Abstract
Table 10: Wikipedia tests. Accuracy comparison for different article types.
['[BOLD] Article Type', '[BOLD] # of Articles', '[BOLD] Median Error (km)']
Article Type The author-provided location tags for Wikipedia articles each have a type associated with them. We investigated whether some of these types are more difficult for the algorithm to geolocate than others. Nineteen different types of tags were observed in the test set, in addition to a NULL (or missing) type. Ten of these types, including the NULL type, occurred at least 50 times in the 5476 articles that were tested. for each of these types. The table shows that airports and railway stations appear to be the easiest to geolocate, as they have the lowest median error. These types of articles are likely to name both the location and the nearby cities they serve, so our algorithm can expect to find a small cluster of results with good scores resulting in easy disambiguation.
