Final Evaluation

gug → wbp and wbp → gug

100 more stems

Added 100 more stems (mostly nouns, verbs, and adjectives) to the bilingual and monolingual dictionaries.

gug → wbp

3 new lexical selection rules

  • (gug) akã → (wbp) jurru "head"; payarrpa "hill"
    • Rule: Select "jurru" (Eng: head) as the translation of "akã" when it is preceded by "ha'e" (Eng: his/her). Otherwise, select "payarrpa" as the default.
  • (gug) asu → (wbp) jampu "left"; jampu-karra "left-handed"
    • Rule: Select "jampu-karra" (Eng: left-handed) as the translation of "asu" when it is followed by person words such as "ava" (Eng: person) or "kuña" (Eng: woman) or "mitã" (Eng: child). Otherwise, select "jampu" (Eng: left) as the default.
  • (gug) henyhẽ → (wbp) jaka-ngalya "full"; ngayarrka "pregnant"
    • Rule: Select "ngayarrka" (Eng: pregnant) as the translation of "henyhẽ" when it is followed/preceded by "kuña" (Eng: woman) or other words describing female people. Otherwise, select "jaka-ngalya" (Eng: full) as the default.

6 additions to the morphology

  • Added numeral analysis:
    • Several number words in Warlpiri also have meanings as nouns (e.g. rdaka can mean "hand" or "five")
    • the -pala ending distinguishes them as number words, but it is not always necessary
    • "rdaka-pala": ^rdaka-pala/rdaka<num>$^./.<sent>$
    • "rdaka": ^rdaka/rdaka<num>/rdaka<n><sg><abs>$^./.<sent>$
  • Added adverb analysis:
    • "nyurruwiyi: ^nyurruwiyi/nyurruwiyi<adv>$^./.<sent>$
  • Added elative/source case for verb auxiliaries :
    • "kajangka": ^kajangka/ka<vaux><src><subj3sg>$^./.<sent>$
  • Added inceptive aspect for verbs:
    • "pakarnunjunu": ^pakarnunjunu/pakarni<v><tv><past><inc>$^./.<sent>$
  • Added possessive marker "nyanu" for nouns:
    • "kaja-nyanu-rlu": ^kaja-nyanu-rlu/kaja<n><pl><poss><erg>$^./.<sent>$
  • Added the topicalizing particle grammatical marker for nouns. -ja is used to mark known information or to indicate the topic, although sometimes it has no function.
    • echo "kurdukuju": ^kurdukuju/kurdu<n><sg><dat><top>$^./.<sent>$


4 new disambiguation rules

  • Number vs Noun (e.g. rdaka = hand or five), has the number marker -pala
  • Manu = cnjcoo vs v tv past?
  • Kuja = "ka" vaux rel subj3sg OR kuja = kuja cj. relative pronoun, what, which, that, who.
    • Kuja = "ka" vaux rel subj3sg OR kuja = kuja cj. relative pronoun, what, which, that, who.
    • Ngula = "ka" vaux rel subj3sg OR kuja = kuja cj. relative pronoun, what, which, that, who. Find by searching AUX:COMP in new dictionary
