Cognitive Psychology proposes three types of information storage for the general pattern of memory: Sensory Memory (SM), Short Term Memory (STM), and Long Term Memory (LTM). In the LTM, information is stored on a permanent basis, its capacity is extremely large and it keeps information indefinitely. One of the sub-systems of LTM is the declarative or conceptual memory which is composed in turn by a semantic memory as well as by an episodic one. The organization of knowledge in the semantic human memory has a reticular structure, which means that knowledge is represented by semantic nets, through propositional representations.These are semantic units which articulate a concept (node 1) with another concept (node 2) joined by means of a significant relation. The way in which information is learned (acquisition phase) is important, for the organization of knowledge in the memory as much as for the retrieval phase. The best way to learn is to integrate the new information in the format in which memory operates to retrieve/recall, that is to say in the format of semantic nets and conceptual maps. In the present article a specimen of cognitive software is presented: Knowledge Master, which follows the outline of representation of knowledge in the semantic memory by means of the generation of conceptual maps and semantic nets. Its application is exemplified by visualization of semantic nets regarding concepts developed in this same article.
