...
