Abstract

The ability to modify the existing published web pages is what we are calling Renarration of the web. Such a mechanism is useful for improving accessibility and personalization of the content currently on the web. There are many techniques in place for enabling both Web Accessibility and Web Personalization. In this paper we propose a novel approach: an Aspects inspired design of renarration. Aspects have traditionally been applied to programming. Here we reinterpret concepts like Join Points, Point-cuts and Advices and apply them to web documents. To validate our approach, we designed a framework called Rennaration Studio that is built using microservices based architecture pattern and implemented using Python's flask platform. We demonstrate the feasibility of our proposal by renarrating different Aspects (text, language, phonetics) of two specific web documents.

Abstract

Researchers have supported the idea of gamification to enhance students' interest in activities like code reviews, change management, knowledge management, issue tracking, etc. which might otherwise be repetitive and monotonous. We performed an experimental study consisting of nearly 180+ participants to measure the impact of gamification on code review process using 5 different code review tools, including one gamified code review instance from our extensible architectural framework. We assess the impact of gamification based on the code smells and bugs identified in a gamified and non-gamified environment as per code inspection report. Further, measurement and comparison of the quantity and usefulness of code review comments was done using machine learning techniques.

Abstract

In India, a large number of engineering undergraduates are adopting eLearning as it provides access to best faculty and reduces concerns on inadequate physical infrastructure at colleges. Virtual Labs is a Government of India eLearning initiative containing simulation and remote triggered labs for engineering students. Virtual Labs developed over a period of 6 years is used by more than a million undergraduate students across nine engineering disciplines. The software used for developing these experiments requires substantial effort for maintenance due to deprecation, compatibility, etc. We propose a targeted crowdsourcing approach for maintenance of Virtual Labs with sustainable quality. The targeted crowdsourcing involves the large number of engineering students who are also the major stakeholders of these labs. Our quality enhancement using crowdsourcing approach was validated for 14 labs and …

Abstract

Large organizations have diverse product offerings to meet various business needs. To increase revenue, its common these days to offer software products as integrated product suite (s) rather than individual products. Creating and maintaining high quality software products within the integrated product suite requires rigorous product engineering methods. The sheer size of products and dependencies involved tend to raise unidentified defects that may become critical post product upgrades or after every release cycle. It is difficult to track such defects and its widespread across underlying sub-products. In this paper, we present a model based approach to study the defect dependency in large scale integrated software products to avoid surprise defects after product release. To validate the approach, we have applied it on some pilot projects in industry.

Abstract

Bug tracking tools are vital for managing bugs in any open source as well as proprietary commercial projects. Considering the significance of using an appropriate bug tracking tool, we assess the features offered by 31 open source bug tracking tools and their significance of usage in open source projects. We have categorized these tools into different classes based on their features. We have also conducted a developer survey by working with open source software practitioners to understand the effectiveness of these tools in their day-to-day software development. We also explored StackOverFlow-a developer Q & A forum to understand the developer experiences and challenges while using open source bug tracking tools. Our observations generated encouraging results that can used as a recommendation guide for open source software community to choose the best bug tracking tool based on their functional needs. Additionally, we have identified few features that are needed but not offered by most of these bug tracking tools.

Abstract

1Ontologies have emerged as a common way of representing knowledge. Recently, people with minimal domain background or ontology engineering are developing ontologies, leading to a corpus of informal and under-evaluated ontologies. Existing ontology evaluation approaches require rigorous application of formal methods and knowledge of domain experts that can be cumbersome or tedious. We propose a lightweight approach for evaluating sufficiency of ontologies based on Natural Language Processing techniques. The approach consists of verifying the extent of coverage of concepts and relationships of ontologies against words in domain corpus. As a case study, we applied our approach to evaluate sufficiency of ontology in two example domains - Education (Curriculum) and Security (Phishing). We show that our approach yields promising results, is less effort intensive and is comparable with existing evaluation methods.

Abstract

Software quality has always been an important criterion for assessing stability of a product. It is quite challenging for large-scale complex products, especially integrated products, to endure and withstand the competition after a new version release in its market domain. Unlike regular software, integrated software products require detailed exploration on the spread and impact of a defect to improve overall product quality. In this paper, we use heuristic approaches like generalized defect dependency approach, control flow graph based approach, and feature correlation based approach to study the widespread of defects in large software and suggest a metric called defect dependency metric to study the dependency of defects. We implemented the generalized defect dependency approach on an industry dataset and gathered noteworthy results. We provide a comparative a study of the heuristic approaches …

Abstract

Software engineering activities like code reviews, change management, knowledge management, issue tracking, etc. tend to be heavily process oriented. Gamification of such activities by composing the core activities with game design elements like badges and points can increase developers' interest in performing such activities. While there are various frameworks/applications that assist in gamification, extending the frameworks to add any/all desired game design elements has not been adequately addressed. In this paper, we propose an extensible architectural framework for gamification of software engineering activities where in the game design elements are modeled as services. We create an example instance of our framework by building a prototype for code review activity and note the challenges of designing such an extensible architectural framework. The example instance uses python's Flask micro …

Abstract

Adobe Flash is a popular platform frequently used for creation of advertisements, videos and interactive contents on web pages. However its utility is lost with the decreasing support of Flash players on some platforms, where open standards like HTML5 and JavaScript are widely supported. This paper describes a transformation process for converting Flash files into HTML5 and Javascript to give a human readable output. This will lend users the same resourcefulness of Flash in open standards without relying on the former.

Abstract

Financial services sector typically known as BFSI (Banking Financial Services and Insurance) invest substantial amount of their developmental and maintenance budget in Information Technology (IT). Client servicing, regulatory/compliance requirements, effective risk monitoring among others necessitate such expenditure. A large amount of time and IT expenditure in BFSI sector is spent in reengineering the legacy systems. Successful execution of these reengineering programs is critical to the firm as well as the financial markets and regulators. In this paper, we present a report of the study done on reengineering three legacy systems in BFSI sector. The focus of the paper is on challenges and issues faced, practices followed, actual data collected by Mercury Quality Center during reengineering of these systems. Our study uses key metrics, client feedback, usage of these systems, document, process repository
