Presented a paper on Collaborative Information Seeking at the 2016 International Conference on Collaboration Technologies and Systems (CTS)

Paper Title:
A Research Plan to Study Impact of a Collaborative Web Search Tool on Novice's Query Behavior

In the past decade, research efforts dedicated to studying the process of collaborative web search have been on the rise. Yet, limited number of studies have examined the impact of collaborative information search process on novice’s query behaviors. Studying and analyzing factors that influence web search behaviors, specifically users’ patterns of queries when using collaborative search systems can help with making query suggestions for group users. Improvements in user query behaviors and system query suggestions help in reducing search time and increasing query success rates for novices. In this paper, we present an empirical study plan designed to investigate the influence of collaboration between experts and novices as well as use of a collaborative web search tool on novice’s query behavior. In this research-in-progress study, we intend to use SearchTeam as our collaborative search tool. The results of this study are expected to provide information that could help collaborative web search tool designers to find ways to improve the query suggestions feature for group users. Additionally, this study will test the hypothesis that – having domain experts working with non-experts using collaborative search systems would immensely increase the query success rates for non-expert users, and help them learn querying strategies over the course of time. If the above hypothesis is proven, then use of collaborative web search tools during training of interns would be highly recommended.

Presented a Paper on IT Standards and Participated in Panel Discussions on Big Data Analytics and Service Computing at the 2015 Workshop on e-Business (WeB)

Paper Title:
Investigating IT Standardization Process through the lens of Theory of Communicative Action

Developing standards is a social practice wherein experts engage in discussions to evaluate design solutions. In this paper, we analyze processes followed to develop SOAP standard from the theory of communicative action
perspective, which argues that individuals engaged in social discourse would exhibit five possible actions: instrumental, strategic, normatively regulated, dramaturgical, and communicative. Our findings reveal that participants in standardization processes engage in communicative action most frequently with aim of reaching mutual understanding and consensus, engage in strategic action when influencing others towards their intended goals, engage in instrumental action when taking responsibility for solving technical issues, engage in dramaturgical action when expressing their opinions, and engage in normatively regulated action when performing roles they assumed. Our analysis indicates that 60% of activities performed are consensus oriented whereas the rest are success oriented. This paper provides empirical evidence for Habermasian view of social actions occurring in the standardization process setting.
