Towards Syntax and Semantics of Hierarchical Contexts in Multimedia Processing Applications Using MARFL

We focus on defining context expressions in terms of initial syntax and semantics for an intensional MARF language, MARFL. It is there to allow scripting Modular Audio Recognition Framework (MARF)-based applications as context-aware, where the notion of context represents coarse-grained and fine-grained configuration details of a given MARF instance and a set of overloaded context operators borrowed from the Generic Intensional Programming Language (GIPL) @ and # to help with the task. This is a preliminary research on MARFL that has considerable practical implications on the usability of MARF's resources and beyond. In this paper we focus exclusively on the context specification for multimedia pattern recognition tasks and available MARF resources for its applications.
