Homographs

Two or more words are homographs when they have the same graphic form (they are written in the same way) but with different meanings.

In Italian and English there are thousands of homographs.

T-LAB implements disambiguation routines that reduce their impact. In particular, multiword normalization and compound verb tense identification.

For example, the normalization of the sequence "at present" (modified in "at_present") allows us to distinguish "present" as gift and "present" as time.
