CINA is a computer application in early development status. It's target is to simulate human conversations through speech analysis and interpretation using a semantic network. Today, such an application is called a "bot". CINA is built after the model of a human brain. For every different step and component of communication (like en-/decoding, analysis, interpretation, relationship) CINA uses an own module. The core and the components of CINA will be completly written in C++, later there will be a Qt user interface to make the interaction with the core application easier.
