The aim of this project is the development and implementation of a web framework which allows the creation and simulation of social networks in order to analyse the diffusion of hearsay in accordance to the relationship between the different types of users. With this purpose, a web framework has been developed capable of generating networks from an initial number of nodes inserted by the user, a possibility of creating an own network inserting each node and its relationship with each other or loading a network created previously. The generated network, can be saved for future simulations. A behaviour will be assigned to each agent (users of the network) depending on the number of its relations with the others agents. As last functionality, the user can download the red in a GEXF (Graph Exchange XML Format) file in order to process it with a SNA software. A last functionality added to the project is the possibility of download the code in order to extend the behaviour of the agents to adapt it to the user’s needs. This report presents the build-up of the framework piecemeal and subsequent connection between them in order to shape the final framework. An analysis of the different tools used and why they are chosen or not is included too. Finally, some appendixes are included to extend some aspects and facilitate the understanding of these, and some tutorials to provide the needed information to maintain and develop future improvements.
