Mission

• To effectively search multiple knowledge sets?
• Process needs to be intuitive
• Organization is imperative
• Answers need to be precise (of course!)
• Dont want to create more confusion

3
Approaches

• Meta Searching
• Search everything at once
• Controlled Searching
• Need to begin with a core set of data.
• Index
• Taxonomy

4
Meta Searching

• Meta Searching is the buzz
• Search everything at once

5
Difficulties in Meta Searching

• Not all databases are created equal
• Different Thesauri
• Different Vocabularies
• Different Engines
• Different Formats
• Z39.50 Is one solution
• Well we all know what that means!

6
Example

• User searches on Clinton and campaign finance
  reform
• Search Web, Biographies, Business, Health, News,
  OPAC, Reference
• Results are either organized in categories or
  combined.

7
Results

• Confusing at best
• Why search bibliographies for campaign finance
  reform?
• Doesnt highlight related or relevant topics and
  figures to the original query.
• Doesnt add any intelligence into the process.
• Navigating from one set to another.

8
