INTRODUCTION

The continued growth and importance of the Social Web has resulted in ever increasing volumes of data created, published and consumed by users. This vast amount of data takes many forms, including text, images, video and more recently streams of status information from applications such as Facebook and Twitter. Not only is this data accessible through more traditional means, such as desktop and laptop computers, but also via diverse platforms such as mobile devices and set-top boxes that bring unique constraints in terms of computing resources, interaction modes and user interfaces. Through the increasing availability of Web APIs, data that has traditionally been coupled with a specific application may now be exposed through novel interfaces developed by third parties, providing functionality not previously anticipated by data owners.

In tandem with the growth of the Social Web, the Web at large has experienced a significant evolution into a Web not just of linked documents, but also of Linked Data. This development, which exploits the Semantic Web technology stack, allows relationships to be expressed between items in distributed data sets, paving the way for integration of raw data from multiple, heterogeneous sources. Coupled with the increasing availability of APIs that expose data from the Social Web, application developers have a wealth of data available to them upon which they can build compelling visual interfaces. Furthermore, in context of recent developments, such as Facebook introducing Open Graph Protocol, Twitter enabling tweets with annotations and Google moving into the Semantic Web with their acquisition of Metaweb, interactions on the Social and Semantic Web are gaining a larger audience.

In this context, the ability to easily integrate vast amounts of data from across the Social and Semantic Web raises significant and exciting research challenges, not least of which how to provide effective access to and navigation across vast, heterogeneous and interconnected data sources. However, the need for intelligent and visual human interfaces to this evolving Web is not limited simply to the modalities of searching and browsing, important as these are. As the Web becomes increasingly populated with data, continues to evolve from a read-mainly to a read-write medium, and the level of social interaction supported on the Web increases, there is also a pressing need to support end-users who engage in a wide range of online tasks, such as publishing and sharing their own data on the Web. Exploring different aspects of those developments and their implications for visual interface research and development is one of the goals of the workshop.

This workshop aims to bring together researchers and practitioners from diverse, complementary fields to discuss the latest research results and challenges in designing, implementing, and evaluating intelligent interfaces in the context of the Social or Semantic Web. The workshop will serve as an opportunity for researchers to gain feedback on their work, and to identify potential collaborations with their peers. We believe that the potential for fostering links between a variety of facets of the IUI community will help to ensure an exciting workshop program.

TOPICS OF INTEREST

Topics of interest include, but are not limited to:

* Interfaces
o Novel interfaces for high-volume transient data, e.g. feeds, streams and sensors.
o Novel interfaces supporting discovery of social data and richer interactions using Facebook's Open Graph Protocol, Twitter's Annotations for tweets, Google's Social Graph etc.
o 'Living' interfaces to constantly evolving data, vocabularies, and emerging links between them.
o Collaborative interfaces supporting social data analysis.
o Adaptive user interfaces on the Web.
o Lightweight components and processes for casual users to publish/share their own content on the Web.
o Task-centric interfaces for structured and/or Linked Data.
o Novel visualisation of structured, linked and aggregated data, originating from multiple sources.
o Interface components for displaying/interacting with aggregated, heterogeneous Linked Data, e.g. components for displaying provenance information.
o Ontology-based visualization of collections of data.

* Interaction Paradigms
o Novel (e.g. touch-based, gesture-based, etc.) interaction paradigms for textual, photos, music, videos, etc. on various platforms (e.g. mobile devices, set-top boxes, shared/public single/multiple displays).
o Investigation of task-centric interaction paradigms beyond search and browse.
o Novel interaction paradigms with structured, linked and aggregated data.
o Ontology-based interaction with collections of data.
o Semantic models for interaction and their reuse on the web

* Empirical Studies and Evaluation
o Use cases which present novel visualization requirements and expose interesting interaction challenges on the Social and Semantic Web.
o Empirical studies that can guide the development of interfaces for Linked Data.
o Implications for design from user-studies, pilot systems and live deployments in the Social and Semantic Web.
