A Grading System for Evaluating Geospatial Entity Connectivity from Texts Using Co-occurrences, Semantic Similarity and Geodesic Distance

Eirini Katsadaki, Georgios Bougas & Margarita Kokla · Journal of Geography, Environment and Earth Science International · 2026

Extracting entity connectivity from texts is important for uncovering how places relate within real-world discourse. While structured data is informative, textual data captures rich contextual and semantic knowledge, enabling us to identify hidden networks of interdependence and...
