Além disso, a maior parte dos problemas que ocorrem durante o processo de desenvolvimento de software geralmente é causada por falhas nas fases iniciais. Diante disso, tecnologias que busquem compreender e descrever os processos de negócio e que permitam uma visão mais próxima do domínio, com alto grau de abstração, como o Desenvolvimento Orientado por Modelos (<i>Model-Driven Developement</i> -- MDD) e a Modelagem de Processos de Negócio (<i>Business Process Modeling</i> -- BPM) podem contribuir para uma melhoria da qualidade da elicitação e especificação de requisitos de software, sobretudo quando apoiadas por ferramentas que ofereçam meios para automatização do processo. Este artigo apresenta uma proposta de abordagem baseada em MDD e BPM voltada para o processo de Elicitação de Requisitos.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121833795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Automatic Speech Recognition (ASR) systems still face several issues that limit their performance, specially due the variability and complexity of the speech communication. One of these issues concerns the presence and influence of context information. We argue that if, well handled, context information can significantly improve the speech understanding accuracy. This paper provides a formalization of context and proposes an approach to its use on the adaptation of language model in ASR systems. This proposal is applied to the development of a remote control to mobile robotic devices. Results show a decrease up to 2.67% and 3.3% on WER and WIL rates, respectively.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127958193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In large size discrete event systems occur very complex situations that can be approached from a formal methodological perspective. Petri Nets are a very powerful paradigm that can be used to model, analyze and synthesize concurrent systems based on discrete events. Our work focuses on the context of systems engineering and the use of formal methods to deal with processes that occur in distributed contexts that, when not properly coordinated, could produce unwanted results. In the case of transport systems, theses consequences can be catastrophic.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123016948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the design perspective, it is based on decoupling the solving intelligence from the domain expertise, allowing to reuse the same solver for multiple, usually related problem domains. There are few works in which hyperheuristics have been designed and evaluated in distributed environments. In this paper, we propose a conceptual design of a distributed hyperheuristic architecture, from the problem domain deploying perspective, which allows to communicate different optimization environments (such as solver and domain) and to offering a \"solving service\". Different problems domains could be addressed using an encapsulated hyperheuristic solver, and through well defined interfaces, users can provide different heuristic components to perform the optimization process. The proposed architecture is only an initial step for which different modeling, design and implementation issues must be addressed. Such research should be focused on defining how conceptual design contributions must be leveraged to implement well defined interfaces, capable of connecting hyperheuristic solvers and problem domains within distributed environments.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126503166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
