  "textContent": "In relation to the field of vehicle navigation, we describe a method of determining a position of a subject, comprising the steps of obtaining and storing an object dataset comprising object data indicative of multiple objects in an environment, including an indication of object parameters associated with each object, the object parameters including the location of the object in the environment and a semantic type classification associated with the object, obtaining environment data indicative of a region of the environment from a sensor associated with the subject, determining the presence of multiple observed objects in the environment data using an Artificial Neural Network to detect and classify each observed object, including determining one or more equivalent observed object parameters associated with each observed object including its respective semantic type classification, and determining the position of the subject using a probabilistic model, based on a comparison of the observed object parameters of each of the multiple observed objects with the equivalent object parameters of the objects in the object dataset including a comparison of the respective semantic type classifications.",
