To execute LDA_WEKA.jar it is necessary to open a command console and go to the same location as the file. The second possibility is to execute the file with a JAR extension with a command directly from a console, and finally it can be executed by double clicking directly on the executable file with an EXE extension. The first is to import the project where the source code is located in some IDE with support for Java projects and ANT, compile and run the project. To execute this project there are several possibilities. Once installed the plugin will appear in the list below.jar package from our filesystem through the File/URL button.
