In this paper, we describe an on-going project called Concept and Sensor Networks (CSN). The development of this project has been described in past PSMP workshops [1]. The purpose of the project is to develop a framework for entities that can process sensor information into concepts. One of the features of this proposed network is the ability of the entities to use language communication to exchange concepts. These entities can potentially represent concepts, knowledge and information using different kinds of semantics. To further this project, we will implement the proposed framework using physical and virtual sensors. In this paper, we overview the key components of the project, primarily focusing on lexical acquisition and the corresponding algorithm.
