    1. Unimpeded Discovery of Digital Content - Intro - Günter Waibel/RLG My role is to briefly introduce Blaise and give some context to the technology he’ll show you. When he first demonstrated his technology at RLG, 30 year veterans of the information age said “This is the most amazing thing I’ve seen since Mosaic” (the first web browser). You’ll see for yourselves in just a minute, and I think you’ll agree that this technology has far-reaching implications for our community. I won’t even try to describe what it looks like, all I’ll say now is that it has the potential to radically change the way we think about interfaces and retrieval in digital libraries.My role is to briefly introduce Blaise and give some context to the technology he’ll show you.

    2. Recognition over Recall “Recognition occurs when you see something familiar, while recall requires that you remember something and are able to articulate it.” “Most information retrieval depends upon recall skills – the user has to describe what he or she wishes to retrieve.” “Recognition approaches are likely to be much more effective in large digital libraries of the future […]” - Borgman, Christine L. Personal digital libraries: Creating individual spaces for innovation. http://www.sis.pitt.edu/~dlwkshop/paper_borgman.pdf To set the context, let me ponder for a second these quotes up on the screen. Christine Borgman outlines the two basic search paradigms we’re all familiar with Recognition – looking for something familiar. Its equivalent in information seeking behavior would be browsing. Recall – looking for something very precise. Its equivalent in information seeking behavior would be searching. She goes on to stipulate that most current approaches to providing access to information depend upon recall, while to her mind recognition approaches would be much better suited to large digital libraries.To set the context, let me ponder for a second these quotes up on the screen.

    3. We have some experience with this at RLG. Log analysis and interviews with users shows that they prefer browsing over searching, or a more guided experience over a stab in the dark. On this screen, you can see the entire contents of the database broken out to answer three questions: What? Where? And Who?, allowing users to zero in on what they desire. In other words, we are trying to provide a recognition experience using descriptive metadata. Needless to say, this approach is heavily dependent on the quality of the descriptive metadata available.We have some experience with this at RLG.

    4. This is a more straightforward recognition experience. Users also have the option to display their results on a light-table. The benefit: visual information can be processsed much faster than textual information. However, for large result sets, there are still dozens or hundreds of pages to browse through, and the totality of information is never quite available in the same way as in the Results Overview.This is a more straightforward recognition experience.
