Guarani/Disambiguation

Initial ambiguity evaluation

The initial ambiguity of the corpus is 1.31922611850060459492.

Finding ambiguity

One source of ambiguity are the pronouns. The personal pronouns and the possessive pronouns both take the same form. This can cause ambiguity in sentences such as the following:

• Che pyhare porã (My night is good/well), which analyzes to the following:
  • ^Che/che<prn><nom><poss><p1><sg>/che<prn><nom><pers><p1><sg>$ ^pyhare/pyhare<n><sg>$ ^porã/porã<adj>$^./.<sent>$

In this case, we would want the possessive analysis of che (meaning "my"), not the personal analysis of che (meaning "I").

• Che aguata (I walk), which analyzes to the following:
  • ^Che/che<prn><nom><poss><p1><sg>/che<prn><nom><pers><p1><sg>$ ^aguata/guata<v><ar><pres><p1><sg>$^./.<sent>$

In this case, we would want the personal analysis of che, not the possessive analysis.

Final Ambiguity Evaluation

After adding the constraint rule and adding several words to the lexc file, the ambiguity became 1.32790988735919899875. I think there was only a small decrease in ambiguity because there weren't too many examples of this ambiguous case in the corpus.
