The number of available legal documents has presented an enormous growth in recent years, and the digital processing of such materials is prompting the necessity of systems that support the automatic relevant information extraction. This work presents a system for ontology-based information extraction from natural language texts, able to identify a set of legal events. [...]
Non-communicable diseases burden is well-known and care for these diseases goes beyond patients’ engagement, extending to their family, friends, and acquaintances. The ability of social relations in alleviating the harmful effects of health risks is known as social support. Computing can be used to promote social support to enhance the care of non-communicable diseases. However, [...]
Este artigo apresenta o MASC, um modelo computacional para criação de cidades inteligentes assistivas. A aplicação da computação ubíqua na acessibilidade oportuniza soluções para pessoas com deficiências (PcDs). Diferente dos trabalhos relacionados, o MASC utiliza as interações das PcDs para composição de trilhas que são oferecidas como serviços. O modelo é genérico, auxiliando em diferentes [...]
There is a growing interest of using technologies to propose solutions for healthcare issues. One of such issues is the incidence of chronic diseases, which are responsible for a considerable proportion of worldwide mortality. It is possible to prevent the development of such diseases using tools and methods that instruct the population. To achieve this, [...]
The elasticity feature of cloud computing has been proved as pertinent for parallel applications, since users do not need to take care about the best choice for the number of processes/resources beforehand. To accomplish this, the most common approaches use threshold-based reactive elasticity or time-consuming proactive elasticity. However, both present at least one problem related [...]
As a result of rural and suburban migration to the cities, urban life has become a significant challenge for citizens and, particularly, for city administrators who must manage the sustainable use of resources such as energy, water, and transportation. Smart cities are the biggest vision to efficiently address these challenges through a real-time monitoring, providing [...]
he increased adoption of electronic commerce for selling products and services creates a new channel between consumers and vendors. Commonly, e-commerce platforms are assembled as proprietary and centralized solutions. This method has a high financial cost and slows the entry of both middle and small-sized companies into this communication channel. In this context, this article [...]
Internet of Things networks together with the data that flow between networked smart devices are growing at unprecedented rates. Often brokers, or intermediaries nodes, combined with the publish/subscribe communication model represent one of the most used strategies to enable Internet of Things applications. At scalability viewpoint, cloud computing and its main feature named resource elasticity [...]
A significant portion of the Brazilian population consists of people with hearing or visual impairment. Multimodal interaction systems do not suit the needs of a mixed audience, since they are designed for a specific user profile. We propose a model for a Multimodal Human Computer Interaction System (MMHCI) based on services, embedded on an assistive [...]
