author-wise normalized metrics

Hello.

In updating my ResearcherID record, I faced some challenges.

A

Is there a way to automatically count the number of authors of a publication?

B

Is there a way to normalize (i.e. divide) the number of citations received by a publication to the number of authors of that publication? This seems to be possible, e.g. in the NASA ADS.

C

Is there a way to limit the number of citations received by a publication to a given year (say 2010), without looking into that publication’s citation record?

Thanks.
