bdb51a244e [phrases] fix case in trie search when searching for tokens in a string tail. If we're on the last token in a sequenence and the token matches the tail, check that the tail is complete, and if so return the match before exiting the loop. Affects multiword phrases that tend to appear toward the end of a sequence (long country names like "United States of America", etc.) 2016-12-29 16:17:09 -05:00

acd953ce51 [parser] first pass at new parser feature extraction 
- removing geodb phrases
- use Latin-ASCII-simple transliteration (no umlauts, etc.)
- no digit normalization for admin component phrases and postcodes
- tag = START + word, special feature for first word in the sequence
- add the new admin boundary categories
- for hyphenated non-phrase words, add each sub-word
- for rare and unknown words, add ngram features of 3-6 characters with
  underscores to indicate beginnings and endings (similar to language
  classifier features)
- defines notion of "rare words" (known words with a frequency <= n where
  n > the unknown word threshold), so known words can share
  statistical strength with artificial and real unknown words
