TUCCUP 2011 - Contextualized Usage and Attention Metadata: Towards unobtrusive context creation and usage in enriched platforms (TUCCUP)

Recent years have brought advances in content analysis techniques for multimedia content. However, the semantic gap is still present. The levels of performance obtained for text-based search and recommendation are not yet fully scalable to more complex interactive environments including multiple applications, devices or resource types such as image/audio/video. To currently understand the nature, quality and/or relevance of a resource in a specific context, analyzing the content alone might not be sufficient. Other sources of information have to be taken into account as well. This includes the context of resources, attention paid to it and actions taken on it by users.
Information about the attention users give to resources and how they are used (e.g. number of streaming accesses on a video in a period, the type of tasks being executed while using a resource, at which time a resource is accessed, whether a video is watched completely or not, from which country ratings are made, etc.) can be used to improve retrieval relevance, to help recommend resources, or simply to identify the respect context of the user in which the task is being carried out. To be useful, this information needs to be first systematically collected into potentially large datasets. There are open challenges on how to store this information, how to aggregate and merge it over heterogeneous systems, how to distill the data into information and then into knowledge about the resources and how to use this knowledge to build or enhance multimedia applications.
The objective of this workshop is to research content- and user-centric as well as context-aware methodologies, technologies and systems for tracking and managing usage and attention metadata from different applications.
The workshops invites papers dealing with the following topics. Please note that, as the research field has by no means reached a mature state, papers of ongoing work are very much welcome!
Topics of interest for the workshop include, but are not restricted to:
Capture and aggregation of usage and attention metadata for resources;
Recommender systems to assist users in finding relevant content based on usage and attention metadata;
Frameworks for the management of usage and attention metadata for heterogeneous resources;
Creating semantic information from user attention;
Contextualization of multimedia resources;
Social aspects, such as ownership, privacy and business models for the capture and use of usage and attention metadata;
Applications that use usage and attention metadata, including but not limited to applications in science, engineering, humanities, business, public safety, commerce, and technology enhanced learning.
Regarding usage and attention metadata itself, this workshop is aimed also to be a place to discuss the technological and social challenges in capturing, storing and using attention information. Efficient and scalable ways in which this information could be shared between different tools and systems is one of the main technological issues to be dealt with. On the social side, the acceptance that different ownership/exploitation approaches have with end users and investors will determine the success or failure of attention metadata-based applications. Researchers and practitioners confronting these topics are among the desired attendance of this workshop.
