Beyond the backchannel: Leveraging Twitter to enact learning processes

Conferences provide opportunities for participants to learn with each other through social discovery, interaction and knowledge development. Increasingly, Twitter provides an online backchannel surrounding conference activities. This backchannel both augments in-person interactions, and provides a means for people not in attendance to follow and contribute to the dialogue. Thus, Twitter backchannels provide learning opportunities both for those in attendance, and for others in the wider Twitter-verse. Given that conferences are a forum in which interactive learning takes place, how might Twitter participation at conferences facilitate learning? This session intends to initiate a collaborative dialogue around this inquiry using Twitter as a catalyst, complementing the existing iConference Twitter backchannel. This exploration will focus on content and network analysis methods, discussions on learning networks, and ideation around Twitter as a learning tool. We invite participation both through attendance in the introductory and concluding sessions, as well as via Twitter throughout the conference.ye

Creative professional users musical relevance criteria

Although known item searching for music can be dealt with by searching metadata using existing text search techniques, human subjectivity and variability within the music itself make it very difficult to search for unknown items. This paper examines these problems within the context of text retrieval and music information retrieval. The focus is on ascertaining a relationship between music relevance criteria and those relating to relevance judgements in text retrieval. A data-rich collection of relevance judgements by creative professionals searching for unknown musical items to accompany moving images using real world queries is analysed. The participants in our observations are found to take a socio-cognitive approach and use a range of content and context based criteria. These criteria correlate strongly with those arising from previous text retrieval studies despite the many differences between music and text in their actual content

Experience of developing Twitter-based communities of practice in higher education

This article presents the results of a case study of the use of a microblogging tool by a university academic to increase their knowledge and experience of social media for educational purposes. The academic had the role of digital steward in a university and attempted to use microblogging (Twitter) to increase professional contacts within the framework of a community of practice. Several types of data were collected and analysed. These included the structure of the network arising from the links formed with others by microblogging, the similarity of stated interests between the academic and others in the network, and the contents of postings such as their external references. It was found that a personal network had been established, with some of the characteristics of a community of practice. The activity demonstrated the utility of social media in supporting the professional development of academic staff using technology

How social media can afford engagement processes

The increasing popularity of social media has led many organizations to find new ways of customer engagement. This paper presents an initial pilot study to explore the affordance of social media in engagement processes. By applying the affordance theory and Porter’s process for engagement model, we used a case study approach to examine the case company’s Facebook and Twitter content to identify the engagement possibilities of social media. Our preliminary results show that social media opens a new channel for organisations to engage with their customers. We present a preliminary theoretical model to understand the how the functional affordances of social media are socialised in engagement processes, which ultimately gives rise to socialised affordances

Social features of online networks: the strength of intermediary ties in online social media

An increasing fraction of today social interactions occur using online social media as communication channels. Recent worldwide events, such as social movements in Spain or revolts in the Middle East, highlight their capacity to boost people coordination. Online networks display in general a rich internal structure where users can choose among different types and intensity of interactions. Despite of this, there are still open questions regarding the social value of online interactions. For example, the existence of users with millions of online friends sheds doubts on the relevance of these relations. In this work, we focus on Twitter, one of the most popular online social networks, and find that the network formed by the basic type of connections is organized in groups. The activity of the users conforms to the landscape determined by such groups. Furthermore, Twitter's distinction between different types of interactions allows us to establish a parallelism between online and offline social networks: personal interactions are more likely to occur on internal links to the groups (the weakness of strong ties), events transmitting new information go preferentially through links connecting different groups (the strength of weak ties) or even more through links connecting to users belonging to several groups that act as brokers (the strength of intermediary ties).Comment: 14 pages, 18 figure

How Digital Are the Digital Humanities? An Analysis of Two Scholarly Blogging Platforms

In this paper we compare two academic networking platforms, HASTAC and Hypotheses, to show the distinct ways in which they serve specific communities in the Digital Humanities (DH) in different national and disciplinary contexts. After providing background information on both platforms, we apply co-word analysis and topic modeling to show thematic similarities and differences between the two sites, focusing particularly on how they frame DH as a new paradigm in humanities research. We encounter a much higher ratio of posts using humanities-related terms compared to their digital counterparts, suggesting a one-way dependency of digital humanities-related terms on the corresponding unprefixed labels. The results also show that the terms digital archive, digital literacy, and digital pedagogy are relatively independent from the respective unprefixed terms, and that digital publishing, digital libraries, and digital media show considerable cross-pollination between the specialization and the general noun. The topic modeling reproduces these findings and reveals further differences between the two platforms. Our findings also indicate local differences in how the emerging field of DH is conceptualized and show dynamic topical shifts inside these respective contexts
