Overview:
The Brazilian National Institutes of Science are an initiative of the Brazilian Government to create centers of excellence in the state of the art research that can contribute to the scientific and technological development of Brazil and, above all, have a high contribution to the society. The Brazilian National Institute of Science and Technology for the Web is the result of the integration of researchers from four institutions: UFMG, UFRGS, UFAM, and CEFET-MG and it is coordinated by the Computer Science Department of the federal University of Minas Gerais (UFMG). The Web is the largest communication and information system built so far, and has a great impact on your daily lives. The INWeb was created to create and develop systems, technologies and applications that allow us to explore the use of the Web in a way that it can benefit the society. This can be done by studying and understanding the scientific and technological foundations of the Web, as well as its social repercussion.

Overview:
The aim of the Learning While Moving (LWM) project is to initiate a major collaboration between research groups of South America and France on ubiquitous technologies applied to the research area of mobile learning. In the LWM project, we intend to develop a context-aware mobile-learning environment (we call u-learning environment) to assist the creation of e-learning lectures, which can be adapted according to the current learning situation of the students, commonly named context. Context-awareness refers here to the capacity that a learning system has to detect students’ situation (location) and behaviors, to draw their attention on surroundings physical things or objects related to the current lesson, and to guide them in the discovery of new notions and knowledge. For instance, the current location of students, their proximity with real studied objects around, their skills, and the current state in the lecture workflow can be used to dynamically improve the u-learning activities performed by these students. As a case study, we propose to create a context-aware lecture in Geology that will execute on smartphones and that will help mobile geology students to learn in an interactive way, when they are on the field.

Overview:
The aim of this project is to initiate a major collaboration with South America on medical informatics and particularly on informatics applied to an important public health issue that is the home care for ageing people. We propose in this project to define a secure sensor-based environment for home-stay ageing people to help in today’s life (by alert systems), to transfer hospital technology, medical know-how and information from hospital to home in order to allow ageing people to stay at home as long as they can in an ethical environment. We propose in this project to create a service-based environment for elderly follow-up home-care in order to maintain ageing people as long as possible at their own home. The project will be structured around some main aspects: - global architecture of the service-based environment, which has specific characteristics: heterogeneous data sources containing different types of data (sensors, permanent data), device-adapted, dynamic, and context-aware; - connection between stream sensors data and permanent data; - adaptive interfaces for health networks environment (medical follow-up at home); As a main issue of the project, we propose to detail the theoretical aspects of the service –based environment defined by all partners and to begin a fruitful collaboration around medical IS for home-care.

This project is composed by a set of activities focused on the validation of a Consultation and Recommendation Platform for Semantic Web sites with special emphasis on the area of Health. The aim is to encourage the collective participation and develop a solid cooperation between the research groups. The objective is to specify an environment designed as a Web portal with access adaptable to different users depending on their cultural level and regional particularities. The central theme of this project came about quite naturally by the evolution and convergence of the various research projects conducted by the groups involved. These lines of research are focused on Distributed and Web systems and DBMS for queries on XML files, Web services, Information Systems in Health and Recommender Systems. During the four years project the groups involved will start bi or tri-lateral cooperation in order to create specific projects for funding the research and, especially, deployment of the systems specified.

Overview:
Web users have access to a large volume of information, products, and services that several times do not fall into their interests. To help these users perform their tasks and make the right decisions, providing them with accurate information and relevant products and services is deemed appropriate. For this purpose, recommender systems come into plan and emerge as complementary tools to search engines. Indeed, these systems are usually autonomous and pro-active and take into account users’ profiles. However, recommender systems first, do not always put forward the best recommendation, and second, are not well studied by the Web research community. Web services as an illustration of the focus of this community could benefit from recommender systems. For instance, Web services could be put together based on comments made by users over time. Briefly, Web services are applications that encapsulate computer services (processes, activities) that can be used by another software, interacting to support business processes. However, like products, there are many different services that may or may not be relevant to the current user need. Therefore, the application of recommendation techniques to Web services is an important initiative, and a lot of efforts need to be put into developing specific models (taking in account specific attributes and characteristics of these elements) facing the challenges that Web services pose. In that sense, this project aims at studying and developing recommendation techniques and models with focus on meeting the features of Web services. This would definitely have a positive impact on businesses (B2B and B2C) that nowadays aim at capturing more market shares.

Project: AdContext - Adaptability with contextual mobility and ubiquity (FINISHED)

Overview:
This project aims to study the aspects related to content adaption in mobile applications, specifically on mobile learning systems (m-learning). This involves many areas, including cooperative work (CSCW), geo-processing and adaptable multimedia presentations. Taking in account the many different adaption levels of the content involved in mobile applications, many scientific and technique problems are involved, specially those related to the transmission of information, the determination of the spatial content, the filtering and selection of content, the sharing and presenting of information, etc., all related to mobile devices, which are normally limited in terms of memory, processing and interface.

Overview:
This project deals with one of the challenges defined by the Brazilian Computer Society (SBC): "the management of large amounts of distributed multimedia data", specifically with the management of textual documents such as web pages or electronic documents, generated by public and private institutions. An important problem in this process is related to the establishment of relations and associations among documents.
