The field of text mining is divided mainly in terms of different methodologies, while the field of text analysis can be divided into several different approaches that are each based on a different way of theorizing language use. Before discussing some of the special challenges associated with using online data for social science research, next we review six of the most prominent approaches to text analysis. As we will see, many researchers who work with these approaches are finding ways to make use of the new text mining methodologies and tools that are covered in Parts II, III, and V. These approaches include conversation analysis, xe "analysis of discourse positions"analysis of discourse positions, critical discourse analysis (CDA), content analysis, Foucauldian analysis, and analysis of texts as social information. These approaches use different logical strategies and are based on different theoretical foundations and philosophical assumptions (discussed in Chapter 4). They also operate at different levels of analysis (micro, meso, and macro) and employ different selection and sampling strategies (see Chapter 5).
