# The begin offset is the mention's first character offset in the original
# text, while the end offset is the mention's last character offset in the
# original text + 1.
# The element of miRNA numbers is also a list, containing the number suffixes
# for the recognized miRNA. For example, for the name 'miR-206/21', the numbers
# are 206 and 21.
