Chamorro/Disambiguation
Code
Initial Evaluation of Ambiguity
Initial ambiguity is 1.345 (2031 analyses of 1510 tokens).
- Many of the ambiguous forms are pronouns. The way the transducer works at this moment, I gave every pronoun the ability to be analyzed in any person and number. I wasn't sure if this was the best way to go about it, but it does cause a lot of multiple analyses in this disambiguation phase. Also, this initial evaluation includes the two sentences (listed below) that I added to the corpus to test the disambiguator so that the size of the corpus would be constant before and after this step.
Example
Words can sometimes be either nouns, verbs, or adjectives depending on the surrounding context. For example, the word 'dánkolo' takes a different grammatical role in the two following sentences:
- Hu liʼeʼ i dánkolo (I saw the big one)
- Hu liʼeʼ i dánkolo na taotao (I saw the big person)
In the first sentence, the word serves as a noun because there is no other noun later in the sentence. However, in the second sentence, the noun 'taotao (person)' is present, making 'dánkolo' into an adjective. I believe that in any sentence of the form of the second sentence, the noun that the adjective modifies will be exactly two words away. Therefore, the constraint that I will use is that every time that a noun is two words after the adjective/noun ambiguous word, the transducer should select the adjective analysis of the word. Conversely, whenever this context does not appear, I will force the transducer to default to the noun reading.
Final Evaluation of Ambiguity
Final ambiguity is 1.344 (2029 analyses of 1510 tokens).
- This makes sense because the disambiguation rule I wrote focused specifically on a single construction that did not appear at all in my original corpus. Therefore, the only two sentences with ambiguities removed were the two that I added to test whether the rules were working.
