Unified Functional Testing (UFT) is a commercial software test automation tool owned by Micro Focus, formerly owned by Hewlett Packard (HP) and Hewlett Packard Enterprise (HPE). This tag specifically refers to version 14 of this software.
uft14 should be considered a synonym for hp-uft, although this software is no longer owned by Hewlett Packard (HP), hence the potential reason for the use of this separate tag.
