“Content analysis has traditionally relied on two basic methods: conceptual analysis and relational analysis. In conceptual analysis, a concept is selected, coded, and counted for Its presence in a text or corpus (set of texts). In relational analysis, the process goes one step further: it identifies a number of concepts and then examines the relationships among them. Also called “concept mapping,” it Is especially common in cognitive studies involving the construction of mental models (Carley & Palmquist, 1992). In conceptual analysis, meaning is assumed to reside in individual concepts, whereas in relational analysis, meaning is understood to derive from the relationship among concepts.  The key step In both types of content analysis is the coding of concepts, for it Is here that the analyst exercises considerable subjectivity,” (14).
