This document discusses the need for sharing tags across different systems and platforms. It proposes using SCOT (Social Semantic Cloud of Tags), an ontology for representing tagging data, and the OpenTagging platform for enabling interoperability among tags from different sources. The OpenTagging platform uses SCOT's data model and provides APIs to retrieve, search, and integrate tagging data from various social tagging applications and services in a unified manner. This allows tags to be portable and shared across different users, communities and sources.

3. Background

4. 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

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

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

16. OpenTagging Platform

17. 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

18. Open Data Format

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

20. 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.

22. 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 )

23. 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)

30. Social Semantic Cloud of Tags

31. 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

38. 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 )

39. How int.ere.st works? Weblogs Web 2.0 sites Desktops or Mobile share retrieve aggregate
