This study introduces the Twitter Sentiment Geographical Index (TSGI), a global database of geotagged tweets. TSGI offers location-specific sentiment data to help measure Subjective Well-Being (SWB) and inform policy.
Area of Science:
- Computational social science
- Geospatial analysis
- Natural language processing
Background:
- Subjective Well-Being (SWB) is a key target for global development.
- Governments increasingly use SWB indicators alongside traditional metrics.
- A need exists for large-scale, location-specific sentiment data.
Purpose of the Study:
- Introduce the Twitter Sentiment Geographical Index (TSGI) database.
- Provide a comprehensive, open-source resource for sentiment analysis.
- Facilitate research on the geographical distribution of public sentiment.
Main Methods:
- Utilized deep learning and natural language processing.
- Analyzed 4.3 billion geotagged tweets globally since 2019.
- Developed multilingual sentiment measurements at the admin-2 level.
Main Results:
- Created the TSGI, the most extensive Twitter sentiment database to date.
- Covered 164 countries with daily sentiment frequency.
- Established a web platform for accessing TSGI data.
Conclusions:
- TSGI offers a novel tool for understanding geographical sentiment.
- The database supports research into Subjective Well-Being (SWB) indicators.
- Open access to TSGI data promotes wider scientific inquiry.

Geometric Mean
In cases of multiplicative data, the geometric mean is used for statistical analysis. First, the product of all the elements is taken. Then, if there are n elements in the...
Central Tendency: Analysis
The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.
The median, another measure,...
