One of my aims while creating Logos it was to implement mechanisms of co-operation between Logos and SPHINX AI software package, especially hybrid expert system shell as well as neural net Neuronix. The 1.0 version of Logos is able to generate knowledge base using syntax of PC-Shell knoweldge representation language. In this way it will be possible to use Logos eg. as a tool for V&V (validation and verification) process of PC-Shell knowledge bases without using CAKE system. The V&V function of Logos is simply much more advanced than that of CAKE so Logos can be useful for users of PC-Shell system in this process of V&V. The next step and in the next version it will be import of the PC-Shell knowledge bases. It is not so obviuos because the Logos is system using quite different architecture and built for other purposes than PC-Shell. So the first step to communicate between them has been done. It works.
