Presentation Transcript

  1. Machine Translation with Scarce Resources The Avenue Project

  2. Scarce Resources • Not much text in electronic form. • Very few linguists who can write computational rules. • No standard orthography • Kudaw, kusaw (work) (Mapudungun, Chile) • Not even sure of pronunciation: • EH-nvelope, AH-nvelope (envelope) (English, US, not a language with scarce resources)

  3. Our Approach • Learn rules from a controlled corpus. • Corpus is elicited from bilingual speakers. • The informant only needs to translate and align words.

  4. AVENUE Project • New Ideas • Use machine learning to learn translation rules from native speakers who are not trained in linguistics or computer science. • Multi-Engine translation architecture can flexibly take advantage of whatever resources are available. • Research partnerships with indigenous communities in Latin America and Alaska (Mapudungun (Chile), Siona (Colombia), Inupiaq (Alaska)) Interface for data elicitation • Impact • Rapid and low-cost development of machine translation for languages with scarce resources. • Policy makers can get input from indigenous people. • Indigenous people can participate in government and internet. Schedule Year 1: Seeded Version Space learning– first version Year 2: Example-Based Machine Translation of Mapudungun (Chile). Year 3: Multi-Engine Mapudungun system (EBMT and partially learned transfer rules) Carnegie Mellon University, Language Technologies Institute: L. Levin, J. Carbonell, A. Lavie, R. Brown

  5. Elicitation Interface

  6. Elicitation Corpus: example English : I fell. Spanish: Caí Mapudungun: Tranün English: I am falling. Spanish: Estoy cayendo Mapudungun: Tranmeken

  7. Elicitation Corpus: example English: You (John) fell. Spanish: Tu (Juan) caiste Mapudungun: Eymi tranimi (Kuan) English: You (Mary) fell. Spanish: Tu (María) caiste Mapudungun: Eymi tranimi (Maria) English: The rock fell. Spanish: La piedra cayó Mapudungun: Trani chi kura
