Sangoan: Technology, Regions & Art
The Sangoan is a prehistoric lithic industry of sub-Saharan Africa, broadly dated to the later part of the Early Stone Age (ESA) and the transition to the Middle Stone Age (MSA), approximately between 500,000 and 300,000 years ago. First identified in the 1920s at Sango Bay in Uganda, the industry is characterized by heavy-duty core tools such as picks…

Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 137 structured relationships around Sangoan. Examples in this analysis include Sangoan → Characteristics → Associated with grubbing and woodworking and Sangoan → Dates → c. 500,000 – c. 300,000 years ago. The table shows each extracted connection, where it came from and its confidence.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Sangoan, one of the stronger structural bridges in this analysis connects Sangoan with Overview. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
