Metadata Mechanisms: From Ontology to Folksonomy ... and Back

Using a Folksonomy Approach for Location Tagging in Community Based Presence Systems

“…Folksonomies are often put forward as an alternative to or reaction against categorizations based on formal taxonomies or ontologies [2]. One basic difference between these two approaches is whether a categorization or model is seen as something static that can be created in advance as in the ontology case, or if it is something that is created and updated as a part of an ongoing activity, as in the folksonomy case.…”

Information Retrieval and Social Tagging for Digital Libraries Using Formal Concept Analysis

“…As a result the museum's formal classification schema is now simple and less error-prone. Social tagging may produce surprisingly stable structures [11], which may lead to emergent and dynamic taxonomies [2], [4], [16] although there is an open problem in ensuring that terms are used consistently within the tagging process -previous applications that use unstructured and non-normalised meta-data to construct formal contexts have resulted in concept lattices that are almost unusable for navigation and search [8]. However term stemming, the use of and lexical databases such as WordNet [17] can be used overcome the problem of synonymous tags.…”

No mining, no meaning

“…In "The Guide" [27], another effort to join folksonomies and ontologies, the tags assigned by users are classified within a controlled taxonomy built by domain experts and connected to an ontology to execute an enhanced document retrieval and a better user finding. In this approach, as in the ones mentioned before, document categorization still depends on users' capacity (or will) to generate the metadata, and not on the content of the document itself.…”
