constraint grammar造句

The basic original reference is Karlsson ( 1990 ) which defines Constraint Grammar.
In computational linguistics Karlsson has designed a language-independent formalism called Constraint Grammar.
Some current major algorithms for part-of-speech tagging include the Viterbi algorithm, Brill tagger, Constraint Grammar, and the Baum-Welch algorithm ( also known as the forward-backward algorithm ).
CG systems can be used to create full syntactic trees in other formalisms by adding small, non-terminal based phrase structure grammars or dependency grammars, and a number of Treebank projects have used Constraint Grammar for automatic annotation.
The Constraint Grammar concept was launched by Fred Karlsson in 1990 ( Karlsson 1990; Karlsson et al ., eds, 1995 ), and CG taggers and parsers have since been written for a large variety of languages, routinely achieving accuracy F-scores for part of speech ( word class ) of over 99 %.
