Spring 2006 DLF Forum: Melvyl Recommender Project,

Testbed
●
Bibliographic records
–
MARC export from Melvyl
–
~4.2 million UCLA records used in the current
prototype
–
Experimented with using UCB records as well, for a
total of 9 million
●
To build our testbed, we extracted UCB and UCLA data (9 million records total)
Considered broader/narrower datasets
- (e.g. all UCLA/UCB, circulating only, w/ISBNs only)
-
UCLA approximates union catalog mix, avoids merge
-
AND most important, we have good circulation data, used in other portions of the project.
