Personalized recommender systems can be classified into three main categories: content-based, mostly used to make suggestions depending on the text of the web documents, collaborative filtering, that use ratings from many users to suggest a document or an action to a given user and hybrid solutions. In the col-laborative filtering task we can find(More)
– Electronic, web-based commerce enables and demands the application of intelligent methods to analyze information collected from consumer web sessions. We propose a method of increasing the granularity of the user session analysis by isolating useful subsessions within web page access sessions, where each subsession represents a frequently traversed path(More)
The number, variety and complexity of projects involving data mining or knowledge discovery in databases activities have increased just lately at such a pace that aspects related to their development process need to be standardized for results to be integrated, reused and interchanged in the future. Data mining projects are quickly becoming engineering(More)
Keywords: Ad Hoc networks management Ad hoc routing protocol MANET management a b s t r a c t This present research shows the creation of a model for the management of Ad Hoc mobile networks called HAMAN (High Availability Management Ad Hoc Networks). The HAMAN model has been struc-tured in layers in which each of the components and interfaces has been(More)
CRISP-DM is the standard to develop Data Mining projects. CRISP-DM proposes processes and tasks that you have to carry out to develop a Data Mining project. A task proposed by CRISP-DM is the cost estimation of the Data Mining project. In software development a lot of methods are described to estimate the costs of project development (SLIM, SEER-SEM, PRICES(More)
In this paper, we propose a three-phase methodology (measurement, calibration and estimation) for locating mobile stations (MS) in an indoor environment using wireless technology. Our solution is a fingerprint based positioning system that overcomes the problem of the relative effect of doors and walls on signal strength and is independent of network device(More)
In this paper we propose a flexible Multi-Agent Architecture together with a methodology for indoor location which allows us to locate any mobile station (MS) such as a Laptop, Smartphone, Tablet or a robotic system in an indoor environment using wireless technology. Our technology is complementary to the GPS location finder as it allows us to locate a(More)
