S P I D E RSharing Pertinent Information in Dynamically Evolving Repositories
• Projects generate large amounts of information– Proposals, Progress Reports, Results
• Projects comprised of loosely integrated teams need to keep members apprised of pertinent project information– Computer Science
• ETH,Clever,Social Assistant Project,CSLR
– Cognitive Science• Clever, CSLR
– Health Sciences

Why is this important?
• because, “Innovation comes from outside the city walls.” - Kouichi Kishida, SRA
• to avoid duplicative work
• to increase social capital--who knows what?
• to create opportunities for more fluid collaboration (the type that can exists within a group)

Searching and Browsing
“Ooooh, this is exciting! Our first practical application for the Internet!
OK, should I do a search under
‘pythons,’ ‘snakes,’ or
‘suffocation’?”

How do we keep up with evolving information?
Information delivery!

Approaches for Personalized Information Delivery
• Adaptable - the user can adapt the system to his or her needs (e.g., My Yahoo!)– Manber, U., Patel, A., & John, R. (2000). Experience with
Personalization on Yahoo! Communications of the ACM, 43(8), 35-39)
• Adaptive - system actively adapts to the user’s needs (e.g., Amazon.com)– Hirsh, h., Basu, C., & Davison, B. D. (2000). Learning to
Personalize. Communications of the ACM, 43(8), 102-106.– Mobasher, B., Cooley, R., & Srivastava, J. (2000).
Automatic personalization based on Web usage mining. Communications of the ACM, 43(8), 142 - 151.

BEA’s WebLogic Personalization Server
• Rule-based approach• User Attributes
– Enables the collection of metadata about users and their usage patterns
– e.g., last login date, books purchased -> interest
• Classifier Rules– Classifies Users based on their attributes– e.g., recent user,
• Selection Rules - Matches content (based on meta data) to user class (based on attributes)

What’s the Problem?
• Rule-based approach is OK for e-commerce because content and users are well-categorized by marketing groups– E.g., Books -> Romance, Mystery,, etc.
– E.g., Merchandise -> Automotive, Home Improvement, etc.
• Claim:Dynamic Information Repositories are too complex and large rule bases are unmanageable.

What’s the Solution?
• Some of the techniques mentioned are necessary but not sufficient
• Social Filtering - Amazon.com– “Dear Andrew Gorman, We have noticed that many of
our customers who have purchased albums by Kenny Burrell also enjoy music by Miles Davis…”
• Semantic Analysis (LSA?)– “Here are things that are similar to the things you (or
your group) have contributed.”

Who uses Information Repositories?

Social Factors affecting the adoption of information systems
• Disparity in work and benefit - “Who does the work and who receives the benefit?”
• Critical mass and Prisoner’s dilemma• Disruption of social process• Unobtrusive accessibility• Adoption process - Grassroots roots vs.. Mandate
Grudin, J. (1994). “Groupware and social dynamics: eight challenges for developers” Communications of the ACM, 37(1), 92-105)
