We show that the IRPP is challenging from the computational point of view, present a mathematical programming formulation of the problem and discuss aspects of a solution method based on the column generation technique. We also show how some tools of probabilistic planning and agent-based modeling may be used to address important aspects of the problem.

The platform provides means for integration of different kind of data, collected automatically or with user intervention, to augment standard maps with accessibility information. The article shows the architecture of the platform, dedicating special attention to the smartphone applications we developed for data collection. The article also describes a preliminar experiment conducted on field, showing how the analysis of data produced by our solution can bring novel insights in accessibility challenges that can be found in cities.

This application connects to our Citizen Sensing platform, providing to city administrators an integrated view about issues in the city, such as sidewalks that are obstructed or in bad condition. If a representative amount of data is collected through people engagement, a significant number of issues will be registered, and analytics tools can be used to identify the impact these issues have on people with disabilities' lives. Consequently, we can use such information to build accessibility maps, and possibly to define an appropriate action plan to address the issues, optimizing resource allocation.

The communication is based on text messages, which makes the system easy to use and more accessible to communities where network connections are not well-developed and where the people do not have much experience with more advanced technological tools. The solution also provides a manage interface, through which administrators are able to mediate the messages and the users. We also implemented a matching procedure for the identification of related posts (e.g., it can check if there are compatible car ride offers and car ride requests) in order to make users aware of what is being posted and, even more important, adopt the technology.

Initiatives based on this concept are becoming crucial for designers of intelligent urban infrastructures, since they enable the collection of several types of relevant data that cannot be properly captured by traditional physical sensors. A large number of articles and projects associated with the topic appeared over the last few years, and with them the need for properly classifying and organizing these works. In this paper, we propose a taxonomy of citizen sensing initiatives and illustrate each of its dimensions through a survey of recent articles in the area. The proposed scheme also supports the identification and stimulates the development of projects addressing data collection methodologies that have not been properly explored so far. In addition, we present a platform capable of aggregating, analyzing, and extracting knowledge from data generated by physical and human sensing techniques. Finally, we report a real-world experiment in which we used our platform to map accessibility conditions of streets and sidewalks located in a four square kilometer area in São Paulo, Brazil. Our results show that a full coverage was obtained with the support of eight volunteers after only three hours, hence illustrating the effectiveness of the technology.

Even with the efforts of communities on reviewing user-contributed subtitles and with mechanisms in movie players to automate the discovery of subtitles for a given media, users still face lip synchronization issues. In this work we conduct a study on several subtitle files associated with popular movies and TV series and analyze their differences. Based on that, we propose a two-phase subtitle synchronization method that annotates subtitles with audio fingerprints, which serve as synchronization anchors to the media player. Preliminary results obtained with our prototype suggest that our technique is effective and has minimal impact on the extension of subtitle formats and on media playback performance.

Nevertheless, only a small fraction of Brazilians with disabilities actually work, due to lack of job qualifications. In this paper, we report on the early progress of an ongoing research agenda that investigates new educational and social engagement technologies to facilitate the qualification and inclusion of PwD in the Brazilian labor market. Based on our experiences working with multiple disability populations in a series of exploratory studies, we discuss relevant aspects to be considered in the design and implementation of a vocational training platform targeted at PwD.
