Knowledge Representation and Reasoning Tools

Overview

The KR library is for working with knowledge representations and knowledge bases. Currently it facilitates use of RDF-based representations backed by triple-/quad- stores. It provides a consistent clojure based way of interacting with its backing implementations, which currently include the Jena and Sesame APIs.

Basic Use

The primary api functions you're likely to use come from the kr-core apis:

(use 'edu.ucdenver.ccp.kr.kb)
(use 'edu.ucdenver.ccp.kr.rdf)
(use 'edu.ucdenver.ccp.kr.sparql)

To actually get a KB instance to work with you'll need to make sure the implementation-specific code is loaded:

(require 'edu.ucdenver.ccp.kr.sesame.kb)

OR

(require 'edu.ucdenver.ccp.kr.jena.kb)

The examples also provide details on how to interact with a KB (to appear).

More detailed uses can be found in the test cases for both the KB, RDF, and SPARQL APIs. They are here: https://github.com/drlivingston/kr/tree/master/kr-core/src/test/clojure/edu/ucdenver/ccp/test/kr

Maven

releases are deployed to clojars:

<repository>
  <id>clojars.org</id>
  <url>http://clojars.org/repo</url>
</repository>

the core dependency is kr-core:

<dependency>
  <groupId>edu.ucdenver.ccp</groupId>
  <artifactId>kr-core</artifactId>
  <version>1.4.0</version>
</dependency>

but the core dependency is unnecessary if you are brining in either the sesame or jena implementations:

<dependency>
  <groupId>edu.ucdenver.ccp</groupId>
  <artifactId>kr-sesame-core</artifactId>
  <version>1.4.0</version>
</dependency>

<dependency>
  <groupId>edu.ucdenver.ccp</groupId>
  <artifactId>kr-jena-core</artifactId>
  <version>1.4.0</version>
</dependency>
