Workshop: Interactive Information Access - Untangling Tasks and Technologies

Tuesday December 7th, Centrum Wiskunde & Informatica (CWI), Amsterdam, NL


Maarten Clements will defend his PhD thesis Personalised Access to Social Media on Monday 6th December at 12:30, at the Technical University of Delft.

Alia Amin will defend her PhD thesis Understanding and Supporting Information Seeking Tasks Across Multiple Sources (.pdf) on Wednesday 8th December at 10:00, at the University of Amsterdam, Agnietenkapel.

In honour of both these events and as part of the Advanced Components Stage of the SIKS program we are organising a workshop entitled Interactive Information Access: Untangling Tasks and Technologies on Tuesday 7th December, at CWI, Amsterdam (event on facebook).


10:30-11:00 Coffee and welcome
11:00-11:45 Mor Naaman (Rutgers University), Interacting with Social Media Content about Events

Social media sites (e.g., Flickr, YouTube, Twitter and Facebook) are a popular distribution outlet for users looking to share their event experiences on the Web. These sites host substantial amounts of user-contributed materials from, or about, a wide variety of events of different type and scale. I will describe two interactive "social multimedia" systems that attempt to improve the experience of consuming the large amount of content associated with specific events. First, I will present a multi-perspective video player designed for viewers to consume user-contributed videos taken while attending an event. Second, I will describe a visual analytic tool designed to help journalists and media professionals extract news value from aggregations of textual social media content about large-scale broadcast events. Using qualitative methods, with scenarios and tasks tied to user's goals and motivated and driven by existing user needs, we performed an evaluation for both applications that allowed us to collect meaningful feedback that can inform not only our own, but others' work in that area.

This work was done at the Social Media Research Lab at Rutgers SC&I. The project is partially funded the National Science Foundation and Nokia, and is looking for a fantastic PhD student to lead its future work.

11:45-12:30 Hyowon Lee (Dublin City University), Issues in Designing Novel Applications for Multimedia Technologies

Emerging computational multimedia tools and techniques promise powerful ways to organise, search and browse our ever-increasing multimedia contents by automating annotation and indexing, augmenting meta-data, understanding media contents, linking related pieces of information amongst them, and providing intriguing visualisation and exploration front-ends. Identifying real-world scenarios and designing interactive applications that leverage these developing multimedia technology is certainly an important research topic in itself but poses a number of challenges. In this talk, I will discuss and highlight some of these challenges in designing these novel applications by reflecting on my own design practice with a number of design examples.

12:30-13:30 Lunch
13:30-14:15 Ichiro Ide (Nagoya University), Untangling the Semantic Structure in a Broadcast Video Archive

Large amounts of video data can be stored online, thanks to the advancement of digital storage technology. At NII (National Institute of Informatics) in Japan, we have built a broadcast video archive, named NII TV-RECS, that automatically records and stores all seven terrestrial TV channels broadcast in Tokyo. In this talk, I introduce several on-going projects that aim to analyze the semantic structures in the archives, and to recompile the video data into new video contents based on the analyzed structure so that they can be used for video story-telling.

14:15-15:00 Diane Kelly (University of North Carolina), Relevance Feedback for the Modern Searcher: Elicitation Techniques Revisited

One of the first interactive features in information search systems was term relevance feedback where the system presented terms to the searcher and the searcher then selected which terms were relevant to his/her information need. Term relevance feedback - and relevance feedback more generally - has been a common interactive technique in both experimental and commercial systems since the 1960s, even though it has been largely dismissed by interactive information retrieval researchers who claim that explicit elicitation techniques require too much effort, are cognitively demanding and are cumbersome and clunky. In this talk, I will review both past and present techniques for eliciting relevance feedback from searchers, present past explanations for why these techniques were/are not used and argue that these explanations are no longer adequate in today's search environments.
