Thad, linking may be easier with FAST[1] than LCSH. LCSH is 
pre-coordinated, so it has strings like:

Confucianism --China --Rituals.

which won't match any topics outside of the library world. FAST has 
taken LCSH and broken the pre-coordinated topics into separate statements:

Confucianism
China
Rituals

FAST is available as linked data.
