Big +1 for promoting the use of the Authority Control Wikipedia
template.I know i'm being a bit of a broken record, but you can watch
as people add these by looking at or subscribing to:

Also, re: Jonathan's good advice to check out Wikipedia Miner [1] I
just ran across Duke [2] today, which looks like it could help guide
record linking a bit.

"""
Duke is a fast and flexible deduplication (or entity resolution, or
record linkage) engine written in Java on top of Lucene. At the moment
(2011-04-07) it can process 1,000,000 records in 11 minutes on a
standard laptop in a single thread.

Haven't tried it yet, so YMMV, etc.
