“…The creation of shared metadata on e-learning objects through social tagging is another promising aspect of collaborative content creation in e-learning environments (Dahl & Vossen, 2008;Limpens, Gandon & Buffa, 2008;Lux & Dosinger, 2007;Maier & Thalmann, 2008). Rather than relying on established top-down ontologies and directories, bottom-up 'folksonomies' support the learner by providing a cognitive tool for knowledge building and negotiation: to tag a learning object the learner needs to develop an understanding sufficient enough to be able to summarize it by a set of keywords.…”

“…Staley (2009) claims that Web 2.0 technologies "represent as important a historical phenomenon as the birth of bureaucracy" (p. 38) in that "they signal a participatory turn in our culture" (p. 39). Far from being a passing fad represented by Facebook, YouTube, Wikipedia, Twitter, or any other individual instantiation, Web 2.0 is an evolution in the social architecture and functionality of the Web (Limpens, Gandon, & Buffa, 2008) representing the potential of the individual-what Staley calls "wikinomics, a new form of social economy based on a truly participatory framework. About the future of the tertiary institution, he asks: "How will the logic of wikinomics affect [the] time-honored arrangement between teachers and students?"…”

PurposeThe paper introduces an enterprise-wide Web 2.0 learning support platform-SNAPdeveloped at Victoria University in Melbourne, Australia. Design/methodology/approachPointing to the evolution of the social web, the paper discusses the potential for the development of e-learning platforms that employ constructivist, connectivist, and participatory pedagogies and actively engage the student population. Social networking behaviours and peer-learning strategies, along with knowledge management through guided folksonomies, provide the backbone of a social systems approach to learning support. FindingsDevelopment of a cloud-based read-write enterprise platform can extend the responsiveness of the learning institution to its students and to future e-learning innovations. Originality/valueThe full potential of e-learning platforms for the development of learning communities of practice can now be increasingly realised. The SNAP Platform is a step in this direction.

“…Several other research works tried to tackle the limitations of folksonomies by bridging them with ontologies [5]. Passant and Laublet [6] have proposed a model (MOAT) and some tools to link tags with their different meanings which are expressed within documents (Wikipedia articles) or concepts instances available on the Semantic Web.…”

The advent of tagging and folksonomies for organizing shared resources on the social Web brought promising opportunities to help communities of users capture their knowledge. However, the lack of semantics, or the spelling variations between tags lowers the potentials for browsing and exploring these data. To overcome these limitations, we propose exploiting the interactions between the users and the systems to validate or correct semantic analysis automatically applied to the tags. This process is based upon our model of the assistance of folksonomies enrichment which supports conflictual points of view. Several strategies can then be applied to propose novel browsing facilities to users.

“…The lack of structure in folksonomies means that content retrieval tasks, such as searching, subscription and exploration, are limited (Begelman, Keller and Smadja, 2006;Limpens, Gandon and Buffa, 2008;Angeletou, Sabou and Motta, 2008;Lin and Davis, 2010). Acquiring latent hierarchical structures from folksonomies and creating tag hierarchies can be useful in improving content retrieval (Laniado, Eynard and Colombetti, 2007), and also other different tasks, such as building lightweight ontologies (Mika, 2007) and enriching knowledge bases (Zheng, Wu and Yu, 2008).…”

Content on the Web is huge and constantly growing, and building taxonomies for such content can help with navigation and organisation, but building taxonomies manually is costly and time-consuming. An alternative is to allow users to construct folksonomies: collective socialclassifications. Yet, folksonomies are inconsistent and their use for searching and browsing is limited.Approaches have been suggested for acquiring implicit hierarchical structures from folksonomies, however, but these approaches suffer from the 'popularity-generality' problem, in that popularity is assumed to be a proxy for generality, i.e. high-level taxonomic terms will occur more often than lowlevel ones. To tackle this problem, we propose in this paper an improved approach. It is based on the Heymann-Benz algorithm, and works by checking the taxonomic directions against a corpus of text.Our results show that popularity works as a proxy for generality in at most 90.91% of cases, but this can be improved to 95.45% using our approach, which should translate to higher-quality tag hierarchy structures.
