The following conventions are adopted in this book when explaining the analysis:
1 System networks are drawn using the conventions defined in Systemic Functional Linguistics. References to the names of systems occur in small caps and features occur in [square] brackets.
2 Bonds identified in affiliation analysis are shown in ALL CAPS and square brackets and ideation-attitude couplings are also shown in square brackets.
3 Emoji are referred to using the Common Locale Data Repository (CLDR) Short Names, which are presented in ALL CAPS.
4 Realisation of features from system networks are shown using –>Footnote 1
5 ‘ … ’ is used to indicate text has been abridged.
6 Anonymised information is shown in braces.
1 The more traditional notation of a downward slanting arrow was not used in order to avoid confusion with the DOWN-RIGHT ARROW emoji.
