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.

Disclaimer:

   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 <[e-mail]>. The Prolog FAQ and this
Prolog Resource Guide are intended to complement one another.

The draft ISO standard for Prolog is available by anonymous ftp from
aisun1.ai.uga.edu in the directory ai.prolog.standard.

----------------------------------------------------------------
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
      <[e-mail]>.


   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
      [e-mail].


   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. Includes MS-DOS support. 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
      [e-mail] or [e-mail].

   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 [phone],
      or send email to [e-mail].


   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 [e-mail],
      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 [phone].


   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).

   IC Prolog:
      doc.ic.ac.uk:/pub/languages/icprolog/pd-ICP-<VERSION>.tar.Z
      src.doc.ic.ac.uk:/computing/programming/languages/prolog/icprolog/.
      Runs on Sun3, Sun4. There is MacProlog source in a further subdirectory.

      Produced by Imperial College, IC Prolog includes multi-threading,
      parlog, TCP primitives, communication primitives, and "mailboxes", a
      high level communication system.  Includes the preprocessor for the
      prolog language extension L&O from the book "Logic & Objects".

      See also Yannis Cosmadopoulos and Damian Chu, "IC Prolog ][: a
      Language for Implementing Multi-Agent Systems", in Tutorial and
      Workshop on Cooperating Knowledge Based Systems, September 23-25,
      1992, Keele University. A copy of this paper may be found ing
      laotzu.doc.ic.ac.uk [146.169.21.1] as /pub/icp-paper.ps.Z, or on
      src.doc.ic.ac.uk [146.169.2.1] in the directory
      /computing/programming/languages/prolog/icprolog/

      Contact Damian Chu <[e-mail]> for questions about IC
      Prolog, and contact Zacharias Bobolakis <[e-mail]> for
      information about L&O.


   Lolli:

      Lolli is an interpreter for logic programming based on linear logic
      principles. Lolli, named for the linear logic implication operator
      "-o" called lollipop, is a full implementation of the language
      described in the paper "Logic Programming in a Fragment of
      Intuitionistic Linear Logic" (Josh Hodas & Dale Miller, to appear in
      Information and Computation), though it differs a bit in syntax, and
      has several built-in extra-logical predicates and operators.  To
      retrieve a copy of the Lolli system, ftp (anonymously) to
      ftp.cis.upenn.edu and retrieve the file pub/Lolli/Lolli-07.tar.Z. This
      distribution includes full ML source, along with a Makefile, as well
      as several background papers and a collection of example programs. For
      those who do not have SML-NJ at their site, the authors hope to
      provide pre-built binaries for a variety of architectures. These
      binaries can be found on ftp.cis.upenn.edu in the directory
      pub/Lolli/binaries. At present Sparc and NeXT binaries are available.
      If you compile lolli on a new architecture, please contact Josh Hodas
      at <[e-mail]> so that he can make your binary
      available.

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.

      The BiBTeX bibliographies are available in /pub/lp-proceedings.


   Prolog Repository:

      Established by Jocelyn Paine of Experimental Psychology, Oxford
      University in 1987. The current catalogue (January 1991) contains
      30 entries. For catalogue, queries and contributions contact POPX at:
         [e-mail] (internet) or
         [e-mail] (janet)

      FTP access is available through the Imperial College archive at
         src.doc.ic.ac.uk  (146.169.2.1)
      in the directory
         computing/programming/languages/prolog/pd-software
      with a short-cut link of:
         packages/prolog-pd-software
      To access it, cd to either of the above directories via
      anonymous ftp. The file README gives a brief summary of the
      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, <[e-mail]>. Send suggestions and
      complaints about the ftp library to Werner Emde, University of
      Osnabrueck, <[e-mail]>.


   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 [e-mail] (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.

   PSI:

      PSI is a handy system for the management and retrieval of your
      personal data, be it addresses, CD collections, or bibliographic
      references. It is intended for the non-commercial user. It may not be
      as full-fledged as some data-base systems, but has some features that
      you won't find in most commercial systems. Also, you may find it
      easier to set up and faster to use. PSI is useful for a broad range of
      data. Indexing with descriptors makes searching for the data you need
      fast, and the interface to other data-base formats (import and export)
      is quite powerful.  PSI was written in LPA MacProlog and is a "genuine
      'double clickable' Mac application". PSI runs on all Macs with System
      6 or 7 in 1MB of main memory. As LPA MacProlog isn't yet 32-bit clean,
      PSI isn't either. Extensive documentation and some examples are
      included.  PSI is available by anonymous ftp from
      sumex-aim.stanford.edu, directory info-mac/app, file psi-23.hqx. It
      was also available on a recent Nautilus CD-ROM and will be on the
      first Info-Mac CD-ROM.

   XWIP:
      export.lcs.mit.edu:/contrib/xwip.tar.Z
      ftp.uu.net:X/contrib/xwip.tar.Z

      XWIP is an X Windows interface for PROLOG.

Subject: [7]  The Prolog 1000 Database

The Prolog 1000 is a database of real Prolog applications being
assembled in conjunction with the Association for Logic Programming
(ALP) and PVG. The aim is to demonstrate how Prolog is being used in
the real world and it already contains over 400 programs with well
over 2 million lines of code. The database will be published in due
course and available for research use. If you have or know about a
program that might qualify for inclusion, send an email message to Al
Roth ([e-mail]) for an electronic entry form which
only takes a few minutes to complete. Or write to Prolog 1000, PO Box
137, Blackpool, Lancashire, FY2 0XY, U.K., Fax: [phone]
Telephone: [phone]. (Floppy disks for PC or Mac in text form are
also welcome, and paper entries may also be sent).  Queries may also
be addressed to: Chris Moss ([e-mail]), Leon Sterling
([e-mail]).
