AI Analysis
This method addresses the need for automated sentiment index generation in economics, though it appears incremental as it builds on existing index generation techniques.
The authors tackled the problem of automatically generating public sentiment indices by proposing the Wasserstein Index Generation model (WIG), and demonstrated its effectiveness by applying it to create an Economic Policy Uncertainty index.
I propose a novel method, the Wasserstein Index Generation model (WIG), to generate a public sentiment index automatically. To test the model`s effectiveness, an application to generate Economic Policy Uncertainty (EPU) index is showcased.
