Implicit feedback techniques on recommender systems applied to electronic books

The goal of this research is to define and capture a series of parameters that allowed us to perform a comparative analysis and find correlations between explicit and implicit feedback on recommender systems. Most of these systems require explicit actions from the users, such as rating, and commenting. In the context of electronic books this interaction may alter the patterns of reading and understanding of the users, as they are asked to stop reading and rate the content. By simulating the behavior of an electronic book reader we have improved the feedback process, by implicitly capturing, measuring, and classifying the information needed to discover user interests. In these times of information overload, we can now develop recommender systems that are mostly based on the users behavior, by relying on the obtained results.

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.

SBPMN - An easier business process modeling notation for business users

At the moment the notations for the modeling of business process is based in technical aspects. Therefore most notations are not understood by the business users due to the complexity of them. In this paper we present a notation that allows business users to model their business process. For this reason the notation must be agile, easy to learn and design, and capable to provide semantic information about the process. With the objective of demonstrating the characteristics of the proposal notation in this paper we make a research to compare and evaluate the usability of the notation with the standard notation more extended, BPMN.

Modeling architecture for collaborative virtual objects based on services

With technological advances there are many physical objects that are designed in digital format, some examples are: books, agendas, tickets, etc. One of the characteristics of digital objects is that each type of object has its own format, in most cases each object type can only be interpreted by a particular application, so will have problems to be interpreted. Internet of things (IoT) promotes the integration and communication between physical objects, including digital objects on the IoT can automate and streamline many tasks. The absence of common format for digital objects also causes problems of interaction and communication. There is no standardized way to obtain the actions or services associated with the digital object, which makes it difficult for these digital objects to interact and integrate in a generic way with other applications, devices or embedded systems. Based on the problems identified in this document a proposal is detailed in search for a single structure and for the construction of any digital object. The validity of the approach has been verified through a prototype system working with real appliances.

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.

WESONet: Applying semantic web technologies and collaborative tagging to multimedia web information systems

The publication of different media types, like images, audio and video in the World Wide Web is getting more importance each day. However, searching and locating content in multimedia sites is challenging. In this paper, we propose a platform for the development of multimedia web information systems. Our approach is based on the combination between semantic web technologies and collaborative tagging. Producers can add meta-data to multimedia content associating it with different domain-specific ontologies. At the same time, users can tag the content in a collaborative way. The proposed system uses a search engine that combines both kinds of meta-data to locate the desired content. It will also provide browsing capabilities through the ontology concepts and the developed tags.

A review about Smart Objects, Sensors, and Actuators

Smart Objects and the Internet of Things are two ideas which describe the future, walk together, and complement each other. Thus, the interconnection among objects can make them more intelligent or expand their intelligence to unsuspected limits. This could be achieved with a new network that interconnects each object around the world. However, to achieve this goal, the objects need a network that supports heterogeneous and ubiquitous objects, a network where exists more traffic among objects than among humans, but supporting for both types. For these reasons, both concepts are very close. Cities, houses, cars, machines, or any another object that can sense, respond, work, or make easier the lives of their owner. This is a part of the future, an immediate future. Notwithstanding, first of all, there are to resolve a series of problems. The most important problem is the heterogeneity of objects. This article is going to show a theoretical frame and the related work about Smart Object. The article will explain what are Smart Objects, doing emphasis in their difference with Not- Smart Objects. After, we will present one of the different object classification system, in our opinion, the most complete.

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.

TALISMAN MDE: Mixing MDE principles

The Model-Driven Engineering approach is progressively gaining popularity in the software engineering community as it raises the level of abstraction in software development. In TALISMAN MDE framework, we combine the principles of the two most important initiatives, Model-Driven Architecture and Software Factories. Both have their pros and cons, and we select the best from each in TALISMAN MDE. To show the advantages of TALISMAN MDE, we have developed a systems generator and used it to create applications for controlling food traceability. The applications are being used in dairies with different manufacturing processes, using software developed specifically for each dairy by working only with models, without additional programming.
