Link Grammar .Net

[proai]

I ported Link Grammar (4.1) to .NET I was attempting to convert the
new Linux friendly version and so far I can't even get them (any of
the versions) to compile. I have tried all the sugestions in this
group to no avail. I have made some progress but still won't
compile. I have already spent more time trying to get it to compile
that it took me to port the old version to .NET. Has anyone tried to
get this working in .NET? I am concerned that even if I do get it to
compile it still won't work for what I need it to do.

I was wondering how compatible the new dictionaries are to the 4.1
dictionaries? I like the fact that the api is now being maintained
but it seems that it is going in a different direction. I am a little
fustrated and trying to see if there is anything here I can use or if
I need to start over and port the entire lib to .NET (I'll make it run
in mono).

No one can help you if you don't indicate what the
problem is.

The new dictionaries will not work with the old parser,
because the new dictionaries contain UTF8 characters.
The old dictionaries should work with the new parser.

The API has not changed at all, except to vastly simplify
dictionary loading, which used to be very buggy and
unreliable.

The API has not changed at all, except to add some new routines to
simplify dictionary lading.

Just to see what the differences are I wrote a quick BNF parser using
Irony for the dictionary and wow, they are very different. the UTF8
Chars made my parser very unhappy. The old dictionary (4.1) parses no
problem the new one makes defining a valid identifer a bit tricky but
since you guys are making a word processor I can see why you took that
route.


the errors I am getting using MingW32 are:

api.c: In function `post_process_linkages':
api.c:872: error: implicit declaration of function `rand_r'
api.c:872: warning: nested extern declaration of `rand_r'

If anyone is interested, here is the code for an irony LinkGrammar
Grammar (needs some work to read a 4.5.5 dictionary though:

var singleLineComment = new CommentTerminal
("SingleLineComment", "%", "\r", "\n", "\u2085", "\u2028", "\u2029");
NonGrammarTerminals.Add(singleLineComment);
var identifier = new IdentifierTerminal("identifier", "+-
*._,", "‘0123456789-@/’'$");
var literal = new StringLiteral("qouted","\"");
var ruleExpr = new NonTerminal("ruleExpr");
var expr = new NonTerminal("exression", typeof
(StatementListNode));
var binaryExpression = new NonTerminal("binaryExpression",
typeof(BinExprNode));
var binaryOperator = new NonTerminal("binaryOperator");
var identifierList = new NonTerminal("identifierList");
var expressionList = new NonTerminal("expressionList");
var term = new NonTerminal("term");
term.Rule = identifier | "<" + identifier + ">" | literal;
identifierList.Rule = term | term + identifierList;
expr.Rule = identifierList + ":" + ruleExpr + ";";
binaryOperator.Rule = Symbol("&") | "or";
ruleExpr.Rule = term | binaryExpression | "(" + ruleExpr +
")" | "{" + ruleExpr + "}" | "[" + ruleExpr + "]" | "()";
binaryExpression.Rule = ruleExpr + binaryOperator +
ruleExpr;
expressionList.Rule = expr | expr + expressionList;
Root = expressionList;
RegisterOperators(1, "&", "or");
RegisterPunctuation("(", ")");
RegisterPunctuation("[", "]");
RegisterPunctuation("{", "}");
RegisterPunctuation(";");
RegisterPunctuation(NewLine);
Delimiters = "{}[]();:";

These were reported only a few days ago by evgenii,
and I think these are now fixed in the latest svn.

try getting the latest svn, then grabbing utilities.h
from that, and copying it into your build directory.

I think that should fix things.

Hi Proai,

I'm not sure I understand correctly, do you have a working .NET port
of Link Grammar 4.1?
If so, could you post it please?
Thanks.

Yes I do, it is available at http://proai.com/cs/files/7/default.aspx

port, or bindings? I assume you mean "bindings" not "port".
