Abstract in Portuguese
Modernas tecnicas de biologia molecular sao utilizadas para quantificar os niveis de expressao genica de amostras celulares, frequentemente submetidas a diferentes condicoes experimentais. A genomica funcional e a area da bioinformatica responsavel pela caracterizacao do papel funcional dos genes e processos biologicos associados. A analise de expressao genica requer o uso (integrado) de diversas ferramentas de analise para a obtencao de respostas as questoes biologicas de interesse. Uma plataforma de analise pode ser utilizada para facilitar a integracao sintatica e semantica destas ferramentas. Tal plataforma deve oferecer acessibilidade, reprodutibilidade e transparencia, de modo a promover a colaboracao e a disseminacao da pesquisa cientifica. A plataforma SemanticSCo foi concebida para prover suporte a composicao semantica de servicos de analise de expressao genica. Contudo, esta plataforma, em sua versao standalone, apresenta baixa acessibilidade, alem de nao prover suporte para a reproducao e o compartilhamento dos workflows desenvolvidos por seus usuarios. O principal objetivo deste projeto foi ampliar a acessibilidade da plataforma SemanticSCo, bem como introduzir suporte para a reproducao e compartilhamento de workflows. Como resultado principal, desenvolvemos uma nova versao da plataforma SemanticSCo, chamada SemanticSCo Web. A plataforma SemanticSCo Web possui uma interface simples e amigavel, contribuindo para o desenvolvimento colaborativo de pesquisa cientifica reproduzivel no dominio da genomica funcional. Adicionalmente, desenvolvemos uma API chamada SIBRI para permitir a execucao automatica, via framework Activiti, de servicos RESTful modelados como processos BPMN. O uso desta API facilita a integracao de aplicacoes desenvolvidas na linguagem Java e que fazem uso de servicos RESTful, dado que esta API prove suporte a interacao com o usuario em um ambiente web para que o mesmo possa prover valores de parametros que serao utilizados na execucao de um dado servico. Desta forma, a API SIBRI simplifica a incorporacao de novos servicos na plataforma SemanticSCo Web.

Abstract in English
Modern molecular biology techniques are used to quantify the levels of gene expression of cellular samples, often submitted to different experimental conditions. Functional genomics is the area of bioinformatics responsible for the characterization of the functional role of genes and associated biological processes. The analysis of gene expression requires the (integrated) use of several analysis tools to obtain answers to a given biological question. An analysis platform can be used to facilitate the syntactic and semantic integration of these tools. Such platform should offer accessibility, reproducibility and transparency in order to promote collaboration and dissemination of scientific research. The SemanticSCo platform was designed to provide support for the semantic composition of gene expression analysis services. However, this platform, in its standalone version, presents low accessibility, and does not provide support for the reproduction and sharing of developed workflows. The main objective of this project was to increase the accessibility of the SemanticSCo platform, as well as to introduce support for the reproduction and sharing of workflows (transparency). As a main result, we have developed a new version of the SemanticSCo platform, called SemanticSCo Web. The SemanticSCo Web platform has a simple and user-friendly interface, contributing to the collaborative development of reproducible scientific research in the functional genomics domain. Additionally, we have developed an API called SIBRI to allow the automatic execution, via Activity framework, of RESTful services modeled as BPMN processes. The use of this API facilitates the integration of applications developed in Java that uses RESTful services, since this API provides support for the interaction with the end user in a web environment so s/he can provide parameters to be used in the execution of a given service. In this way, the API SIBRI simplifies the incorporation of new services in the SemanticSCo Web platform.
