The paper discusses on context-based schema - the sensing, processing and actuating (SPA) architecture - for situation specific communication. In this paper, we apply the schema to bear communication research. The main idea of our research is to identify groups of voice sequences which are typical for certain situations such as waking up from hibernation, cubs coming out for the first time from the den, a female bear teaching her cubs, cubs playing, mating and defense of territory. The communication schema of a brown bear seems to be very goal-oriented and situation specific. Once we can identify context-dependent communication schemas, we will be able to better interpret bear vocalization. The bear communication ABC can be used by scientists, authorities, teachers, students, hikers and especially citizens living in bear-rich areas. For environmental conservation initiatives and programs, it is also important to interpret, early enough, weak signals coming from the bears' natural environments.
