Co-occurrence
Two entities (or terms) appearing together within some window — sentence, paragraph, document — are co-occurring.
Last updated
Two entities (or terms, or concepts) co-occur when they appear together within some window — a sentence, a paragraph, a document. Counting and graphing co-occurrences surfaces relationships that are implicit in how the corpus talks about its subjects, without needing an explicit “relationship” annotation.
Why it matters for your research. Co-occurrence graphs are the classic DH visualisation — who appears in the same paragraph as whom, which places share political context, which concepts are argued together. They are interpretable because they come directly from the text, with no model fabrication in between.
In Archēglyph. On the 90-day roadmap, scoped per cluster with a configurable window. Depends on NER landing first.
Not to be confused with. Correlation over time — diachronic — is a different question: when entities appear together. Co-occurrence is a structural measure within a chosen window.
