Pragmatic evaluation of folksonomies

Denis Helic, Markus Strohmaier, Christoph Trattner, Markus Muhr, Kristina Lerman
2011 Proceedings of the 20th international conference on World wide web - WWW '11  
Recently, a number of algorithms have been proposed to obtain hierarchical structures -so-called folksonomies -from social tagging data.  ...  We model exploratory navigation of a tagging system as decentralized search on a network of tags.  ...  In this paper, we focus on navigating the tag-tag graphs, to mimic tag-based navigation.  ...

Evaluation of Folksonomy Induction Algorithms

Markus Strohmaier, Denis Helic, Dominik Benz, Christian Körner, Roman Kern
2012 ACM Transactions on Intelligent Systems and Technology  
In social tagging systems, the output of these algorithms is usually referred to as folksonomies (from folk-generated taxonomies).  ...  In addition to adopting semantic evaluation techniques, we present and adopt a new technique that can be used to evaluate the usefulness of folksonomies for navigation.  ...  In this paper, we focus on navigating the tag-to-tag network (based on a tag-to-resource network), to mimic a tag-based user navigation task.  ...

Personalized recommendation in social tagging systems using hierarchical clustering

Andriy Shepitsen, Jonathan Gemmell, Bamshad Mobasher, Robin Burke
2008 Proceedings of the 2008 ACM conference on Recommender systems - RecSys '08  
Our basic recommendation framework is independent of the clustering method, but we use a context-dependent variant of hierarchical agglomerative clustering which takes into account the user's current navigation  ...  We present a personalization algorithm for recommendation in folksonomies which relies on hierarchical tag clusters.  ...  The freedom to navigate through all three dimensions of the folksonomy is central to its utility.  ...

Harvesting social knowledge from folksonomies

Harris Wu, Mohammad Zubair, Kurt Maly
2006 Proceedings of the seventeenth conference on Hypertext and hypermedia - HYPERTEXT '06  
Collaborative tagging systems, or folksonomies, have the potential of becoming technological infrastructure to support knowledge management activities in an organization or a society.  ...  This paper presents designs that enhance collaborative tagging systems to meet some key challenges: community identification, ontology generation, user and document recommendation.  ...  Through tag-based navigation users can discover who created a given tag, and see the other tags that this person has created.  ...

Intelligent Interface Architectures for Folksonomy Driven Structure Network [article]

Massimiliano Dal Mas
2012 arXiv   pre-print
The practice of tagging is done in a collective environment. Folksonomies are self constructed, based on co-occurrence of definitions, rather than a hierarchical structure of the data.  ...  On this base a Human-Computer Interactive (HCI) systems is developed for the visualization, navigation, updating and maintenance of folksonomies Knowledge Bases - the FSN - through the web.  ...  It is considered the concept of "Folksodriven Structure Network" to represent folksonomies based on the use of folksonomies and network theory.  ...

Computational and Crowdsourcing Methods for Extracting Ontological Structure from Folksonomy [chapter]

Huairen Lin, Joseph Davis
2010 Lecture Notes in Computer Science  
This paper investigates the unification of folksonomies and ontologies in such a way that the resulting structures can better support exploration and search on the World Wide Web.  ...  Promising results have been obtained from experiments using tag datasets from Flickr and Citeulike.  ...  Most of hierarchical clustering algorithms are based on bottom-up methods. First it computes pairwise tag similarities, and then merges most similar tags into groups.  ...

An Integrated Approach to Extracting Ontological Structures from Folksonomies [chapter]

Huairen Lin, Joseph Davis, Ying Zhou
2009 Lecture Notes in Computer Science  
Collaborative tagging systems have recently emerged as one of the rapidly growing web 2.0 applications.  ...  In turn, the flat and non-hierarchical structure with unsupervised vocabularies leads to low search precision and poor resource navigation and retrieval.  ...  Aiming to converting a large corpus of tags from folksonomy into a navigable hierarchical taxonomy of tags, an algorithm using graph centrality has been proposed.  ...
