Future of Information Integration

1
Future of Information Integration?

• Kevin C. Chang
• University of Illinois, Urbana-Champaign

Or, it seems
Integration is always in the future? We have been
5 years away from there for a while.

Be optimistic. We are hopeful

• Our commitments never stop
• Phil B. has declared metadata as another hair pie
  that he would like to address
• Alon H. has declared semantic resolution as
  lifelong goal
• Plus, many juniors will swear in today
• Or, the problem may go away
• NSF deleted DB (IDM), added integration (SEIII)
• so database increasing will slow down, and
  integration can eventually catch up

Learn from reality Fact sheet.

• Data is on the Web
• Web is the ultimate data repository that we have
  accessed
• User is the people
• People have been under-served for their
  information access
• Funding is on applications
• Applications are what NSF claims to have funding
  for

5
Learn from history The reviving of information
retrieval

• Traditionally focused on library scenarios,
  subscription-based text archives.
• The field has not thrived
• The Web has revived IR
• People as the consumers and publishers
• Huge cool factor!
• Killer application for pre-AI techniques
• With the large scale, bar is relatively low
• New insights emerged to change the paradigm
• With the large scale, new approaches are possible

6
Future 1 In terms of problem.
Web is the Future. As both a killer
application and a novel domain.
7
Web information integration Challenges

• Large scale integration
• Dynamic source discovery and modeling
• Application driven
• Facilitate domain-based integration
• User centered
• Enable ad-hoc on-the-fly integration

8
Future 2 In terms of agenda.
Integration is the future! Need deliverables.
Put things together.
9
Never too early Think about system integration

• Before working on abstract problems
• What is the big picture and context?
• The specific applications may give unique
  insights
• Beyond isolated abstract problems
• What can we deliver?
• Define and engineer a product is non-trivial
