Constraint-based lexical selection for rule-based machine translation
Corpus: cawiki-20110616-pages-articles.xml.bz2
cleaned with `aq-wikicrp'
1758582 lines
531983 unique analyses
531436 lines with >1 translation (30%)
2740 analyses with >1 translation
287 words (lemma+pos) with >1 translation in corpus
712 words in dictionary with >1 translation
1.03 fertility of dictionary over corpus (e.g. total number of word:word translations / total number of words)
Test corpus:
- 150 test words
- 1,500 sentences
- 10 per test word
- Randomly selected from the subset of sentences which were found in the corpus.
- Only words with >100 example sentences included
- Rationale: Dictionary doesn't provide good enough coverage to produce statistically significant results over a whole corpus.
Training corpus:
Baselines:
- TL Frequency-best
- TLM-best
- Linguist set
- Full analysis:Full analysis dic from Giza++
- Rules from phrase table
