.SH NAME
link-parser \- parses natural language sentences

.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
In Selator, D. and Temperly, D. "Parsing English with a Link Grammar"
(1991), the authors defined a new formal grammatical system called a
"link grammar". A sequence of words is in the language of a link
grammar if there is a way to draw "links" between words in such a way
that the local requirements of each word are satisfied, the links do
not cross, and the words form a consistent connected graph. The authors encoded
English grammar into such a system, and wrote \fBlink\-grammar\fP to
parse English using this grammar.
.PP
This package can be used for linguistic parsing for information
retrieval or extraction from natural language documents. Abiword also
uses it as a grammar checker.

.SH USE
.PP
link\-grammar, when invoked manually, will take control of the
terminal; link\-grammar will then attempt to analyze the grammar of
all input, unless escaped with an exclamation mark, according to the
dictionary file provided as an argument. If escaped, the input
will be treated as a "special command"; "!help" lists all special
commands available.
.PP
link\-grammar depends on a link\-grammar dictionary which contains
lists of words and associated metadata about their grammatical
properties in order to analyze sentences. A link\-grammar dictionary
provided by the authors of link\-grammar is usually included with the
link\-grammar package, and can often be found somewhere in the
/usr/share/link\-grammar/ hierarchy. When this is the case, only the
two\-letter language code needs to be specified on the command\-line.
Alternatively, a user can provide
their own dictionary as an argument, in which case the dictionary's
directory should be specified. Hence, either of the commands
.TP
.B link\-grammar en
.TP
.B link\-grammar /usr/share/link\-grammar/en
will run link\-grammar using the english dictionary included with the
parser.

While in a link\-grammar session, some example output could be:

link\-grammar can also be used non\-interactively, either through its
API, or via the \-batch option. When used with the \-batch option,
link\-grammar passively receives input from standard input, and when
the stream finishes, it then outputs its analysis. So one could
construct an ad\-hoc grammar checker by piping text through
link\-grammar with a batch option, and seeing what sentences fail to
parse as valid:
.RS
.B cat thesis.txt | link\-grammar /usr/share/link\-grammar/en/4.0.dict \-batch
