Community of Inquiry (CoI) model is a framework with socio-constructivist roots, which describes an online learning community on three interdependent components: cognitive presence, social presence and teaching presence. Content analysis is widely used to examine transcripts of computer mediated conversations between students in a community of inquiry. However, there are no dedicated support tools...
Crowdsourcing of mobile content through games is becoming a major way of populating information-rich online environments. A current research gap is that actual usage patterns of crowdsourcing games has been inadequately investigated. We address this gap by comparing content creation patterns in a game for crowdsourcing mobile content against a non-game version. Results show distinct differences in...
Collective intelligence refers to the intelligence that emerges from local interactions among individual people. In the last few decades, Web 2.0 technologies have enabled new forms of collective intelligence that allow massive numbers of loosely organized individuals to interact and create high quality intellectual artifacts. In computer and information science disciplines, automated computational...
The Web is an important resource for health information. Pew's Internet and American Life Project found 62% of adult Web users looking for health-related information on health social networks. However, the National Survey on Identity and Privacy in Social Media by The Ponemon Institute reported that about 56% of adult users were anxious about the privacy of their personal information on social networks...
Based on existing researches about interaction analysis, this paper designs an interaction analysis coding system to study the level of knowledge construction in web-based interaction. Methods of content analysis and social network analysis are used to analyze the interaction content of a web class on Moodle, which provides a web-based learning platform for a national level excellent course named...
Asynchronous discussion forum can provide a platform for online learners to communicate with one another easily, without the constraint of place and time. This study explores the analysis process of online asynchronous discussion. We focus upon content analysis and social network analysis, which is the technique often used to measure online discussion in formal educational settings. In addition, Soller's...
In order to solve the problem that we can only collect data from one single data source at some fixed time after mining the keywords in a rather superficial level, and to take full use of the information returned by search engines to construct the social relationship network based on the semantic link of the searched subject, we do the regular research by using the ROST Content Mining System which...
Asynchronous Discussion Forum (ADF) is now regularly as a component of Computer Mediated Communication (CMC) and take a central place in Computer Supported Collaborative Learning (CSCL). However, it is apparent that the field of CMC or CSCL lacks established methodologies to analyze it. This paper discusses the problem overview and offers a solution concept to integrate between Content Analysis (CA)...
Social networks have recently attracted much attention for their importance to the semantic Web. Several methods exist to extract social networks for people from the Web based on co-occurrence information. This paper proposed a content analysis based method for automatic obtaining social networks among various entities from Chinese event-based news stories. First, the input articles are annotated...
Web forums provide platforms for any Internet users around the world to communicate with each other and express their opinions. In many of the discussions in Web forums, it involves issues related to terrorism and crime. Some participants are even using the platform to propagandize their ideology or recruit members to commit crime. In this work, we propose a Web forum analysis system to analyze the...
