The resultant model contained seven dimensions: i. ‘Spontaneous involved versus edited informational discourse’, ii. ‘Abstract informational versus narrative discourse’, iii. ‘Human-world orie...
The coverage of academic lexis is compared in a TED talk corpus (2,483 talks, 5,068,781 words) and a corpus of Yale University lectures (708 lectures, 5,523,791 words).
