An approach to social system simulation based on information fusion

We focus on human information processing characterized by information fusion, and propose a new simulation method for a social system. We consider the role of custom and language in human intelligence, and apply it to information processing. We use natural language as a tool for information fusion by a computer. In this context we discuss a simulation model imitating the human thinking process. As an example, we build a model to estimate the future trends of foreign exchange rates.
