INLS 235
Day 4
1. One minute papers
Big point
Active vs passive acquisition
Quality control (whether to, how to)
How to choose what we keep; keeping transactions does not tell what people did with info
Quality vs usability/efficiency
Physical library CD policies will evolve with DLs
Surprised that ibiblio has some CD policy
Questions
Is interoperability a tool or a quality/capability?
Is an automatically culled set of resources from the web a DL?
If tools like collection synthesis get good, will people get lazy, not be able to search?
How does ibiblio maintain reputation without quality verification?
Can we measure the quality of a source systematically?
Will web crawlers acquire semantics?
How do capacities influence CD policies?
Is it worth making a poor quality digital object?
How will dynamic objects affect CD policies?
Is there any reason to automate CD except cost?
2. Project ideas
3. Multimedia
Special issues/requirements
Convergence (analog and digital cultures, careers, tools, design traditions, etc.)
Hardware (server and client side): special cards, processors, cables, cameras, flash memory
Software (DBMS models, e.g., blobs vs MMDBMS; indexing, browsers, e.g., plug ins), editing
Data management: formats (analog and digital), metadata
Access and use (how to query? (e.g., hum a few bars), QBE interfaces, interactive interfaces, tools to integrate (e.g., PP, Word)
Human behavior models (perceptual, cognitive, and affective processing and impacts)
Example video DLs
Informedia project http://www.informedia.cs.cmu.edu/
Fischlar project http://www.cdvp.dcu.ie/index.html

digitization boards (Broadway) and software for AVI/MOV to MPEG-1 and MPEG-2,
now QuickTime too
Merit (keyframe
extraction, UMCP), modified for Linux
VAST
Speech to text (Sphinx
version X, CMU)
Transaction log scripts (for
monitoring and recommenders)
ISEE
Peer to peer
exchange

Managing a server (security,
repairs, upgrades)
Tools and services for our users
studies
Database driven web pages for
user interaction
Usability workstation
(multiple camera, mixer, VCR)
Eye tracking system
