Automatic folksonomy construction from tags has attracted much attention recently. However, inferring hierarchical relations between concepts from tags has a drawback in that it is difficult to distinguish between more popular and more general concepts. Instead of tags we propose to use user-specified relations for learning folksonomy. We explore two statistical frameworks for aggregating many shallow individual hierarchies, expressed through the collection/set relations on the social…

Constructing folksonomies by integrating structured metadata
TLDR
This work describes an approach to folksonomy learning based on relational clustering that addresses challenges by exploiting structured metadata contained in personal hierarchies by clusters similar hierarchies using their structure and tag statistics, then incrementally weaves them into a deeper, bushier tree.
Constructing Folksonomies by Integrating Structured Metadata with Relational Clustering
TLDR
This work describes an approach to folksonomy learning based on relational clustering that addresses challenges by exploiting structured metadata contained in personal hierarchies by clusters similar hierarchies using their structure and tag statistics, then incrementally weaves them into a deeper, bushier tree.
Growing a tree in the forest: constructing folksonomies by integrating structured metadata
TLDR
This work describes an approach to folksonomy learning based on relational clustering, which exploits structured metadata contained in personal hierarchies and clusters similar hierarchies using their structure and tag statistics, then incrementally weaves them into a deeper, bushier tree.
Pragmatic evaluation of folksonomies
TLDR
This paper presents and applies a pragmatic framework for evaluating folksonomies, and model exploratory navigation of a tagging system as decentralized search on a network of tags, to use hierarchical structures learned by folksonomy algorithm as background knowledge for decentralized search.
Improving on Popularity as a Proxy for Generality When Building Tag Hierarchies from Folksonomies
TLDR
The results show that popularity works as a proxy for generality in at most 77 of cases, but that this can be improved to 81% using the improved approach proposed, which will translate to higher quality tag hierarchy structures.
Automatic Construction of a Folksonomy-Based Visual Ontology
TLDR
Results indicate that the proposed method to extract hierarchical structure on relations between tags from Folksonomy is promising and the structure is expected to help image search and some other applications.
Ontology emergence from folksonomies
TLDR
An ontology induction approach to harvest the emergent semantics from the folksonomies is developed and an agglomerative hierarchical clustering algorithm utilizing the result of tag generality ranking to generate the concept hierarchy is proposed.
A probabilistic approach for learning folksonomies from structured data
TLDR
An unsupervised probabilistic approach that extends affinity propagation to combine the small ontological fragments into a collection of integrated, consistent, and larger folksonomies, which yields better overall integration quality than a state-of-the-art approach based on incremental relational clustering.
Comparing the hierarchy of author given tags and repository given tags in a large document archive
TLDR
A recent method is applied to check the differences and similarities of hierarchies resulting from tags giving by independent individuals and from tags given by a centrally managed repository system.

Improved annotation of the blogosphere via autotagging and hierarchical clustering
TLDR
It is found that tags are useful for grouping articles into broad categories, but less effective in indicating the particular content of an article, and clustering algorithms can be used to reconstruct a topical hierarchy among tags.
An Unsupervised Model for Exploring Hierarchical Semantics from Social Annotations
TLDR
This paper proposes an unsupervised model to automatically derive hierarchical semantics from social annotations and demonstrates that the derived hierarchical semantics has the ability to compensate those shortcomings.
Exploiting Social Annotation for Automatic Resource Discovery
TLDR
A probabilistic model of the user annotation process in a social bookmarking system del.icio.us is described and results show this approach as a promising method for helping automate the resource discovery task.
Semantic Taxonomy Induction from Heterogenous Evidence
TLDR
This work proposes a novel algorithm for inducing semantic taxonomies that flexibly incorporates evidence from multiple classifiers over heterogenous relationships to optimize the entire structure of the taxonomy, using knowledge of a word's coordinate terms to help in determining its hypernyms, and vice versa.
HT06, tagging paper, taxonomy, Flickr, academic article, to read
TLDR
A model of tagging systems, specifically in the context of web-based systems, is offered to help illustrate the possible benefits of these tools and a simple taxonomy of incentives and contribution models is provided to inform potential evaluative frameworks.
Deriving concept hierarchies from text
TLDR
This paper presents a means of automatically deriving a hierarchical organization of concepts from a set of documents without use of training data or standard clustering techniques, using a type of co-occurrence known as subsumption.
Learning Concept Hierarchies from Text Corpora using Formal Concept Analysis
TLDR
A novel approach to the automatic acquisition of taxonomies or concept hierarchies from a text corpus based on Formal Concept Analysis, which model the context of a certain term as a vector representing syntactic dependencies which are automatically acquired from the text corpus with a linguistic parser.
