                                DESCRIPTION

Motivation
The Web 2.0 world provides users with tools for generating a growing and 
meaningful part of Web contents; in fact, everyday an increasing number 
of users collaborates by sharing/publishing resources, associating tags 
on documents, and remixing existing contents. This process of 
information and knowledge construction increases the amount of resources 
making hard manual tasks such as the retrieval of interesting contents, 
or the selection of meaningful tags for classifying documents.

Collaborative tagging systems, such as del.icio.us or bibsonomy, are 
popular examples of tools, which allow users to conceptualize, describe, 
and share resources. Users can assign a set of tags simplifying the 
search of bookmarked resources and providing indications to other peers. 
But, actually there is not effective usage of tags: typically tags are 
applied just for a personal consumption and people associate different 
meaning to the same tag; tagging systems are not based on well defined 
vocabularies, and so many tags do not provide any help to a user.
Recommender systems aim at reducing the effort required to users, by 
modeling users’ preferences and goals. The Web 2.0 philosophy creates a 
new role for the user which can be modeled both as a consumer of 
information and as a producer of new contents. But the development of 
recommendation frameworks based on the analysis of tags is still an open 
challenge.

This special session aims at discussing the state-of-art, open problems, 
challenges and innovative approaches in designing and developing 
intelligent mechanism for personalized collaborative tagging systems. In 
particular, we are interested in  algorithms and frameworks able to 
model users in social tagging environment and provide user with tags for 
simplifying the organization of interesting resources and with 
suggestions concerning resources filling the users information needs.

Objectives
This special session aims at discussing the state-of-the-art, open 
problems, challenges and innovative research approaches in recommending 
tags and resources in social tagging systems.
Examples of stimulating application fields are recommendation in social 
bookmarking environments, publication sharing systems, or, more in 
general, digital libraries 2.0.
Three specific questions motivate this special session:

1. How users’ interests, goals and preferences can be modeled in social 
tagging systems?

2. What models, techniques, and tools are the most adequate in order to 
overcome folksonomies’ limitations and to provide plausible and useful 
recommendations?

3. How much the usage of tags for generating recommendations can improve 
results of other existing recommender systems?




                                     TOPICS

The topics of interest for the workshop are listed below. All them have 
to be considered in the context of social tagging systems.

the special session, will be considered as well.
