library(race)

Prolog client for the SOAP interface of the Attempto Reasoner RACE.

Installation

This package requires library(wsdl). It can be installed from within SWI-Prolog using the following command:

?- pack_install(wsdl).

Then, you can install this package by calling:

?- pack_install('https://github.com/fnogatz/race.git').

As of now, this package has not been published in SWI-Prolog's packs list, so pack_install(race) is not yet supported.

Example Usage

First of all you have to load the library:

?- use_module(library(race)).

Consistency Check

%% check_consistency(+Knowledge)
?- check_consistency("John is great. He is not great.").
false.

%% check_consistency(+Knowledge, -Inconsistencies)
?- check_consistency("John is tall. Mary is tall. John is not tall.", Inconsistencies).
Inconsistencies = [fact("John is tall."), fact("John is not tall.")].

Question Answering

%% ask(+Knowledge, +Question, -Result)
%% ask(+Knowledge, +Question, -Result, +Options)
?- ask("Every man is a human. John is a man.", "Who is a human?", Result).
Result = results([
   proof([
      fact("Every man is a human."),
      fact("John is a man."),
      substitution("who", "John")
   ]),
   proof([
      fact("Every man is a human."),
      fact("John is a man."),
      substitution("who", "(at least 1) man")
   ])
]).

By using the option sentence(true), it will return a textual response instead. It can be used in sentences like this can be answered with ...:

?- ask("Every man is a human. John is a man.", "Who is a human?", Result, [sentence(true)]).
Result = results([
   "who as John and the known fact that Every man is a human and the known fact that John is a man",
   "who as (at least 1) man and the known fact that Every man is a human and the known fact that John is a man"
]).

Theorem Proving

%% prove(+Knowledge, +Theorem, -Result)
%% prove(+Knowledge, +Theorem, -Result, +Options)
?- prove("John likes Mary. If A likes B then B likes A.", "Mary likes John.", Result).
Result = results([
   proof([
      fact("John likes Mary."),
      fact("If A likes B then B likes A."),
      substitution("something", "John"),
      substitution("something", "Mary")
   ])
]).

Use sentence(true) in Options to get a textual response instead. It can be used in sentences like this can be proven with ...:

?- prove("John likes Mary. If A likes B then B likes A.", "Mary likes John.", Result, [sentence(true)]).
Result = results([
   "something as John and something as Mary and the known fact that John likes Mary and the known fact that If A likes B then B likes A"
]).

Background

This package uses the SOAP interface of the RACE web service. A detailed specification is available online as part of the RACE web service. We make use of the provided WSDL file with some modifications in order to be compatible with SWI-Prolog's library(wsdl). The adapted and original version of the WSDL file can be found in the `/prolog/race/wsdl` directory.
