Increased connectivity and the use of the internet have exposed the subversion in front of the organizations, there for there is a need to use of intrusion detection system to protect information system and communication network from malicious attacks and unauthorized access. An intrusion detection system (IDS) is a security system that monitors computer(More)
Events give important information about the behavior of a system in a summarized form. In the past, events have played an important role in breaking the functional requirements of the system in the “Event Partitioning Approach”. Our previous work has shown that Events can be a starting point in Object-Oriented Analysis of requirements. Every(More)
Bug reports of open source software systems are increasing exponentially. One reason for growing bug reports is that bug reporters do not browse the bug repository before submitting a bug report. There may be some similar bugs already reported: one, which are exactly similar or duplicate and other, which are semantically similar means they may belong to the(More)
—Ranking thousands of web documents so that they are matched in response to a user query is really a challenging task. For this purpose, search engines use different ranking mechanisms on apparently related resultant web documents to decide the order in which documents should be displayed. Existing ranking mechanisms decide on the order of a web page based(More)
This paper presents, a domain independent tool, developed in JAVA that automates the process of extraction, analysis and classification of events from textual requirements, expressed in English as a Natural Language. A study on various existing event extraction tools shows that they are either domain specific or take events as actions that occur at a(More)
—Safety critical systems, real time systems, and event-based systems have a complex set of events and their own interdependency, which makes them difficult to test ma Safety critic Safety critical systems, real time systems, and event-based systems have a complex set of events and their own interdependency, which makes them difficult to test manually.

Problem statement: Event-based systems have importance in many application domains ranging from real time monitoring systems in production, logistics, medical devices and networking to complex event processing in finance and security. The increasing popularity of Event-based systems has opened new challenging issues for them. One such issue is to carry out(More)
Most open source projects provide a defect tracking system, where users, developers, testers can directly report the problems. The fields provided in the bug report help triager and debugger to understand the problem better. They also help in other tasks like accurate assessment of priority and severity of bugs, identification of appropriate developer to(More)
