Project ======= KeplerWeka represents a machine learning module for the scientific workflow engine Kepler (http://www.kepler-project.org/). It uses the WEKA machine learning workbench (http://www.cs.waikato.ac.nz/ml/weka/) for all the machine learning tasks it offers. Homepage: http://keplerweka.sourceforge.net/ License ======= KeplerWeka is released under the GNU General Public License 2. See module-info/COPYING for details on the license. Installation ============ 0 General In order to get KeplerWeka running, you need to modify your Kepler installation or source tree. It is recommended to backup your current Kepler before proceeding with the installation of KeplerWeka. 1 KeplerWeka 1.1 Installation using KeplerWeka release Previously installed versions of KeplerWeka should be removed first, of course. Deleting the "keplerweka" sub-directory in the Kepler installation directory should be sufficient for that. In order to install KeplerWeka, simply decompress the ZIP archive into your Kepler installation directory. NB this will overwrite any currently active suite. 1.2 Installation from source code The following sections cover the various steps that you need to perform in order to get KeplerWeka installed using source code obtain from a source archive or from subversion directly. 1.2.1 KeplerWeka Suite If you are using a source archive, simply decompress it into your Kepler source tree directory. Otherwise, if you are obtaining the source code directly from subversion, run the following command in your Kepler source tree: svn co https://keplerweka.svn.sourceforge.net/svnroot/keplerweka/trunk keplerweka The suite is built using the provided ant build file (tested only under Linux). Issue the following command from within the "keplerweka" module directory: ant 1.2.2 Ontologies KeplerWeka extends the Kepler ontologies a bit, making it easier to find the actors. Minor changes to a Kepler configuration file are necessary. Copy the following files: keplerweka/resources/configurations/ontologies/KeplerWeka-project.owl keplerweka/resources/configurations/ontologies/KeplerWekaActorOntology.owl Into the following directory: common/configs/ptolemy/configs/kepler/ontologies Edit the following file: common/configs/ptolemy/configs/kepler/ontologies/ontology_catalog.xml And add the content of the following file to it (inside the <ontologies>...</ontologies> tags): keplerweka/resources/configurations/ontologies/ontology_catalog.xml.addon 1.2.3 Icons In order to display KeplerWeka's custom icons, you need to updated some Kepler configuration files, unfortunately. KeplerWeka is fully functional without the icons, but the actors will be easier to distinguish with their proper icons installed. Add the content of: keplerweka/resources/configurations/uiSVGIconMappingsByClass.xml.addon to the following Kepler configuration file (inside the <config>...</config> tags): gui/resources/configurations/uiSVGIconMappingsByClass.xml 2. WEKA The weka.jar library in the lib/jar directory can be replaced with any WEKA jar of the developer version that is later than revision 6896 (>= 3.7.3). Packages that were installed through WEKA's package manager, are accessible in KeplerWeka as well. The partialLeastSquares package is already available in the lib/jar directory, as the setup generator uses the PLS filter in its default setup. 3. Eclipse If you obtained the source code of KeplerWeka, then you can include it in your Kepler Eclipse environment. First, copy the file ".classpath.default" to ".classpath". Then, you can import the project in Eclipse. $Revision: 197 $
