Subject: [0] Introduction

This guide lists Prolog resources: archives, newsgroups, books,
magazines, compilers, interpreters and anything else you can think of
which has to do with the proliferation of Prolog. Also included is a
list of suppliers of products and a list of publishers. As Prolog has
a strong historical tradition in Europe, we've tried to ensure that
the information is relevant to all readers, both European and North American.

This guide is posted regularly to comp.lang.prolog. It may also be
obtained by anonymous ftp from CMU:

   To obtain the file from CMU, connect by anonymous ftp to any CMU CS
   machine (e.g., ftp.cs.cmu.edu [128.2.206.173]), using username
   "anonymous" and password "name@host". The file prolog-resource-guide.txt
   is located in the directory
       /afs/cs.cmu.edu/user/mkant/Public/AI/
   [Note: You must cd to this directory in one atomic operation, as
   some of the superior directories on the path are protected from
   access by anonymous ftp.] If your site runs the Andrew File System,
   you can just cp the file directly without bothering with FTP.

   We have taken great care in making the information in this document as
   accurate as possible. However we are not responsible for any problems
   which might occur from using information supplied in this guide.

Subject:  [1]  Sources of information about Prolog

The newsgroups comp.lang.prolog and (to a lesser extent) comp.ai are a
source of information and discussion about Prolog. 

A "Frequently Asked Questions" posting is posted to comp.lang.prolog
twice a month by Jamie Andrews <jamie@cs.sfu.ca>. The Prolog FAQ and this
Prolog Resource Guide are intended to complement one another.

Subject: [2]  Public Domain or Free Prolog Implementations

The following list of free Prolog implementations excludes those listed
in the comp.lang.lisp FAQ (i.e., Prolog interpreters written in Lisp).
Note that commercial prolog implementations are often more robust and
better supported than public domain and free prolog implementations. 

   A.D.A. Public Domain Prolog:
      aisun1.ai.uga.edu:ai.prolog/adapdpro.zip

      A rather slow implementation of Prolog for MS-DOS systems, originally
      a product of Automata Design Associates (now defunct), 1570
      Arran Way, Dresker, PA 19025, 215-335-5400. 


   ALF:

      ALF (Algebraic Logic Functional programming language) is a
      language which combines functional and logic programming techniques.
      The foundation of ALF is Horn clause logic with equality which
      consists of predicates and Horn clauses for logic programming, and
      functions and equations for functional programming.  The abstract
      machine is based on the Warren Abstract Machine (WAM) with several
      extensions to implement narrowing and rewriting.  In the current
      implementation programs of this abstract machine are executed by an
      emulator written in C. It is available by anonymous ftp from
      ftp.germany.eu.net (aka simpson.germany.eu.net) in the directory
      /pub/programming/languages/LogicFunctional as the files alf_*.zoo
      (Documentation, C sources for the emulator, the preprocessor and the
      compiler). For further information, contact Rudolf Opalla
      <opalla@julien.informatik.uni-dortmund.de>.


   BinProlog:
      clement.info.umoncton.ca:BinProlog/binpro.1.39.tar.Z [139.103.16.2]
      The file papers.tar.Z contains papers related to the implementation.

      BinProlog is free for research and other non-profit purposes. Version
      1.39 runs on Sparc, Sun3, NeXT, and 386/486. The compiler makes 215
      KLIPS on a Sparc 2 (101 KLIPS on a NeXT) and still uses a very small
      (41K) emulator. Comments and bug reports should be sent to
      binprolog@info.umoncton.ca. 

      
   CLP(R):

      CLP(R) is a constraint logic programming language with real-arithmetic
      constraints.  The implementation contains a built-in constraint solver
      which deals with linear arithmetic and contains a mechanism for delaying
      nonlinear constraints until they become linear.  Since CLP(R) subsumes
      PROLOG, the system is also usable as a general-purpose logic programming
      language.  It icnludes facilities for meta-programming with constraints.
      The system consists of a compiler, byte-code emulator, and constraint
      solver. CLP(R) is written entirely in C and runs on Suns, Vaxen,
      MIPS-based machines (Decstations, Silicon Graphics), IBM RS6000s and
      PS2s.  It is available free from IBM for academic and research purposes
      only. For more information, write to Joxan Jaffar, H1-D48, IBM Thomas J.
      Watson Research Center, P.O. Box 704, Yorktown Heights, NY 10598, or send
      email to joxan@watson.ibm.com or joxan@yktvmh.bitnet.


   Common ESP:

      Common ESP is an object-oriented system by the AI Language Research
      Institute. The binary is free for R & D use only -- send 1/4in CMT
      Sun3 and Sun4 (Sparc) with Sun OS R4.0.3, R4.1 or R4.1.1. For more
      information, write to AI Language Research Institute Ltd, Yoshitoku
      Bldg, Shiba 3-15-14, Minato-Ku, Tokyo 105, Japan, fax +81 3 3456 4418,
      or send email to k-hata@air.co.jp.


   cu-Prolog:

      cu-Prolog is an experimental constraint logic programming language
      available free from Japan's Institute for New Generation Computer
      Technology (ICOT). Unlike most conventional CLP systems, cu-Prolog
      allows user-defined predicates as constraints and is suitable for
      implementing a natural language processing system based on the
      unification-based grammar. For example, the cu-Prolog developers
      implemented a JPSG (Japanese Phrase Structure Grammar) parser in
      cu-Prolog with the JPSG Working Group (the chairman is Prof. GUNJI,
      Takao of Osaka University) at ICOT. cu-Prolog is a complete
      implementation of Constraint Unification (cu), hence the name.
      cu-Prolog is implemented in C for BSD UNIX 4.2/3. Professor Sirai of
      Chukyo-University has also implemented cu-Prolog for the Apple
      Macintosh and DJ's GPP (80386/486 MS-DOS machine with the DOS
      extender). cu-Prolog is available free by anonymous ftp from
      ftp.icot.or.jp. For further information, send email to ifs@icot.or.jp,
      or write to ICOT Free Software Desk, Institute for New Generation
      Computer Technology, 21st Floor, Mita Kokusai Bldg., 4-28, Mita
      1-chome, Minato-ku, Tokyo 108, Japan, fax +81-3-3456-1618.


   ESL Prolog-2 (PD Version):
      aisun1.ai.uga.edu:ai.prolog/eslpdpro.zip

      A prolog for MS-DOS systems with good performance. It deviates
      slightly from Edinburgh standard (strings "like this" are not lists
      of ASCII codes), but you can add a declaration that makes it fully 
      Edinburgh-compatible. It is a more limited version of the interpreter
      from the Commercial Version (see [3] below).

Subject: [4]  FTP Archives and Other Resources

The following are achives that contain Prolog-related material, such as
code, interpreters, articles, etc. Most of the archives are ftp sites.
They are listed by domain.name and [IP Address]. To access them and
download programs type at the prompt: 

	ftp <site name> (or IP address)
	login: "anonymous",
	password: your own return email address,
	cd <directory>, ls to see files, 
	set binary, 
	get <filename> to transfer file to your system
	stop with quit or exit

Deviations from this general scheme may occur but the above should
work in most cases.

      contents of the directory and CATALOGUE gives a (long!)
      description of each entry. Entries include the Logic Programming
      Tutor from Paine's book, the DEC-10 public-domain library, the
      Linger natural-language corrector, a simple object-oriented
      add-on for Prolog, graph utilities, among other things.

      Files in the archive are also available on MS-DOS floppies for a
      nominal fee to cover the cost of floppies, postage, and packing.  


   Machine Learning Algorithms Implemented in Prolog:

      In 1988 the Special Interest Group on Machine Learning of the German
      Society for Computer Science (GI e.V) decided to establish a library
      of PROLOG implementations of Machine Learning algorithms. The library
      includes PROLOG implementations of Winston's arch, Becker's AQ-PROLOG, 
      Fisher's COBWEB, Brazdil's generation of discriminations from derivation
      trees, Quinlan's ID3, inverse resolution, and Mitchell's version
      spaces algorithm. The programs are available via the anonymous
      ftp-server at the University of Osnabrueck:
         dione.rz.uni-osnabrueck.de:pub/unix/mlp  (131.173.128.15)

      Send additional PROLOG implementations of Machine Learning Algorithms
      to Thomas Hoppe, <hoppet@cs.tu-berlin.de>. Send suggestions and
      complaints about the ftp library to Werner Emde, University of
      Osnabrueck, <emde@gmdzi.gmd.de>.


   Prolog to SQL Compiler:

      The Prolog to SQL Compiler translates database access requests,
      which consist of a projection term and a database goal, to the
      appropriate SQL query. The compiler is written in standard Edinburgh
      Prolog and has been ported to a number of Prologs. The code posted to
      comp.lang.prolog works in ECRC's SEPIA Prolog, but should be easily
      ported to other Prologs. A detailed tech report on the implementation
      is available by email from draxler@sun1.cis.uni-muenchen.de (include
      your full postal address).  The compiler is copyright, but may be used
      free of charge for non-commercial purposes and redistributed provided
      the copyright notice is retained intact.

   XWIP: 
      export.lcs.mit.edu:/contrib/xwip.tar.Z
