This paper describes our preliminary analysis on the induction of communication protocols. Our work has two goals: (i) to recognize rules (i.e. protocols) from the communicative behavior of people in daily activities and; (ii) to understand how a person learns to infer communication protocols. Our research aim is to conceive an effective Autonomous Agent and Human Agent communication. We record sequences of communication exchanges of computer scientists collaborating online as a benchmark for the analysis of regularities that emerge from the exchanges of those communications. We analyze their conversation structures and interaction. We found a particular event where person A had applied a similar manner of communicating as person B did in a similar situation (learning rules as a side effect of communicating). We demonstrate this analysis.
