BuscaSigno: a construção de uma interface computacional para o acesso ao léxico da Língua de Sinais Brasileira

The paper describes SignRetrieval, a computerized system with a graphic-interface that allows deaf and hearing users to retrieve thousands of Brazilian sign language signs without depending on the knowledge of the Portuguese gloss that corresponds to the sign. It describes how the system was built and how it can be used to effectively retrieve Libras signs. It also describes the sign retrieving behavior of a user, thus shedding light upon strategies to use the system as a resource for the continuous expansion of the sign lexicon.
