Brand Health Index
According to SentiOne’s business development manager Hurnik (personal
communication, August 28, 2018), the brand health index (i.e. BHI) is
calculated as: BHI = positive mentions / (positive mentions + negative
mentions). BHI of Pak’nSave is found to be 0.48, which is considered
only average during the examined period. The BHI is a simple index
derived from sentiment metrics, which can provide a general idea to
indicate the health of a brand. Companies can employ BHI together with
sentiments analysis to get an overall perspective of brand image in
social media.
