How we built the ESG/Coronavirus Semantic Map
In order to map the raw social media graph to ESG keywords, we analysed the hashtags we have found (the nodes) and we grouped hashtags together by topics, using topic classification and spell checking techniques to clean up the raw data. We then displayed a graph of coalesced tags, where all tags falling under the same topic are coalesced into one node, e.g. #coronavirus, #covid19, #coronaoutbreak, #fightcovid19 would all fall under the topic Coronavirus.
