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

Background

Tag : free-text keyword created by a human being
Tagging : indexing process assigning tags to resources
Folksonomies : collections of tags that are created in social tagging
Tagcloud : visualization tool for folksonomies
Tag, Tagging, Folksonomies

User engagement & easy-to-use
Increased refindability
More metadata!
Advantages of Tagging

Disadvantages of Tagging
Ambiguity
Findability
Accuracy
Portability
structure and semantics for tagging data might be a solution

Why Do We use Tags?

What Do We Expect from Tagging? Why Do We Need to Share Tags?

Where is “Your” Tag Clouds?

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

Open Data Format

Goals OpenTagging Platform Open Data Formats Methods and APIs Interoperation & Portability social connections Existing Tag Sources OpenTagging Spaces Desktop Web Mobile

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.

Open Data Format

Tag Ontologies for Data Format
Structure and Semantics for Tagging data
Gruber’s conceptual idea ( http://tomgruber.org/writing/ontology-of-folksonomy.htm )
Richard Newman’s Tag Ontology ( http://www.holygoat.co.uk/projects/tags )
Torben Knerr’s Tagging Ontology ( http://code.google.com/p/tagont/ )
Tag Schema ( http://tagschema.com/blogs/tagschema/ )
Henry Story’s Tagging Schema ( http://blogs.sun.com/bblfish/entry/search_tagging_and_wikis )
Sharing and Exchanging for Tagging data
Tagcommons.org ( http://tagcommons.org )
Social Semantic Cloud of Tags ( http://scot-project.org )
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)

Newman’s Tag Ontology

Tagging Example

How do we contain each tagging activity?

Social Semantic Cloud of Tags

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
