PUBLIC MARKS with tags folksonomies & folksonomy

Ontologies are enabling technology for the Semantic Web. They are a means for people to state what they mean by formal terms used in data that they might generate or consume. Folksonomies are an emergent phenomenon of the social web. They are created as people associate terms with content that they generate or consume. Recently the two ideas have been put into opposition, as if they were right and left poles of a political spectrum. This piece is an attempt to shed some cool light on the subject, and to preview some new work that applies the two ideas together to enable an Internet ecology for folksonomies.

Deux services américains, del.icio.us et Flickr ont donné le ton, en permettant aux utilisateurs de “taguer” eux-mêmes le contenu qu’ils proposent ou souhaitent partager en ligne....(Internet actu 13/10/2005)

Plutôt que de démarrer avec un titre barbare, Ed a astucieusement choisit un titre révélateur pour la communauté des futurs bibliothécaires de son département : « Et si les lecteurs avaient le choix d'organiser le classement des livres. » Il s'agit tout à fait de cela et rien de plus.

* Misspelt tags (e.g., libary, libray) * Badly encoded tags, such as unlikely compound word groupings (e.g.,TimBernersLee) * Tags that do not follow convention in issues such as case and number; singular versus plural form (e.g., apple, apples) * Personal tags that are without meaning to the wider community (e.g., mydog) * Single-use tags that appear only once in the database. (e.g., billybobsdog)

1. Introduction A folksonomy is a type of distributed classification system. It is usually created by a group of individuals, typically the resource users. Users add tags to online items, such as images, videos, bookmarks and text. These tags are then shared and sometimes refined. A general review of social bookmarking tools, one popular use area of folksonomies, was given in the April edition of D-Lib [1]. In the article the authors elaborate on the approach taken by social classification systems and the motivators behind tagging. They write, "...tags are just one kind of metadata and are not a replacement for formal classification systems such as Dublin Core, MODS, etc.... Rather, they are a supplemental means to organise information and order search results."
