int.ere.st: SCOT-based Tag Sharing Services Hak Lae Kim and John Breslin Blogtalk 2008 Cork, Ireland Social Software Group {haklae.kim, john.breslin}@deri.org

I will talk about Why Do We Need to Share Tags? Tag Tagging Tagcloud Folksonomies structure semantics data format SCOT mashups OpenTagging semantic web sharing social networks int.ere.st

OpenTagging Platform

OpenTagging Platform

OpenTagging Platform an open framework that is scalable and interoperable with all existing tagging data from heterogeneous sources or applications http://opentagging.org Goals to make tagging data open, more universal, and apply it across any number of social tagging sites Through continuously user participations on the platform, users can make their customized folksonomies to organize their data by their needs and interests The interaction of diverse objects such as users, tags, and resources on the platform brings emergent semantics of tagging data and leverages social connections among participants

Goals

to make tagging data open, more universal, and apply it across any number of social tagging sites

Through continuously user participations on the platform, users can make their customized folksonomies to organize their data by their needs and interests

The interaction of diverse objects such as users, tags, and resources on the platform brings emergent semantics of tagging data and leverages social connections among participants

Three core components Open Data Format These aim for specifying tagging data in a formal way. The data formats for common conceptualization of tagging data can be represented by an ontology to make a minimal commitment. Methods and APIs aims to collect, share, or exchange tagging data, or create a bridge among heterogeneous social tagging sites, methods should implement by types of mashups Platform supports a social ecosystem that interlinks among diverse objects such as individual and individual, individual and communities, or individual and the tags themselves and leverages social connections based on tags.

A Meaning of Tag ( http://moat-project.org )

Gruber’s Conceptual Model Core Concepts Tag: a word or phrase that is recognizable by people and computers Object: a thing to be tagged, identifiable by a URI or a similar naming service Tagger: someone or thing doing the tagging, such as the user of an application Tagged: the assertion by Tagger that Document should be tagged with Term Tagging(Object, Tag, Tagger, Source)

SCOT Ontology Social Semantic Cloud of Tags aims to describe the structure and the semantics of tagging data and to offer social interoperability of the data among heterogeneous sources is to provide social structure of tagging for seamless tag sharing across heterogeneous users, applications or sources

Platform for OpenTagging

int.ere.st Overview Goal: to realize the OpenTagging platform SCOT based representation for tagging data methods for search, compare or integrate tagging data Open APIs to get tagging data Provide a tagging, bookmarking, and sharing service for social tagging data Provide a uniform way to share, exchange, and reuse tagging data among users, communities, or sources Links among tagging data with Semantic Web vocabularies ( SIOC, FOAF, SKOS, DC, MOAT )

Goal: to realize the OpenTagging platform

SCOT based representation for tagging data

methods for search, compare or integrate tagging data

Open APIs to get tagging data

Provide a tagging, bookmarking, and sharing service for social tagging data

Provide a uniform way to share, exchange, and reuse tagging data among users, communities, or sources
