Word ambiguity, if a word of the same type has two meanings, like race as a sport event and race as a sociological concept is at present not handled in apertium.

Some examples for ambiguous words are:

  • race (sociological race or sporting race)
  • spirit (alcohol or morally)
  • coach (trainer or travelling mean)
  • dull (event or knife)
  • fall (season, human, part of the landscape)

A suggestion for ambiguity handling:

1. dictionary contains all meanings, order: most possible... less possible.

2. we find real meaning be lemmas in the neighbourhood of the word. In case of race_match the words match, bet, run, sport are for example related words. In case of race_sociology the words discrimination, hatred, human are for example related words. Related words are stored as lower case lemmas, and matching must be also done in lemma form.

3. The algorithm looks:

  • found ambiguous word.
  • if in sentence related words, select meaning. (go from most to less probable meaning)
  • if no related words in sentence, select most probable word.

4. Dictionary looks:

  • <word>race__match<word><related_words>match,bet,run,sport</related_words>
  • <word>race__sociology<word><related_words>discrimination,hatred,human</related_words>

5. Obtaining neighbouring words. The words in the same sentence are the first candidates. If any related words found in them, case solved. If not, algorithm checks the words in the previous 10 sentences. These will be weighted, the nearer to our sentence, the higher the weight. If matches found, the match with the highest weight will be considered.

An example text: This sport car is black. Peter has experienced problems of discrimination. The car race is in Ashton.

In that example the algorithm using the listed related words will decide for race_sociology, since discrimination is the nearest matching candidate. The example illustrates, how important is to select the right related words.
