Recommendation System based on user interaction data applied to intelligent electronic books

Nowadays, new technologies and the fast growth of the Internet have made access to information easier for all kind of people, raising new challenges to education when using Internet as a medium. One of the best examples is how to guide students in their learning processes. The need to look for guidance from their teachers or other companions that many Internet users experience when endeavoring to choose their readings, exercises o practices is a very common reality. In order to cater for this need many different information and recommendation strategies have been developed. Recommendation Systems is one of these. Recommendation Systems try to help the user, presenting him those objects he could be more interested in, based on his known preferences or on those of other users with similar characteristics. This document tries to present the current situation with regards to Recommendation Systems and their application on distance education over the Internet.

Extensible architecture for context-aware mobile web applications

Highlights? We develop a context-aware web application. ? We present a new approach for developing context-aware web applications for mobile phones. ? Use context information in web applications to add new features that were not possible before. ? Use context information in web applications can improve usability. ? Include context information in web applications using a small group of specific XML tags. Over the years web browsers have gone from being used only on personal computers to a wide range of devices such as music players, video game consoles and mobile phones. Today people commonly use native applications and web applications on their mobile phones. There are many technical differences between native applications and web applications. One of these differences is that native applications can use the device hardware components that capture and manage context information, such as GPS, sensors, camera, etc. The differences between mobile phones require that in most cases it is necessary to develop a native application for each specific platform (iOS, Android, WebOS, Windows Phone, Symbian, etc), which is really expensive, so many developers and companies choose to develop web applications that can be used on any device with a web browser. The use of context information has proved very useful in many native applications, but web applications cannot use this type of information. This paper describes a proposal that allows web applications to access context information in a simple and fast. The proposed system consists of a modular web browser context aware and a set of specific XML tags that can be used on web applications.

Using extended web technologies to develop Bluetooth multi-platform mobile applications for interact with smart things

Nowadays the classic web paradigms are being subjected to changes; every day millions of users around the world use their Smartphones to access web applications from anywhere. The World Wide Web it is one of the biggest repositories of information in the world, and that information is stored in internet servers and repositories, but today in the real world there are many other information sources such as electronic devices with communication capabilities: smart appliances and sensor networks. The Smartphones are equipped with communication hardware elements like the Bluetooth module, which allows the Smartphone to exchange information with nearby electronic devices. Every day more and more mobile applications are being developed for native platforms that use Bluetooths communication module to send and receive information from different sources. Native mobile applications use the specific platforms APIs to manage the Bluetooth communication actions (send and receive information, search for devices, etc.), however, web applications do not have technical capabilities to manage the Smartphones Bluetooth communication module and thereof cannot use that kind of information. The main objective of this research work is to design a novel framework that allows classic web applications to use information from nearby electronic devices. The proposed framework must be easy to use and able to be integrated with common web technologies. Developers can use this framework to include new information sources and data exchange procedures in an easy way. The new type of information can be merged with the web to develop or improve algorithms and web applications.

Dynamic, ecological, accessible and 3D Virtual Worlds-based Libraries using OpenSim and Sloodle along with mobile location and NFC for checking in

It also proposes their application to the creation of open libraries to share and disseminate the new dynamic nature of knowledge, in the understanding that 3D virtual worlds may contribute to the future of libraries as part of green initiatives to achieve an ecologic and sustainable planet.

Use of ARIMA mathematical analysis to model the implementation of expert system courses by means of free software OpenSim and Sloodle platforms in virtual university campuses

Abstract This paper describes the implementation of a virtual World based in GNU OpenSimulator. This program offers a great variety of Web 3.0 ways of work, as it makes possible to visit web sites using avatars created for that purpose. The Universities should be familiar with the creation of new metaverses. That is the reason why a new basic methodology for the creation of a course on expert systems within a metaverse in a virtual campus for e-learning. Besides the creation of a repository or island, it is necessary to make measurements of the performance of the server dedicated to host the system when the number of users of the application grows. In order to forecast the behavior of such servers, ARIMA based time series are used. The auto-correlogrames obtained are analyzed to formulate a statistical model, as close to reality as possible.

Metamodel for integration of Internet of Things, Social Networks, the Cloud and Industry 4.0

Internet of Things (IoT) is changing the world. Software for manufacturing industry is perceived as the new industrial revolution. It is creating new opportunities for both the economies and the society. Deployment of Internet of Things for development of Industry 4.0 changes processes and manufacturing systems while it also changes players in a wide variety of types and shapes. In that sort of systems, information is related to manufacturing status, trends in energy consumption by machinery, movement of materials, customer orders, supply data and all data related to smart devices deployed in the processes. This paper analyzes Internet of Things (IoT), its use into manufacturing industry, its foundation principles, available elements and technologies for the man-things-software communication already developed in this area. And it proves how important its deployment is. Describes a proposal of architecture of the Internet of things applied to the industry, a metamodel of integration (Internet of Things, Social Networks, Cloud and Industry 4.0) for generation of applications for the Industry 4.0, and the manufacturing monitoring prototype implemented with the Raspberry Pi microcomputer, a cloud storage server and a mobile device for controlling an online production process.

TALISMAN MDE Framework: An Architecture for Intelligent Model-Driven Engineering

Models are becoming first-class artifacts in Software Engineering because they provide better productivity and quality. In this paper we present a framework for developing all kinds of applications, mainly by following the best practices of the two main approaches to Model-Driven Engineering (MDE). On one hand is MDA (Model-Driven Architecture), proposed by the OMG (Object Management Group) and on the other hand are the Software Factories, proposed by Microsoft. Both approaches have their pros and cons and that is why we want to mix them into a single framework by selecting the best that each of them can give us. TALISMAN MDE Framework is based on the opinion of recognized experts in MDE and on the lessons learned in our previous work, TALISMAN MDA.

Method for analysing the user experience in MOOC platforms

MOOCs have recently become very popular, since some of these massive online courses can reach thousand students. Faculty members from top universities deliver courses through MOOC platforms: Coursera, Edx, Miriada X, etc. Apart from the content, many other factors can influence the quality of a course; for instance, a bad user experience of a Web MOOC platform can lead students to drop out an interesting and well-organised course. MOOC platforms require much effort to care for the user experience. This research aims to develop a specific method for evaluating the user experience of MOOC platforms. The method is based on the general principles of Web user experience and highlights the aspects influencing MOOCs. The system proposed in this paper calculates a quantifiable index, useful for comparing different MOOC platforms, quantifying the quality evolution of the user experience, and promoting further studies so as to determine the impact of the user experience on students: satisfaction in surveys, enrollment figures, dropout rates, among others.

Patterns of Software Development Process

This article presents a set of patterns that can be found to perform best practices in software processes that are directly related to the problem of implementing the activities of the process, the roles involved, the knowledge generated and the inputs and outputs belonging to the process. In this work, a definition of the architecture is encouraged by using different recurrent configurations that strengthen the process and yield efficient results for the development of a software project. The patterns presented constitute a catalog, which serves as a vocabulary for communication among project participants (1), (2), and also can be implemented through software tools, thus facilitating patterns implementation (3). Additionally, a tool that can be obtained under GPL (General Public license) is provided for this purpose.
