[Corpora-List] ANNOUNCE: Link-Grammar version 4.7.0

[Linas Vepstas]

Version 4.7.0 of the Link Grammar Parser is now available.  This version
introduces a major restructuring of the manner in which conjunctions are
handled.  Conjunctions are no longer indicated with "fat links"; instead,
a half dozen new link types (non-fat, of the ordinary kind) are introduced.
This allows for a more careful and precise treatment of conjunctions; it
significantly reduces the number of exceptional cases handled in the C code,
and results in faster parser: from 1.3x to 2.7x faster, depending on the
text.  The new technique is described here:

WHAT IS LINK GRAMMAR?
The Link Grammar Parser is a syntactic parser of English (and other
languages as well), based on link grammar, an original theory of English
syntax. Given a sentence, the system assigns to it a syntactic
structure, which consists of a set of labelled links connecting pairs of
words. The parser also produces a "constituent" (Penn tree-bank style
phrase tree) representation of a sentence (showing noun phrases, verb
phrases, etc.). The RelEx extension provides dependency-parse output.
