PUMAS: Un Framework que Adapta la Información en Ambientes Ubicuos

Mobile Devices (MD) are characterized by intrinsic reduced capacities (e.g., size of screen, memory, data storage). PUMAS (Peer Ubiquitous Multi-Agent System) is a framework based on agents whose main objective is to provide nomadic users with information adapted to different criteria (their preferences, their location, etc.) when they access Web-based Information Systems (WIS) using such MD. PUMAS agents are organized in order to achieve an intelligent and adaptive information search. This search is on the one hand intelligent because is based on the knowledge of the agent (proper, acquired and inferred knowledge) and its capability of reasoning and, on the other hand, is adaptive because it takes into account the nomadic user’s profile, characteristics of her/his MD and ubiquitous context features (e.g., location, connection time, etc.). When a user searches for information through her/his MD, her/his queries are propagated through the agents of PUMAS (which add into these queries some characteristics of both the user and her/his MD for adaptation purposes) towards the Router Agent (which belongs to the 1 La autora Angela Carrillo Ramos cuenta con financiamiento parcial de la Universidad de los Andes
