This software and its documentation is distributed under the terms of the FSF Lesser GNU Public License (see LICESNE for details). This program comes with ABSOLUTELY NO WARRANTY; This is free software, and you are welcome to redistribute it under certain conditions; for details type: java -jar spindle-<version>.jar --license This release of SPINdle requires JDK 1.6 (or above). =========== Description ----------- This software, written in Java, implements reasoner to compute the consequence of theories in defeasible logic. The implementation covers both basic defeasible logic and modal defeasible logic. In version 1.x.x, the inference process for basic defeasible logic is implemented based on the algorithm proposed by Maher and the reasoner for modal defeasible logics implements the algorithms of Governatori & Rotolo; while in version 2.x.x, the implementations (for both SDL and MDL) are based on the new reasoning algorithm as described in Lam & Governatori . The different of approaches used in version 1.x.x and 2.x.x is due to the fact that, in Maher's approach, the support of literals under superiority relations cannot be blocked after the superiority removal transformation. That is, in situations where an inferior rule was defeated by a superior rule, the support of the inferior rule still exist which subsequently affecting the conclusions being derived. However, in version 2.x.x, this problem is resolved since the new approach that we devised did not require the removal of superiority relations, and can preserve all the representational properties of the defeasible theories. ============= Using SPINdle ------------- To use SPINdle, type: java -jar spindle-<version>.jar [--options] [file1 | dir1] [file2 | dir2] ... where options include: --version show software version --license show software license --console run in console mode --log.level log level (ALL,INFO,FINE,FINEST,etc) --app.showProgress is show reasoning progress --app.showProgress.timeInterval show progress time interval --app.saveResult is save conclusions --app.result.folder folder for storing conclusions --reasoner.version reasoner version to be used --reasoner.logInference log rule status while reasoning --reasoner.ambiguityPropagation ambiguity propagation support --reasoner.wellFoundedSemantics well-founded semantics support ==================== Building from source -------------------- The SPINdle build system is based on Jakarta Ant, and is rely on a build file written in XML as building instructions. For more information please refer to "http://ant.apache.org". If everything is right, you can type: ant dist to compile the source code and archive it as an executable jar file. 2. Build targets The build system is not responsible for compiling SPINdle into a jar file, but also responsible for creating JavaDoc documentations and other tasks, such as: compile - compiles the source code (ONLY). dist - compile the source code and archive it as an executable jar file. run - run the reasoner. javadoc - generates the API documentation in ./docs/api. clean - restore the distribution to its original and clean state. For example, to build the samples, type: ant compile To generate the API documentation, type: ant javadoc To learn the details of what each target does, please read the build.xml file. ======= Contact ------- Author: H.-P.
