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)
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)
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)
– 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)
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)
Based on rough set theory many algorithms for rules extraction from data have been proposed. Decision rules can be obtained directly from a database. Some condition values may be unnecessary in a decision rule produced directly from the database. Such values can then be eliminated to create a more comprehensi-ble (minimal) rule. Most of the algorithms that(More)
Nowadays, humans and machines don't use the same format of knowledge representation. This gap represents a serious problem in the interaction human-machine. More specifically, comprehension of text and images plays a key role in the process underlying Web navigation. This fact aim us to explode the application of intelligent methods that minimize the gap(More)
