The ultimate set of indicators was then created primarily based on divergence between the 2 indexes.

The authors mentioned their work underscored the importance and coverage implications of data contained on social networks however acknowledged additional research was wanted to interpret the info.

In addition they famous that there have been a number of instances of a Twitter-based indicator been thrown off beam by a viral social media occasion, for instance when the sale of an condominium for a record-breaking $236 million (roughly Rs. 1,700 crores) in 2014 led to a flurry of tweets containing variants of the phrase “dearer”.
