We examine the problem of identifying, measuring and evaluating communities in blogs. In our approach, we use sense of community (McMillan and Chavis, 1986) and centrality measures derived from social network analysis. We then describe a method for identifying communities in blogs using both sense of community measurement and Social Network Analysis (SNA). We apply this framework to a blog on C...

Despite the longstanding nature of social network theory and its application to research on communication technologies, few IS studies employ social network analysis (SNA) concepts; the few that do are by organizational communication scholars. A recent stream of work by IS scholars is to apply SNA to study research collaboration – although this has mostly focused on individual IS conferences. W...

A Cloud-Based Design and Manufacturing (CBDM) System refers to an information and communication technology (ICT) system that facilitates design and manufacturing knowledge sharing between actors (e.g., CBDM service providers and consumers) in the distributed and collaborative socio-technical network. The aim of this study is to address the challenge of information sharing and technical communic...

This paper reports student interaction patterns and self-reported results of using Twitter microblogging environment. The study employs longitudinal probabilistic social network analysis (SNA) to identify the patterns and trends of network dynamics. It is building on earlier works that explore associations of student achievement records with the observed network measures. It integrates gender a...

Knowing patterns of relationship in covert (illegal) networks is very useful for law enforcement agencies and intelligence analysts to investigate collaborations among criminals. Previous studies in network analysis have mostly dealt with overt (legal) networks with transparent structures. Unlike conventional data mining that extracts patterns based on individual data objects, network structure...

The open source development community consists of both paid and volunteer developers as well as new and experienced users. Previous work has applied social network analysis (SNA) to open source communities and has demonstrated value in expertise discovery and triaging. One problem with applying SNA directly to the data of the entire project lifetime is that the impact of local activities will b...

In many organisations, conservation of specialised expertise is picked out as a central theme only after experienced members have already left. The paper presents the SELaKT method, a method for Sustainable Expert Localisation and Knowledge T ransfer based on social network analysis (SNA). It has been developed during a project co-operation between the Department of Information Science at the I...
