Identifying, Categorizing, and Analysing Sample Clauses

Identifying, Categorizing, and Analysing. Social Relations for Trust Evalua- tion‌ As we have seen above, more expressive reputation valuations may be achieved if the relationship between the agent in question and its recommending agent is considered. This is opposed to tradi- tional techniques that assume that recommending agents are fully trusted. Xxxxx et al. [10] propose a method for dynamically identifying these relationships, categorizing them, and analysing them. In this model, agents are defined as ‘entities described by a set of attributes’. Attributes are features of the environment, and agents are capable of performing actions by adding or removing these attributes. Agents also pursue goals, which are achieved by performing actions. Agent ac- tions are divided into sensor capabilities, which retrieve the values of the environment’s attributes, and actuator capabilities, which change the environment’s attributes. Attributes that may be ma- nipulated by an agent are defined as the agent’s region of influence (RoI). Those that may be sensed by an agent are defined as the agent’s viewable environment (VE). As a result, goals are di- vided into query goals that require an agent to perform a sensory action that lies within the agent’s VE, and achievement goals that require an agent to perform an actuating action that lies within the agent’s RoI. According to this model, relationships between agents may then be identified by studying how their VEs and XxXx overlap. Relationships may then be characterized into several types, depending on the context. The relationship types illustrated by Xxxxx et al. [10] lie in the context of an e-commerce scenario. First, two agents are said to be in a trade relationship if the goal of agent a is to sell a product that agent b may or may not wish to acquire. Second, one agent may be dependent on another, for instance, if agent a is selling a product that agent b wishes to buy. The intensity of the relationship depends on several factors, such as the number of sellers, the abundancy of the product, etc. This intensity basically determines who is dependent on whom and to what extent is it dependent on the other. In this case, the goal of the depending agent lies in the other agent’s RoI; moreover, the other agent’s RoI lies in the intersection of both agents’ VEs. Third, two agents may be in a competitive relationship, for instance, if both are selling the same products. Again, the intensity of this relationship may depend on several factors, such as the price ...
