Query: Funding acknowledgment analysis:Queries and Caveats   Thomson Reuters' Web of Science (WoS) began systematically collecting
acknowledgment information in August 2008. Since then, bibliometric analysis of
funding acknowledgment (FA) has been growing and has aroused intense interest
and attention from both academia and policy makers. Examining the distribution
of FA by citation index database, by language, and by acknowledgment type, we
noted coverage limitations and potential biases in each analysis. We argue that
in spite of its great value, bibliometric analysis of FA should be used with
caution.
