1. An apparatus for matching a first point of interest (POI) dataset including one or more first POI entities with a second POI dataset including a plurality of second POI entities in a 2D region, each respective first POI entity of the first POI entities comprising first coordinate data and one or more first label tokens indicative of a label of the respective first POI entity, each respective second POI entity of the second POI entities comprising second coordinate data and one or more second label tokens indicative of a label of the second POI entity, the apparatus comprising:
processing circuitry configured to:
determine, for each respective first POI entity of the one or more first POI entities based on the first coordinate data of the one or more first POI entities, a subset of the plurality of second POI entities;
determine, for each respective first POI entity of the one or more first POI entities, a composite matching score with each of one or more respective second POI entities of the subset of the plurality of second POI entities, wherein the composite matching score is based on a coordinate matching score and a label matching score, wherein the coordinate matching score depends on a geographical distance between the respective first POI entity and the respective second POI entity, and wherein the label matching score depends on a local context relevance of the one or more first label tokens of the respective first POI entity; and
match, based on the composite matching score, each respective first POI entity of the one or more first POI entities with the second POI entities of the subset of the plurality of second POI entities.
