Lingsoft English parser

Description

ENGCG, the Constraint Grammar Parser of English, performs morphosyntactic analysis (tagging) of running English text. The parser employs a morphological ("part-of-speech") disambiguator that makes 93-97% of all running-text words in Written Standard English unambiguous while 99.7% of all words retain the correct analysis. The corresponding figures for the shallow syntactic parser are 75-85% and 97-98%
