Constraint Grammar (CG) parsers are at the core of most of VISL's live
|
|
applications. The Constraint Grammar concept was launched by Fred
|
|
Karlsson in the early 90'ies (Karlsson et.al.1995), and CG parsers have
|
|
since been written for a large variety of languages, routinely achieving
|
|
F-scores for PoS (word class) of over 99%. A number of syntactic CG
|
|
systems have reported F-scores of around 95%. VISL's own Constraint
|
|
Grammar systems are inspired by Eckhard Bick's PALAVRAS parser for
|
|
Portuguese (Bick 2000), and use, as a novelty, subclause function,
|
|
generalized dependency markers and semantic prototype tags. For most
|
|
languages, a lexicon based morphological analyzer provides input to the
|
|
first CG level, while the output of the last CG-level can be converted
|
|
into syntactic tree structures by specially designed Phrase Structure
|
|
Grammars (PSG's), using syntactic functions, not words, as terminals.
|
|
Other, hybrid combinations are, however, feasible. Thus, the French
|
|
system uses PoS information from a probabilistic tagger.
