# GDELT: Global Database of Events & Tone

The Global Database of Events, Language, and Tone (GDELT) is a massive, multi-modal, continually updated repository of structured representations of news media content, capturing global events, actor relations, linguistic sentiment, and associated metadata at granular spatiotemporal scales. It is designed to support computational social science, event detection, forecasting, and knowledge extraction across disciplines by providing exhaustive, high-frequency coverage of the world’s news cycle in machine-actionable form. Its architecture integrates event coding, language metadata, affect and sentiment analysis, and entity resolution, exposing these data through both schema-driven relational interfaces and knowledge graph paradigms suitable for downstream machine learning, evaluation, and retrieval-augmented generation workflows.

## 1. Data Architecture and Core Schema

GDELT’s data model is partitioned into several interlinked tables reflecting different levels of semantic annotation:

- **Events Table (e.g., expert.csv):** Each row encodes a single event, indexed by GLOBALEVENTID. Key fields comprise EventDate, Actor1Code/Actor2Code, standardized country/organization codes, EventCode (following the CAMEO ontology), GoldsteinScale (quantifying perceived impact), NumArticles/NumMentions/NumSources (measures of media visibility), AvgTone (average sentiment), and geolocational data at various granularities [2503.07584].

- **Global Knowledge Graph (GKG):** At the document/article level, this contains fields such as GKGRECORDID, DATE, SourceCommonName, V2Themes (thematic labels), V2Locations, V2Persons, V2Organizations, V2Tone (fine-grained affect vector), and GCAM (thousands of soft counts from four sentiment lexica and topical dictionaries) [2009.14281].

- **Mentions Table:** Links events and articles, assigning each mention confidence, mention-level tone, and locational context. It provides foreign-key joins to both Events and GKG tables, enabling fusion of document-level and event-level semantics [250
