Overview of total tweets, “action” tweets, and topic modelling analyses.

Times	Total of tweets streamed	# of action tweets	# of Topics	Coherence Score
Time 1 (February 2020)	318,749	33,659	9	0.54
Time 2 (June 2020)	305,851	72,798	12	0.55
Time 3 (October 2020)	303,636	59,415	11	0.50

Number of total tweets streamed for each time-point along with the action tweets identified by the BiLSTM model for each of the three sets of tweets. Coherence scores were obtained from topic modelling analysis of the number of action tweets reported to be acceptable at levels ≥0.50.
