3. Why?
Improve response times
Greater flexibility to create a system that had end user
concerns as a priority
Expose all our resources through a single point of entry
Combine IT knowledge with knowledge of library
science
4. How
Integrated search
Speed and meaningful ranking of material from
different sources
Exploratory search
Help users find what they are looking for – even if
they don't quite know it themselves
Motivational design
Show users the information they need when they
need it
5. “Facets” – Limit Your
Search
Limit your search to certain material types
6. Facets – No Counts
Proper facets. The facet counts came later.
8. Facet Information
Current system at the State and University Library
9.1 million records
8.7 million unique tags in 15 facets
Average number of tags/document is 10
Large facets
Subject: 3.5 million unique tags
Author: 4.8 million unique tags
10. Recent Usability Test:
The Good
The Google-like initiatives
One simple search field
Search suggestions
Did-You-Mean
The integration of extra information in the full records –
especially covers and abstracts
The Todo list
11. Recent Usability Test:
What To Improve
Users had trouble finding journal articles
Many users failed to discover the facets
Further tweaking of the relevancy ranking
Simplification of the request procedure
15. More Data
User expectations: If they can't find it in Search, then we
don't have it.
Particularly a problem with article level data.
Will make the experience as a whole better for the end
user.
17. Clustering
Add clustering framework to facilitate automatic tag
extraction.
May link together articles, books, and data-sets that the
user hadn't thought of.
Should prove very useful with full text data.
18. Other
Rights integration
Duplicate reduction
User specific ranking
Further develop system and statistics tools
Index look-ups
And more...
