3.1.1.4 Collective mind

The Collective Mind manages expectation networks that are socially built. These expectations arise because the agents look forward to certain behaviors from other agents, as well as the knowledge found in the agents themselves that their actions can also be part of the expectations of the other agents. The Collective Mind also makes abstractions, generalizations and schemes from the individual expectations, taking control of the emergent process of a current context shared representation (dos Santos França, 2010).

### **3.1.2 Person agent architecture**

The Person agent portrays an individual that will have a behavior related to the collective panic situation. Such behavior is directed by the Symbolic Interactionism and Norm Emergent theories described in Section 2.1.3. An overview of the agent's architecture can be found in Figure 6.

Fig. 6. General Overview of the Person Agent.

The Person agent is made of four modules: Reception and Data Gathering Module, Hybrid Belief-Knowledge Management Module, Social-Cognitive Module and Message Sender Module.

### 3.1.2.1 Reception and Data Gathering Module

The main function of the Reception and Data Gathering Module (RDGM) is listening to the environment, gathering relevant information, establishing the nature of such information and storing it in the Information Storage. This module has two cores: the Data Selector that scans data for the creation of a current situation portrayal, and the Information Analyzer that checks the information integrity in terms of syntax and semantics and passes the information to the correct information base: Knowledge Base of Belief Base. Physical information is always treated as knowledge and information provided by other agents is accepted as a belief until it is confirmed. The Social-Cognitive Module can also request data gathering on the environment if the agent needs some information from the other agents (dos Santos França, 2010).
