The emergence of new, textual ways of publicly accessible discussions among citizens has sparked increased interest among researchers who aspire to measure, via content analysis, different normative criteria of public deliberation in order to evaluate (online) discussion. There seems to be an emerging consensus among researchers on what will be called here "(online) deliberation analysis" - a specific content analysis employed as a tool for evaluation of public deliberation. (Online) Deliberation Analysis is characterised by a specific selection of unit(s) of analysis, selection of cases, and most of all analysis of specific variables: normative ideals of public deliberation. The aim of this article is threefold: first, to present the normative requirements of deliberation as presented in theoretical thought on the public; second, to provide a review of empirical research aimed to analyse these requirements and finally, to propose some possible improvements for future research.
