In this communication we present some fragments of a new, multidisciplinary theory of knowledge as certified shared beliefs of epistemic communities and a typology of knowledge and epistemic communities, including scientific communities and the public as a whole, as a basis for a multidisciplinary study of popularization discourse. Besides transformations between different types of knowledge, popularization also involves recontextualization of knowledge from scientific to everyday knowledge. In a study conducted with Helena Calsamiglia, we analyzed press reports in Spanish newspaper El País about the presentation of the completion of the sequencing of the human genome and found that popularization not only features the usual discursive means of new knowledge introduction (such as definitions and metaphors), but also a limited set of fixed categories such as Location, Composition, Type, Size and Number, which link old with new knowledge. It is assumed that these categories are expressions of underlying schemas of knowledge representation.

In this communication we present some fragments of a new, multidisciplinary theory of knowledge as certified shared beliefs of epistemic communities and a typology of knowledge and epistemic communities, including scientific communities and the public as a whole, as a basis for a multidisciplinary study of popularization discourse. Besides transformations between different types of knowledge, popularization also involves recontextualization of knowledge from scientific to everyday knowledge. In a study conducted with Helena Calsamiglia, we analyzed press reports in Spanish newspaper El País about the presentation of the completion of the sequencing of the human genome and found that popularization not only features the usual discursive means of new knowledge introduction (such as definitions and metaphors), but also a limited set of fixed categories such as Location, Composition, Type, Size and Number, which link old with new knowledge. It is assumed that these categories are expressions of underlying schemas of knowledge representation.
