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.
