compute_doi {globaltrends}

Aggregate keyword-country data and compute DOI

Description

The function computes degree of internationalization (DOI) for object keywords. Degree of internationalization is measured based on the distribution of country search scores.

Usage

compute_doi(object, control = 1, locations = "countries")

## S3 method for class 'numeric'
compute_doi(object, control = 1, locations = "countries")

## S3 method for class 'list'
compute_doi(object, control = 1, locations = "countries")

Arguments

object

Object batch for which the keyword-country data is aggregated and DOI is computed. Object of type numeric.

control

Control batch for which the search score is used. Object of type numeric.

locations

List of locations for which the search score is used. Object of type character. Defaults to "countries".

Details

The function uses an inverted Gini-coefficient as measure for the degree of internationalization. The more uniform the distribution of search scores across all countries, the higher the inverted Gini-coefficient and the greater the degree of internationalization. In addition to the Gini-coefficient, the package uses inverted Herfindahl index and inverted Entropy as measures for internationalization.

Value

Message that data was aggregated successfully. Data is written to table data_doi.
