This poster summarizes the results from a quantitative analysis of the tags and associated metadata used to describe more than one million videos by 537,246 contributors at the YouTube video sharing site. Results from this work suggest methodological and design considerations that could enhance the effectiveness of sharing within communities devoted to(More)
To support effective browsing, interfaces to digital video libraries should include video surrogates (i.e., smaller objects that can stand in for the videos in the collection, analogous to abstracts standing in for documents). The current study investigated four variations (i.e., speeds) of one form of video surrogate: a fast forward created by selecting(More)
We describe a minimalist methodology to develop usage-based recommender systems for multimedia digital libraries. A prototype recommender system based on this strategy was implemented for the Open Video Project, a digital library of videos that are freely available for download. Sequential patterns of video retrievals are extracted from the project's web(More)
The future will bring widespread access to large digital libraries of video. Consequently, a great deal of research is focused on methods of browsing and retrieving digital video. This type of work requires that investigators acquire and digitize video for their studies since the video information retrieval community does not yet have a collection of video(More)
The Open Video Project is specifically concerned with the surrogates that can represent the objects in a digital video collection and the mechanisms through which people can manipulate those surrogates. In TREC VID 2003, we compared the effectiveness of a transcript-only search system, a features-only search system and a search system combining transcript(More)
Digital libraries have the potential to not only duplicate many of the services provided by traditional libraries but to extend them. Basic finding aids such as search and browse are common in most of today's digital libraries. But just as a traditional library provides more than a card catalog and browseable shelves of books, an effective digital library(More)
The Open Video Project is an on-going effort to develop an open source digital video collection that can be used by the research community and ultimately serve an even broader audience. The initial collection contains video or metadata for more than 1600 digitized video segments comprising nearly half a terabyte of content. Our primary goals for this(More)
A framework for interface design that provides people with flexible control over different views for an information space is presented. The agileviews framework defines overviews, previews, reviews, peripheral views, and shared views that help people make decisions about where they should focus attention during information seeking. In addition to the views(More)
In a digital environment, it is feasible to integrate multimedia materials into a library collection with ease. However, it seems likely that non-textual surrogates for multimedia objects, e.g., videos, could effectively augment textual representations of those objects. In this study, five video surrogates were evaluated in relation to their usefulness and(More)
