gravitas numbers

I've found that, as Arnold suggests, you can use a collection of
high-frequency, high-diffusion items as a proxy for database size --
items like "among," "fix," "book," "behalf" and so forth. One problem
with this is that in the most widely used interface, in addition to
having items like "the" on its stop list, Nexis won't return hit
counts over 1,000. In that case you can either take a time-slice (say
one month a year), or do a conjunctive search (e.g., on articles
containing "fix," "buy," and "friend"), or choose some
lower-frequency items like "revoke" and "estimation." While all these
methods are approximate, I've found as Arnold has that they don't
vary too widely from counts done on high-frequency functors like
"the." And given the noise introduced by factors like article
duplication, none of these estimates is going to be exact in any
event.
