Viral is a phenomenon that rises due to both expansion of the personal computer s access and the settlement of the cyberspace, which behavioral paradigm is the all-to-all communication. In order to study the viral phenomenon, it is used different social-cognitive approaches which include mainly the Relevance Theory (Sperber & Wilson, 1995) and Memetics (Dawkins, 2001). First, we seek to understand the viral structure, as well as its means of propagation and social transmission. Then, we analyze the impact that the viral has in the accessibility. Finally, we verify the chief pragmatic functions that the viral can exert in virtual dialogues. / Este trabalho tem como objetivo entender o aspecto viral das m?dias sociais com rela??o ? dimens?o comunicativa da l?ngua. Os virais s?o um fen?meno que nasce gra?as ? amplia??o de acesso dos computadores dom?sticos e ao povoamento do ciberespa?o, cujo paradigma comportamental ? a comunica??o todos-todos. Para melhor estudar o fen?meno viral, faz-se uso de diferentes propostas de natureza cognitivo-social, as quais incluem, majoritariamente, a Teoria da Relev?ncia (Sperber & Wilson, 1995) e a Mem?tica (Dawkins, 2001). Primeiramente, buscamos entender a estrutura dos virais, assim como os meios de propaga??o por onde ocorre a transmiss?o social. Em seguida, analisamos o impacto que os virais t?m na acessibilidade. Por fim, verificamos as principais fun??es pragm?ticas que os virais podem exercer em di?logos virtuais.

The communication aspects are the focus, with their phases, between the main actors of the software development project in the requirement analysis step: analysts and users. A model of requirement analyses which considerer the communication and Information Science knowledge issues in the formalization of the system specifications are presented. This model helps to identify the important aspects, in the information user domain, for externalized and formalized to reach a requirement definition as near as possible of reality. / Esta pesquisa busca compreender, na etapa de defini??o do sistema, os problemas de valoriza??o, prospec??o e formaliza??o da informa??o, focando os aspectos da comunica??o, e suas diversas etapas, entre os atores principais de um projeto de desenvolvimento de software na fase de an?lise de requisitos: analista e usu?rio. Um modelo de an?lise de requisitos que considera as quest?es comunicacionais e do conhecimento da Ci?ncia da Informa??o, na formaliza??o das especifica??es do sistema ? apresentado. Este modelo ajuda a identificar os aspectos mais importantes, que est?o na esfera do dom?nio de informa??o do usu?rio, de modo a serem externalizados e formalizados para que se consiga chegar a uma defini??o de requisitos mais pr?xima da realidade.
