Spring 2006 DLF Forum: Melvyl Recommender Project, 6

3 April, 2006

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.
