The navigation data comprises a plurality of point of interest (POI) models. Each POI model is a representation of a POI. At least a portion of the plurality of POI models are analyzed based on a data extraction model to determine a link between two or more POIs based on POI models corresponding to the two or more POIs. The two or more POIs are located within a predefined distance of one another. An entity of interest (EOI) model is generated based on the POI models corresponding to the two or more POIs, the determined link, and the data extraction model. The EOI model is stored for use in performing one or more navigation functions. ## Claims ### Claim 1 A method comprising: receiving, via a network apparatus comprising at least one processor, at least one memory, and at least one communication interface configured to communicate via at least one network, navigation data, the navigation data comprising a plurality of point of interest (POI) models, each POI model being a representation of a POI;
