The WoM simulation aims at showing agglomerations of users in few web sites and at studying the different factors that lead to such a macro-structure. The paper focuses on the architecture of the multi-agent simulation environment. In this environment, a simulation application is constructed using four different components categories, namely: agent collections, a worker, a communication channels component, and a control component. An agent collection can be constructed from different kinds of Small World graph components. Small World graphs are used to represent the social network and web sites links. An agent collection scales to hundreds of thousands of agents. A worker component is configured from a set of behavior components to implement the behavior of agent collections. Simulation input/output is monitored through a communication channel component. The control component is responsible for configuration and initialization of the application components. The control component, also, invokes the worker at each simulation time step. For scalability, the environment architecture is designed to be suitable for distribution and parallelization.

Of course, such a geographic proximity with input providers and consumers, would at first reduce transportation costs. But why cities, information cities, i.e. large agglomerations of people and economic activity emerge in the virtual world? In the Internet, transportation costs are zero. Web sites can easily be reached from anybody and everywhere with no particular cost. In these conditions of equal access distance, one would rather expect a smooth web geography with a relatively even distribution of visitors per site. However, the web economy illustrates strong agglomeration trends with a very small number of web sites capturing a large segment of the web population and the most of virtual economic activity. This paper attempts to provide a sound basis for the dynamics of population concentration in the web under increasing returns.

They will provideIn the coming years, we expect many kinds of medium and large-scale information sites to emerge over the Internet, which will represent or mimic small and large "physical" cities. They will provide local and global information and services to registered inhabitants. Just like physical cities, these "information cities" (iCities) will house "infohabitants" who will participate in activities such as navigating the city, performing commercial transactions, socializing, and collaborating. We are already witnessing the emergence of large-scale web portals providing local information about cities, access to local government services, community services and a place for businesses to advertise and attract consumers on-line. In this paper, we present a taxonomy of information cities
