This section describes the usage of jPLSA in command line or terminal, using a pre-compiled file named jPLSA.jar. Here, it is supposed that Java is already set to run in command line or terminal (e.g. adding Java to the environment variable path in Windows OS).
Users can find the pre-compiled file jPLSA.jar and source codes in folders jar and src, respectively. The users can recompile the source codes by simply running ant (it is also expected that ant is already installed).
File format of input corpus: Similar to file corpus.txt in the data folder, jPLSA assumes that each line in the input corpus represents a document. Here, a document is a sequence of words/tokens separated by white space characters.
Now, we can train PLSA/PLSI by executing:
$ java -jar jar/jPLSA.jar -corpus <PATH-TO-CORPUS> -ntopics <NUMBER-OF-TOPICS> -niters <NUMBER-OF-ITERATIONS> -name <EXPERIMENT-NAME>
Example:
$ java -jar jar/jPLSA.jar -corpus data/corpus.txt -ntopics 20 -niters 1000 -name test
