Web of Science Query Partitioner
WoS Query Partitioner is a tool that interactively splits a Web of Science query which returns more than 100,000 results into smaller queries to allow to easily obtain an exact result count.
It does work by splitting the query using the Source field (SO) in a kind of Divide and Conquer recursive strategy.
In addition the application offers two different kinds of graphs which depict the partitioning process as well as a LaTeX table output of the executed queries.
The details of its inner workings can be found in the associated paper:
