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.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
