Chamorro to Bikol

Pluralizing Nouns

The item I chose to deal with in structural transfer is plural nouns. In Chamorro, a prefix is added to a noun to make it plural, while in Bikol, a separate lemma is added before the noun to pluralize it.

• Example sentence: You are teachers.
  • Chamorro: Manmaʼestro hamyo
  • Bikol: Mga maéstro kamó

Here are the outputs for the following modes after structural transfer was implemented for plural nouns.

• tagger: ^Maʼestro<n><pl>$ ^hamyo<prn><px2pl>$^.<sent>$
• biltrans: ^Maʼestro<n><pl>/Maéstro<n>$ ^hamyo<prn><px2pl>/kamó<prn>$^.<sent>/.<sent>$
• chunker:

apertium-transfer: Rule 2 Maʼestro<n><pl>/Maéstro<n>

apertium-transfer: Rule 1 .<sent>/.<sent> ^nm<pl>{^mga<pl>$}$ ^n<Noun>{^Maéstro<n>$}$ ^default<default>{^kamó<prn>$}$^sent<SENT>{^.<sent>$}$

• interchunk: ^nm<pl>{^mga<pl>$}$ ^n<Noun>{^Maéstro<n>$}$ ^default<default>{^kamó<prn>$}$^sent<SENT>{^.<sent>$}$
• postchunk: ^mga<pl>$ ^Maéstro<n>$ ^kamó<prn>$^.<sent>$
• cha-bcl: mga Maéstro #kamó

tagger, biltrans, chunker, interchunk, postchunk, and the pair itself (abc-xyz)
