Twitter user profile information is very useful for various fields such as marketing, HRD, advertising, and personalization. Since user profile provided by Twitter is very limited, some latent attributes such as gender, age, work, or interest should be predicted. In this paper, we aim to predict those four latent attributes using her/his tweet and bio data by employing machine learning techniques...
A social role is a special position an individual possesses within a network, which indicates his or her behaviours, expectations, and responsibilities. Identifying the roles that individuals play in a social network has various direct applications, such as detecting influential members, trustworthy people, idea innovators, etc. Roles can also be used for further analyses of the network, e.g. community...
We present our novel community mining algorithm that uses only local information to accurately identify communities, outliers, and hubs in social networks. The main component of our algorithm is the T metric, which evaluates the relative quality of a community by considering the number of internal and external triads (3-node cliques) it contains. Furthermore we propose an intuitive statistical method...
Many real-world networks exhibit overlapping community structure in which vertices may belong to more than one community. It has been recently shown that community structure plays an import role in epidemic spreading. However, the effect of different vertices on epidemic behavior was still unclear. In this paper, we classify vertices into overlapping and non-overlapping ones, and investigate in detail...
Although now 20 years old, only recently has the concept of technical debt gained some momentum and credibility in the software engineering community. The goal of this fourth workshop on managing technical debt is to engage researchers and practitioners in exchanging ideas on viable research directions and on how to put the concept to actual use, beyond its usage as a rhetorical instrument to discuss...
In this paper, we introduce a novel touristic trip suggestion system to facilitate the traveling of mobile users in a given city. Given the current user location and his touristic destination, our system can suggest a shortest trip path that visits as many popular landmarks as possible. To this end, we collect geographical tagged photos from Flickr [1] and Panoramio [2] photo sharing websites. Then...
We examine digital social media ecosystems such as blogs and mailing lists from the perspective of communities of practice. We observe behaviors of agents and specify prevalent patterns of collaborations in digital media ecosystem.We describe several techniques important in patterns specification such as social network analysis and content analysis. The conceptualization of our observations was done...
Social media are more than just a buzzword or an interesting phenomenon to our teenagers, they are a way of life. Research shows that active participation on sites like Facebook, communicating via texting and chat programs, and creating blogs are everyday occurrences for a generation of students. Yet these same students do not consider the impact of these tools on their lives for good or ill. Furthermore,...
This study describes the design and implementation of an online intellectual community that targeted only the School of Information Systems and Technology (SISAT) at CGU, and the steps taken to foster active participation amongst community members. The artifact developed was an online community for the purpose of improving the sense of community amongst students, faculty, and alumni of SISAT by allowing...
