Results So Far ...
- No guidelines for building better interactive IR systems yet. Plausible results require:
- a stable test environment
- “replication” within that environment
- testing in other settings
- Rich sets of process and result data about specific variations on a common task.
- Data to improve future research:
- data on variability to use in estimating sample sizes
- estimates of main effects and interactions of principal factors: searcher, system, topic
- sample experimental design and analysis
