ContactDuplicate detection and clustering¶
It sure does. If you currently have an FDMS bulk download, or a large
collection emails in Lotus Notes or Microsoft Outlook and you suspect it
has mass email campaign duplicates, you can now run the de-duplication
and clustering algorithms inside PCAT. Here is an example:
Users of PCAT can relax the threshold for identifying duplicates and
sample “clusters” of near-duplicate comments generated by form letter
and talking point campaigns. This step makes it easier to both document
the dimensions of the central “talking points” while also focusing
attention on unique or otherwise unexpected contributions.
