Evaluation of Coordination Techniques in Synchronous Collaborative Information Retrieval.
Foley C and Smeaton A.F. JCDL Workshop on Collaborative Information Retrieval, Pittsburgh, PA., 20 June 2008. [BibTex] [08-37] 
Traditional Information Retrieval (IR) research has focussed on a single user interaction modality, where a user searches to satisfy an information need. Recent advances in web technologies and computer hardware have enabled multiple users to collaborate on many computer-supported tasks, therefore there is an increasing opportunity to support two or more users searching together at the same time in order to satisfy a shared information need, which we refer to as Synchronous Collaborative Information Retrieval (SCIR). SCIR systems represent a significant paradigmatic shift from traditional IR systems. In order to support effective SCIR, new techniques are required to coordinate users' activities. In addition, the novel domain of SCIR presents challenges for effective evaluations of these systems. In this paper we will propose an effective and re-usable evaluation methodology based on simulating users searching together. We will outline how we have used this evaluation in empirical studies of the effects of different division of labourand sharing of knowledge techniques for SCIR. Workshop Website.

Collaborative Video Searching on a Tabletop.
Smeaton A.F, Lee H, Foley C and Mc Givney S. Multimedia Systems Journal, 2006. (pp375-391) [BibTex] [06-63] 
Abstract Almost all system and application design for multimedia systems is based around a single user working in isolation to perform some task yet much of the work for which we use computers to help us, is based on working collaboratively with colleagues. Groupware systems do support user collaboration but typically this is supported through software and users still physically work independently. Tabletop systems, such as the DiamondTouch from MERL, are interface devices which support direct user collaboration on a tabletop. When a tabletop is used as the interface for a multimedia system, such as a video search system, then this kind of direct collaboration raises many questions for system design. In this paper we present a tabletop system for supporting a pair of users in a video search task and we evaluate the system not only in terms of search performance but also in terms of user-user interaction and how different user personalities within each pair of searchers impacts search performance and user interaction. Incorporating the user into the system evaluation as we have done here reveals several interesting results and has important ramifications for the design of a multimedia search system. Article from SpringerLilnk. Synchronous Collaborative Information Retrieval with Relevance Feedback.
Foley C, Smeaton A.F and Lee H. CollaborateCom 2006 - 2nd International Conference on Collaborative Computing: Networking, Applications and Worksharing, Atlanta, Georgia, 17-20 November 2006. (pp1-4) [BibTex] [06-65]
Collaboration has been identified as an important aspect in information seeking. People meet to discuss and share ideas and through this interaction an information need is quite often identified. However the process of resolving this information need, through interacting with a search engine and performing a search task, is still an individual activity. We propose an environment which allows users to collaborate to satisfy a shared information need. We discuss ways to divide the search task amongst collaborators and propose the use of Relevance Feedback, a common Information Retrieval process, to enable the transfer of knowledge across collaborators during a search session. We describe the process by which co-searchers can collaborate effectively with little redundancy and how we can combine Relevance Judgements from multiple searchers into a coherent model for Synchronous Collaborative Information Retrieval. Conference Website. Físchlár-DiamondTouch: Collaborative Video Searching on a Table.
Smeaton A.F, Lee H, Foley C, Mc Givney S and Gurrin C. SPIE Electronic Imaging - Multimedia Content Analysis, Management, and Retrieval, SPIE Vol. 6073, San Jose, CA, 15-19 January 2006. [BibTex] [06-02]
In this paper we present the system we have developed for our participation in the annual TRECVid benchmarking activity, specifically the system we have developed, Físchlár-DT, for participation in the interactive search task of TRECVid 2005. Our back-end search engine uses a combination of a text search which operates over the automatic speech recognised text, and an image search which uses low-level image features matched against video keyframes. The two novel aspects of our work are the fact that we are evaluating collaborative, team-based search among groups of users working together, and that we are using a novel touch-sensitive tabletop interface and interaction device known as the DiamondTouch to support this collaborative search. The paper summarises the backend search systems as well as presenting the interface we have developed, in detail. Link to Full-text on SPIE DL. Collaborative Searching for Video Using the Físchlár System and a DiamondTouch Table.
Smeaton A.F, Foley C, Gurrin C, Lee H and Mc Givney S TableTop2006 - The 1st IEEE International Workshop on Horizontal Interactive Human-Computer Systems, Adelaide, Australia, 5-7 January 2006. (pp149-156) [BibTex] [06-01]
Físchlár-DT is one of a family of systems which support interactive searching and browsing through an archive of digital video information. Previous Físchlár systems have used a conventional screen, keyboard and mouse interface, but Físchlár-DT operates with using an horizontal, multi-user, touch sensitive tabletop known as a DiamondTouch. We present the Físchlár-DT system partly from a systems perspective, but mostly in terms of how its design and functionality supports collaborative searching. The contribution of the paper is thus the introduction of Físchlár-DT and a description of how design concerns for supporting collaborative search can be realised on a tabletop interface.

TRECVid 2005 Experiments at Dublin City University.
Foley C, Gurrin C, Jones G, Lee H, Mc Givney S, O'Connor N, Sav S, Smeaton A.F and Wilkins P. TRECVid 2005 - Text REtrieval Conference TRECVID Workshop, Gaithersburg, Maryland, 14-15 November 2005. [BibTex] [05-70]
In this paper we describe our experiments in the automatic and interactive search tasks and the BBC rushes pilot task of TRECVid 2005. Our approach this year is somewhat different than previous submissions in that we have implemented a multi-user search system using a DiamondTouch tabletop device from Mitsubishi Electric Research Labs (MERL).We developed two versions of our system one with emphasis on efficient completion of the search task (fischlar-DT Efficiency) and the other with more emphasis on increasing awareness among searchers (fischlar-DT Awareness). We supplemented these runs with a further two runs one for each of the two systems, in which we augmented the initial results with results from an automatic run. In addition to these interactive submissions we also submitted three fully automatic runs. We also took part in the BBC rushes pilot task where we indexed the video by semi-automatic segmentation of objects appearing in the video and our search/browsing system allows full keyframe and/or object-based searching. In the interactive search experiments we found that the awareness system outperformed the efficiency system. We also found that supplementing the interactive results with results of an automatic run improves both the Mean Average Precision and Recall values for both system variants. Our results suggest that providing awareness cues in a collaborative search setting improves retrieval performance. We also learned that multi-user searching is a viable alternative to the traditional single searcher paradigm, provided the system is designed to effectively support collaboration.

Smeaton A.F, Foley C and Mc Donald K. ISWC2005 - 4th International Semantic Web Conference, Galway, Ireland, 6-10 November 2005. [BibTex] [05-61]
The development of a semantic web of text, images, structured information, and continuous media information including video and audio, depends on being able to annotate content with semantic meaning and then use that content description directly in applications. Annodex is a recently announced initiative to allow continuous media files to be integrated directly with their own content description, into one unified source. In this short paper we take a state of the art video indexing, browsing and retrieval system, Físchlár-News, whose architecture and design is based on a separation of content from content description, and we re-engineer it using Annodex. In doing this we demonstrate the improvements this new approach makes over our system and the increased opportunities it offers in terms of functionality. Conference Website.
