The author is referring to coordinate transformations, the mathematical concept.
See (random internet link) Coordinate Transformations for instance.
tf is a library that makes handling such transforms in the context of robotics applications in ROS almost trivial, hence the popularity of it (and many references to it) in ROS.

From the wiki/tf2 page:
tf2 is the second generation of the transform library, which lets the user keep track of multiple coordinate frames over time. tf2 maintains the relationship between coordinate frames in a tree structure buffered in time, and lets the user transform points, vectors, etc between any two coordinate frames at any desired point in time.
And see #q270403 for a related question.
