location: any part of space

Scope

References to points in space, one-, two- or three-dimensional regions of space, and references to space as a whole are also are annotated as location. location annotation covers both exact and imprecise as well as both absolute and relative references to space.

Syntactic constraints

Names and nominal mentions (see Span annotation: Name mention annotation and Nominal mention annotation). Additionally, prepositions relating to the boundaries of spatial regions such as above are included in the extent of location annotations.

Examples

The semantic scope of location annotations matches that of spatial regionBFO (see Ontological basis: Top-level organization). In terms of “classical” named entity recognition tasks, the semantic scope of location encompasses the scope of LOC(ation) and overlaps significantly with GPE (Geo-Political Entity) [5].
