Java Based AIML Interpreters

Hi, I am doing my research project, my research is about Education on MUVE engines and mainly to implement a chatbot concept, currently I am reseraching about all the java based AIML interpreters, and analysed all the existing java based interpreters such as “ProgramD/W”, “Charliebot” and “Chatterbean”, I am not able to get relevant source for any interpreters, mainly i am looking for ProgramD related research papers to study more on this interpreter, i would be very thankful if you could please advice me on available research sources.

Would it be possible or allowed to use ProgramD to develop a Chatbot on MUVE ?, and thought of asking your advice on this subject since my area of research is involved in this topic, i would be very thankful if you could please guide me in some parts of achieving chatterbot using good interpreter.

Thanks
Nick

Well, Program D seems to be free and open source, so I'm sure you could use it in some way. Have you already checked their wiki at http://aitools.org/Program_D ?
