Erratum
After publication of the original article [1] it was noted that the captions relating to Figs. 2 and 3 had been interchanged.
An implemented graphical user interface of TEER for temporal expression extraction
The scalability evaluation of TEER (the first) and TEER_C (the second) using the increasing number of temporal expressions randomly selected from the testing datasets
These errors were introduced during typesetting; thus the publisher apologizes for this error. The correct figures and corresponding captions are shown below.
