Automatic Results Identification in Software Engineering Papers. Is it Possible

This paper provides an analysis of the main methods for sentence classification in scientific papers and evaluates the feasibility of this technique in unstructured papers in Software Engineering area, in order to automatically find the study results in this area. Tests conducted with the existing methods using unstructured Test Software papers showed results far below those reported by the authors with input sets composed by structured health papers. Therefore, there is a need for new approaches to identify results in unstructured papers.

A Data Exchange Tool Based on Ontology for Emergency Response Systems

Considering the potential of Emergency Response Systems (ERS) in combination with crowd-based information, this article presents a data integration solution within the scope of the RESCUER project: an ontology based data exchange solution to allow semantic interoperability between ERS of Command and Control Centers, referred to as Legacy Systems, and RESCUER. The solution is implemented by the Data Integration with Legacy Systems (DILS) component which can be used for the exchange of incident information by any ERS. As a result, we evaluated simulated emergency cases by sending RESCUER emergency reports to another ERS with the DILS.

Este artigo discute a colaboracao entre estudantes na internet e a troca de conhecimento por meio desse canal de comunicacao. Propoe uma metodologia que visa potencializar as relacoes entre os usuarios de uma rede educacional situada num contexto especifico. Tal metodo tem como fundamento as teorias do contexto e a analise de redes sociais (ARS), para promover um mapeamento das redes estudadas.Refletir sobre curriculo escolar formal e comunidades de aprendizagem como metafora das TIC dinamizam os caminhos empiricos, construcoes criticas e aprofundamento da difusao do conhecimento como parte do processo de humanizacao/ tecnologizacao do homem. Oriundos de processos e movimentos contemporâneos, a consolidacao de ambientes computacionais nas escolas potencializa a construcao do conhecimento e a socializacao de praticas pedagogicas inovadoras. Esta investigacao assume as situacoes especificas curriculares, procura descobrir o que existe de mais essencial e caracteristico, partindo do conhecimento de curriculo e suas bases teoricas tradicionais, para a construcao da discussao sobre um curriculo em rede associada a instrumentalizacao das comunidades de aprendizagem.O sistema Moodle constitui-se atualmente numa das mais importantes ferramentas de apoio a cursos na Web. Apesar disto, seu modelo apresenta algumas deficiencias para uma estruturacao hierarquica e compartilhamento de materiais digitais entre disciplinas e turmas do seu ambiente virtual. Este artigo apresenta um estudo sobre a arquitetura central do Moodle, propondo a definicao de um novo nucleo, visando o aprimoramento destas caracteristicas.Estudo descritivo, qualitativo, com estudantes da 3a serie de Graduacao em Enfermagem de uma Universidade Publica de Sao Paulo, SP. Os participantes construiram Mapas Conceituais, por meio do software Cmap Tools®. Os dados foram coletados em um Grupo Focal e todos os sujeitos indicaram que o uso do software facilita e garante a organizacao, visualizacao e correlacao dos dados, porem houve dificuldades iniciais relacionadas ao manejo das ferramentas. Conclui-se, que o software Cmap Tools® favoreceu a construcao dos MC por seus recursos de formatacao, porem estrategias de orientacao deveriam ser implantadas. Como resultado, desenvolveu-se um manual para o uso do software Cmap Tool® em video Podcasting.Ha poucas iniciativas com respeito aos ambientes de virtuais para a divulgacao de materiais curriculares sobre modelagem matematica. Esses ambientes oferecem acesso as praticas pedagogicas em modelagem. Este trabalho apresenta um sistema Web para hospedar atividades de modelagem e materiais multimidia para descrever o desenvolvimento do ambiente de modelagem em sala de aula e apoiar outros professores na implementacao em suas praticas pedagogicas.A composicao e sequenciamento de Objetos de Aprendizagem sao discutidas neste trabalho a partir da representacao da estrutura conceitual de um dominio em termos das suas relacoes de dependencia. A composicao de Objetos de Aprendizagem e modelada a partir da estrutura narrativa de um discurso considerando-se os aspetos formais dos planos do conteudo e de expressao. O aspecto formal do conteudo da composicao e dado pelas pelos conceitos e seus relacionamentos e forma da expressao corresponde aos tipos de signos definidos pelo LOM. A estrutura da composicao obtida independe do tipo de midia utilizado e o modelo adequa-se as propostas de composicao adaptativas tanto do ponto de vista do meio como das disponibilidades de conexao.

An Approach for Semantically-Enriched Recommendation of Refactorings Based on the Incidence of Code Smells.

Code smells are symptoms of bad decisions on the design and development of software. The occurrence of code smells in software can lead to costly consequences. Refactorings are considered adequate resources when it comes to reducing or removing the undesirable effects of smells in software. Ontologies and semantics can play a substantial role in reducing the interpretation burden of software engineers as they have to decide about adequate refactorings to mitigate the impact of smells. However, related work has given little attention to associating the recommendation of refactorings with the use of ontologies and semantics. Developers can benefit from the combination of code smells detection with a semantically-oriented approach for recommendation of refactorings. To make this possible, we expand the application of our previous ontology, ONTOlogy for Code smEll ANalysis (ONTOCEAN), to combine it with a new one, Ontology for SOftware REfactoring (OSORE). We also introduce a new tool, our REfactoring REcommender SYStem (RESYS) which is capable of binding our two ontologies. As a result, refactorings are automatically chosen and semantically linked to their respective code smells. We also conducted a preliminary evaluation of our approach in a real usage scenario with four open-source software projects.

An Ontology-based Approach to Analyzing the Occurrence of Code Smells in Software.

Code Smells indicate potential flaws in software design that can lead to costly consequences. To mitigate the bad effects of Code Smells, it is necessary to detect and fix defective code. Programmatic processing of Code Smells is not new. Previous works have focused on detection and representation to support the analysis of faulty software. However, such works are based on a syntactic operation, without taking advantage on semantic properties of the software. On the other hand, there are several ways to provide semantic support in software development as a whole. Ontologies, for example, have recently been usedl. The application of ontologies for inferring semantic mechanisms to aid software engineers in dealing with smells may be of great value. As little attention has been given to this, we propose an ontology-based approach to analyze the occurrence of Code Smells in software projects. First, we present a comprehensive ontology that is capable of representing Code Smells and their association with software projects. We also introduce a tool that can manipulate our ontology in order to provide processing of Code Smells as it mines software source-code. Finally, we conducted an initial evaluation of our approach in a real usage scenario with two large open-source software repositories.

Toward a Scoring Schema to Rank Candidate Instances of Ontological Classes: Extracting Brazilian Portuguese Texts from the Web

With the emergence of Information Extraction Systems driven by ontologies, boosted by the Semantic Web, there is a need for the development of scoring schemas that enable the automatic classification of information. These schemas, even so little explored in the Portuguese language, provide measures used in the stage of classification of relevant instances to ontological classes. In this way, this paper presents: (i) a brief discussion about existing scoring measures based on PMI (Pointwise Mutual Information); (ii) new scoring measures based on PMI and Standard Deviation Calculation; and (iii) an evaluation of all discussed measures in the context of Brazilian Portuguese texts from the web.
