The paper shows a system for automatic recognition of Signed Italian sentences. The proposed system is based on a multi-level architecture that models and manages the knowledge involved in the recognition process in a simple and robust way, integrating a common sense engine in order to deal with sentences in their context. In this architecture, the higher abstraction level introduces a semantic control and an analysis of the correctness of a sentence given a sequence of previously recognized signs. Experimentations are presented using a set of signs from the Italian Sign Language (LIS) and a sentence template useful for domotic applications, and show a high recognition rate that encourages to investigate on larger set of sign and more general contexts.
