Social Media For Informal Science Learning In China: A Case Study, Ke Zhang, Fei Gao

Fei Gao

This article reports a case study on a popular informal science learning community via social media in China, named GuoKr (meaning “nutshell” in English). Data were collected through a variety of Chinese social media and social networking sites, web-based community portals, and discussion boards. Content analyses and data mining were conducted to investigate how GuoKr successfully attracted and engaged public in informal learning on scientific topics in particular. The study found three key characteristics that contributed to the success of such learning communities: (a) utilizing a variety of social media to empower participants with just-in-time, accidental learning opportunities; (b) daily …

Editorial: The Idio-Technopolis, Katina Michael

Professor Katina Michael

The rapid rise of social media has brought with it an emphasis on the distinct dimensions of the whole person. Social media recognises that the individual has a personal network of extensions- a home life, a work life, a social life, a study life, a hobbyist life, and much more- some of these identities even hidden from full view. Each of these online value networks are now accessible by big business, where opinion leaders and early adopters are easily distinguishable, and where brand commentary between consumers matters manifold more than any form of targeted advertising.

Semantic Geotagging: A Location-Based Hypermedia Approach To Creating Situational Awareness, Ray Bareiss, Martin Griss, Steven Rosenberg, Yu Zhang

Ray Bareiss

As emergency first responders and commanders increasingly use mobile phones, tablets, and social media to communicate, coordinate, and manage information during disasters, we see a need and opportunity to provide a mobile device-appropriate semantic layer to a geographically-based common operating picture. The challenge is to provide a simple, usable structure for a rapidly growing body of information to simplify the development of situational awareness in an unfolding disaster. We use a hyperlinked structure based on the ASK model to organize information in a readily accessible form. In this paper we describe our initial design and experience with an Android-based prototype, …

Using Textual Features To Predict Popular Content On Digg, Paul H. Miller

Paul H Miller

Over the past few years, collaborative rating sites, such as Netflix, Digg and Stumble, have become increasingly prevalent sites for users to find trending content. I used various data mining techniques to study Digg, a social news site, to examine the influence of content on popularity. What influence does content have on popularity, and what influence does content have on users’ decisions? Overwhelmingly, prior studies have consistently shown that predicting popularity based on content is difficult and maybe even inherently impossible. The same submission can have multiple outcomes and content neither determines popularity, nor individual user decisions. My results show …
