This paper presents the Concept-Action Grammar Generator (CAGG) system, which is an open source framework for natural speech-based interaction to be used in the semantic analysis of sentences. The goal of our framework is two-fold: i) to deliver a formalism associating a context-aware semantics to the words in a sentence; ii) to provide a common framework to benchmark different implementations of evaluators with the aim of improving speech-based interaction. To this aim, CAGG includes a specifically designed formalism for grammars definition as well as parsing mechanisms to automatically create and evaluate their structure. CAGG implements a deterministic evaluator which provisional performance related to a number of natural queries is discussed in terms of correct semantic associations and computational time.
