    Publicado em April 27th, 2014Publications

    Two papers from ASSERT Members have been accepted for the International Digital Government Research Conference (dg.o 2014) to be held in Aguascalientes City, Mexico, on June 2014. Kellyton Brito, author of both papers, will attend the conference and present both papers. The first paper is entitled “Brazilian Government Open Data: Implementation, Challenges, and Potential Opportunities” by Kellyton Brito, Marcos Costa, Vinicius Cardoso Garcia and Silvio Meira.

    A brief summary of the paper is following: “Technological advances and real-time worldwide communications hold great promise for transforming the efficiency and effectiveness of public services through the ease of publishing and access to government public information or through the offer of new kinds of services. In this paper, we describe two initiatives, Rio Inteligente (Smart Rio) and Cidadão Recifense (Recife Citizen), which are based on Brazilian open-data repositories from the cities of Rio de Janeiro and Recife and deliver services for citizens and tourists, mainly (i) a health-unit finder based on user location and (ii) an online vaccination card. Based on the development experience of these two similar applications that use completely independent open-data repositories, this paper discusses the current state of Brazilian open-data initiatives, their challenges and difficulties, and draws some considerations towards a framework to build applications based on government data.

    The second one is entitled “Using Parliament Brazilian Open Data to Improve Transparency and Public Participation in Brazil” by Kellyton Brito, Misael Santos Neto, Marcos Costa, Vinicius Garcia and Silvio Meira. The paper abstract is following: “Government concerns about transparency date from 1957, but current technological advances and real-time worldwide communications hold promise to transform accountability, transparency, citizen participation and collaboration, in addition to offering better public services, by increasing efficiency and effectiveness and decreasing corruption in government. With these goals in mind, this paper describes Meu Congresso Nacional (My National Congress), a first prize winner application developed during the First Brazilian Parliament Hackathon focused on parliamentarians transparency by obtaining and analyzing data from several sources and displaying them on a user-friendly website. In addition, based on this development experience, this paper discusses the difficulties and challenges of developing applications based on Brazilian government data.

    This activity is part of the project “Social Machines and Research Team - SMaRT” and is one of the results of the research being done by ASSERT Lab.

    These papers will be soon available on ACM Digital Library. A new post will be done after the conference, presenting our impressions of the event and the feedback from research community about the work.

    The paper “Smart Cities Software Architectures: A Surveyauthored by Welington Manoel da Silva, Gustavo Henrique Rodrigues Pinto Tomas, Kelvin Lopes Dias, Ricardo Alexandre Afonso, Alexandre Alvaro and Vinicius Cardoso Garcia has been accepted for publication in the Software Architecture: Theory, Technology, and Applications (SA-TTA) Technical Track at the 28th Symposium On Applied Computing (SAC’2013).

    The conference will be held in March 18 - 22, 2013 at Institute of Engineering of the Polytechnic Institute of Coimbra (ISEC-IPC), Coimbra, Portugal.

    This activity is part of the project “Social Machines and Research Team - SMaRT” and is one of the results of the MSc research being done by Welington Manoel da Silva and Gustavo Henrique Rodrigues Pinto Tomas and PhD research being done by Ricardo Alexandre Afonso.

    A brief overview of the paper is given next

    The smart cities concept arises from the need to manage, automate, optimize and explore all aspects of a city that could be improved. For this purpose it is necessary to build a robust architecture that satisfies a minimal number of requirements such as distributed sensing, integrated management and flexibility.

    Several architectures have been proposed with different goals, but none of them met satisfactorily the needs that permeate smart cities.

    In this work various architectures are discussed, highlighting the main requirements that they aim to fulfill. Furthermore, based on different architectures with the most varied purposes, a set of requirements for the implementation of a smart city is presented and discussed.

    Publicado em September 12th, 2012Publications

    INES researchers had two papers accepted for publication in the 7th International Conference on Software Engineering Advances (ICSEA) 2012:

    1) “Evaluating performance of distributed systems with MapReduce and application traffic analysis” authored by Thiago Vieira, Paulo Fernando Soares, Marco Machado, Rodrigo Assad and Vinicius Garcia; and,

    2) “A Systematic Mapping Study on Domain-Specific Languages” authored by Leandro Nascimento, Daniel Viana, Paulo Silveira Neto, Dhiego Martins, Vinicius Garcia and Silvio Meira.

    Both papers are part of the research activities being performed in the project “Social Machines and Research Team - SMaRT”. We are gathering other members in this research group and creating a new one with a more general proposal, called Advanced Software Systems Engineering and Research Technologies (ASSERT): www.assertlab.com

    The conference will be held in November 18-23, 2012 - Lisbon, Portugal.

    A brief overview of both papers is given next:

    1) Abstract. Test, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the capacity of analyze large amount of data is a challenge. This paper proposes and evaluates the use of MapReduce programming model to deep packet inspection the application traffic of distributed systems, evaluating the effectiveness and the processing capacity of the MapReduce programming model for deep packet inspection of a JXTA distributed storage application, in order to measure performance indicators.

    2) Abstract. Domain-Specific Languages (DSLs) offer substantial gains in expressiveness and ease of use compared with general purpose languages. This way, DSLs have gained significant attention in industry and academy, as can be seen by the increased number of related publications in key conferences and journals. This paper aims to provide a broad view of the DSL research field by performing a Systematic Mapping Study. Adopting a detailed search strategy, 4450 studies were initially identified, and, after filtering, 1440 primary studies were selected and categorized using a particular classification scheme. So, this work presents the most popular application domains where DSLs have been applied, identifies different tools for handling DSLs, including language workbenches, and enumerates several techniques, methods and/or processes for dealing with DSLs.

    The paper “SMADL - The Social Machines Architecture Description Language” authored by Leandro Nascimento, Vinicius Garcia and Silvio Meira has been accepted for publication in the Doctoral Symposium of the 5th International Conference on Software Language Engineering (SLE) 2012 in Dresden, Germany.

    The conference will be held in September 25-28, 2012 and will be co-located with other well conferences in the area: 11th Generative Programming and Component Engineering Conference (GPCE’12) and the 4th International Workshop on Feature-Oriented Software Development (FOSD’12).

    This activity is part of the project “Social Machines and Research Team - SMaRT” and is one of the results of the PhD research being done by Leandro Nascimento.

    In order to give a brief overview of the paper, here is the abstract: We are experiencing a high growth in the number of web applications being developed. This is happening mainly because the web is going into a new phase, called programmable web, where several web-based systems make their APIs publicly available. In order to deal with the complexity of this emerging web, we define a notion of social machine and envisage a language that can describe networks of such. To start with, social machines are defined as tuples of input, output, processes, constraints, states, requests and responses; apart from defining the machines themselves, the language defines a set of connectors and conditionals that can be used to describe the interactions between any number of machines in a multitude of ways, as a means to represent real machines interacting in the real web. This work presents a preliminary version of the Social Machine Architecture Description Language (SMADL).
