INLS 180 Day 15 Notes
Note most recent JASIST has
several bibliometrics papers
Main Points
Relevance is key ILS concept:
indexing/aboutness, evaluation, ranking
There are absolute (classfications, systems, objective) or relative
(user-centered, subjective) definitions of relevance
Possible relationships
between relevance and quality (and authority)
Indexing is based on
objective relevance
Questions
If relevance is strictly
‘relative’ how can we have effective retrieval systems (libraries, www)?
Can we ever get 100% recall
and precision? How close do we get?
Will transaction log metrics
improve relevance metrics?
How does personal agreement
with content affect relevance judgments? [against
subjective]
Can a system determine
quality?
Are there standards for
quality?
Can we use non-binary
concepts of relevance?
2. A diversion: Instead of trying to address retrieval as matching queries to docs with similarity measures that estimate relevance formally, bring the information seeker directly into the process. Interactive interfaces and dynamic query examples.
