The world wide web has shift the way people get information and order services. However with the rapid development of the world wide web currently divided into web 1.0 to Web 3.0 or even web 4.0 the problem of searching and presenting information has also turned out: Finding the right piece of information is often a problem since searches are imprecise and often produce matches to many thousands of pages. Users face the task of reading the documents retrieved in order to extract the information desired. The construction of this prototype will approach customized navigation information systems to specific users domains this project is based on concepts of contextualization and geolocalization the contextualization is related with ontologies to describe a domain this ontology can be used to share information produced by people (collective learning) other relevant concepts related with this proposal are: Information overload paradox of distribution homogeneous information unit localization relative gravity. The main contribution of this project is to solve a problem and develop a useful tool related to the exploitation of the web. Project goals: define new algorithms that requires to use different methodologies from several research areas as ontologies and webminig in order to create a general purpose mobile application that retrieves and organizes information in a useful way to humans and computers. Develop an automated process that assists users to contextualize-them using mobile devices. Make a contribution with new methodologies applying them in a intermediate step between the first generation of the web and the semantic web. Other relevant concepts are: Intelligent searches: during the last two years that we worked developing several prototypes one of the most interesting findings are Intelligent Searches that means: exact results related and recommend results based on the structure of semantics of the ontology (subject predicate and object). Information overload: information overload that refers to the difficulty a users can have understanding an issue and making decisions that can be caused by the presence of too much information. Paradox of distribution: Information are distributed but user needs of this information are local this means that who needs a unit of information probably will depend on its context. Collective Learning: The use of ontologies facilitate knowledge sharing and reuse this will generate learning between teams organizations communities and societies. Homogeneous information unit: The information units need to be homogeneous to be processed and analyzed by humans. Localization Related: to the place that some user are located (i.e. geolocatization) this location will give a context to the user this context will be related with a need that will be satisfied from a several possibilities (e.g. food shelter product entertainment etc.) Relative gravity: This concept is related with some spaces has a relative gravity depending on the interest or importance of many users.
