3 June 10 - June 16 1,172 1,501 61.60% 91.57%,79.04% 75.85%,62.90% WER for 'lin-eng' went up because of an incomplete rule for verbs that creates unnecessary pronouns. Main work next week will be on rules to dramatically improve WER and PER.
4 June 17 - June 23 1,200 1,540 69.70% 62.70% 79.27%,64.24% 84.41%,72.58%

7 July 8 - July 14 1,236 1,577 69.35% 60.47% 60.59%,46.47% 72.61%,58.68% Work was done on lexical selection and rules about determinants. Current lexical selection works well with the text currently in use, which is a more rigid and literary Lingala. Further tests will be run on texts from the Wikipedia corpus to generalize lexical rules.
8 July 15 - July 21 1,280 1,580 72.81% 68.62% 52.62%,42.82% 59.04%,46.28% WER went down in both directions by approximately 2% after I added accents, and missing ɔ́ ɔ ɛ́ ɛ. Next focus will be on negation and trying to find a bigger corpus(>1000 words).
9 July 22 - July 28 1,320 1,600 73.24% 68.92% 50.02%,41.55% 52.81%,40.09%
10 July 29 - Aug 04 Work was mainly on lexical selection rules. First half of Bible translation(~1,100 words) is understandable.
11 Aug 5 - Aug 11 1,341 1,661 75.35% 69.33% 48.97%,39.18% 53.99%,41.49% Lexical selection rules for 'na' and 'ya'. WER in eng-lin went up because I commented out some words in the bidix.
12 Aug 12 - Aug 18 77.06% Added missing morphology for determinants and adjectives.

Notes

  • To count stems in lexc, try:
 grep -E ":\w+.*;" apertium-lin.lin.lexc | grep -v "[<>]" | wc -l
  • To count stems in the bidix, try this:
 grep "<p" apertium-eng-lin.eng-lin.dix  | wc -l
  • To get WER and PER use apertium-eval-translator-line
