Security Framework for Tuberculosis Health Data Interoperability Through the Semantic Web

One of the critical challenges in health information systems is interoperability. The clinical, strategic, and operational decision depends on quality data and the ability to exchange data inter-systems and inter-health organizations. The Semantic Web plays a cornerstone role as a technology to enable functional and semantic interoperability without substantial changes in existing systems and to improve data sharing capabilities and, consequently, its quality and completeness. However, a common concern is data security. In this context, this research proposes a framework for securing health data, with a real case scenario focused on tuberculosis data exchange over the Semantic Web. The needs of security for the Semantic Web were satisfied, helping to build trust in the data and promoting its use in contexts that were not initially created to openly disseminate data without a significant technological apparatus.

The Role of Virtual Reality to Enhance Cultural Communication

This paper aimed to recognize the role of virtual reality to enhance cultural communication by allowing to the participators who divided into three groups to watch the same substance in three different displays—virtual reality, normal video, images and text—to measure the process of retrieving information or events with a specific cue. The results of the study indicate that the virtual world experience enhances people's awareness of the culture. This new medium, VR, allows for participants to be immersed in the culture in ways that are not possible through the use of other media. Also, it can have an effective impact in cultural communication by allowing the participators to be virtually present at civilized events.

Commerce Web-Portal Redesigning Based on Usability Evaluation

Redesigning of the whole portal or some of its webpages does not always lead to a positive result despite the designers' expectations. Nowadays the opinion on how to carry out the redesign of web portals varies. A web portal being in service and in a wide use, a sudden change in its design may result in a drop of the number of clients. The usability evaluation has become important to make a decision on what design of webpages to choose. The paper proposes a method to redesign of commercial web-portals which is based on usability evaluation of some webpages. The evaluation can be undertaken by surveying the staff of the business organization where such a web portal is being developed. The hierarchy made of the Choquet integrals aggregates the results of the questionnaire and allows for the interdependencies between individual metrics of usability. Then, a decision about the redesign of a certain webpage is made on the basis of the aggregated results. The described experiment has shown a great impact of this innovative approach.

A Survey on Privacy Preservation in Location-Based Mobile Business

In mobile business (m-business), a client sends its exact locations to service providers. This data may involve sensitive and private personal information. As a result, misuse of location information by the third party location servers creating privacy issues for clients. This paper provides an overview of the privacy protection techniques currently applied by location-based mobile business. The authors first identify different system architectures and different protection goals. Second, this article provides an overview of the basic principles and mechanisms that exist to protect these privacy goals. In a third step, the authors provide existing privacy protection measures.

Exploring the Limitations of Responsive Design Through a Case Study Approach

Having an online presence is essential for any company regardless of its size and type of business. Users are currently striving to interact with companies through the web, regardless of their access device. In this sense, responsive web design emerged as a very useful technique that allows the dynamic adaptation of the design regardless of the size and resolution of the access device. Despite the unequivocal advantages associated with this technique, there are also limitations which turn this approach not feasible or advisable for all projects. This study, through the realization of five case studies, seeks to identify the main limitations of responsive design and responsive design frameworks. Additionally, this study suggests further development models that may be more effective in the dynamic adaptation of the design and contents according to the features of the access device, such as the adoption of adaptive design, use of native apps, and hybrid models.

An Information Retrieval System Based on Multiple Portlets

Information retrieval systems built with a service-oriented architecture have numerous advantages, and portlets are a key technology to implement services which interact with each other in the presentation layer. This work presents an efficient approach for the communication between the components of an information retrieval system based on multiple portlets in a single user interface. It also presents the architecture and the main methods of the system implemented as a case of use for this approach. It is shown that the proposed solution yields the best inter-portlet communication mechanism in each situation, while possessing the ability to deliver aggregated search and superior user experience.

QoS-Based Collaborative Filtering for Web Service Mining

Stored information in the databases is heterogeneous, from various sources, and of large volumes. The web service selection becomes nontrivial, as the users are easily overloaded by vast amount candidates. Using the keyword-based search method, users are struggling to choose the best web services among those having similar features. In the traditional methods, the users set different constraints and QoS parameters of a web service from what's claimed by the provider. Moreover, different researches challenge this problem, introducing semantic discovery process to enable relevant and desired search results. These approaches don't give importance to users' opinions and the selection history. The classical development of the ontology is typically entirely based on high human participation. In this paper, the authors use ontology-based querying, user profile to know the history, new collaborative filtering to calculate user, and query similarity and QoS as the final step for web service selection. The approach combines the syntactic and semantic methods to increase the selection precision.

Ontology-Based Analysis of Website Structure for Benchmarking in Retail Business

With the growing trend of digital transformation, electronic business has become a crucial part of business operations for many companies. Some of the most critical steps in successful transformation pertain not only to data and information acquisition and digitalization but also to adequate publishing and organization of these information resources. Companies share information through their websites, so the structuring of the web content becomes critical during the digital transformation of business. In this paper, the authors present a conceptual model of the managerial tool that is based on semantic analysis of web sites in order to obtain information about the structure of web sites in a particular domain. The resulting ontological model contains information about best practices in web information organization and can be a valuable resource for management when deciding on the organization of their own web content. The system is based on grounded theory and uses current information retrieval methods, natural language processing, semantic networks, and ontologies.

A Predictive Maintenance Planning System Implemented on a Web Platform

Predictive maintenance predicts failures and determines the equipment's remaining useful life, which provides maintenance time to plan their interventions, preventing breakdowns or reducing their impact. This paper presents a software application, implemented in a web platform, to support the implementation of a predictive maintenance plan. The developed system currently monitors certain parameters of a plastic injection molding machine. Furthermore, this system has real-time alerts that notify the maintenance team when the measured temperatures are outside the defined limits. Some extras were added, such as the report page, which calculates, automatically, performance indicators, the access management page, and a page that permits the realization of autonomous maintenance interventions, the verification of its fulfilment, and the visualization of the performed interventions' results. After the system's implementation, it was tested in real operating conditions. Following the test time, it was concluded that the desired parameters were measured correctly, which supported the work's continuation.
