If I have the geotagged articles, I can display it on OSM. However, my
computation logic is that during parsing the OSM data, the wikipedia entries
of the corresponding entities (e.g., node, way) should be crawled if they
exist. The problem is that many entities have the corresponding wikipedia
entries, but the wikipedia tags haven't been added in the OSM data. Hence
only relying on wikipedia tags may overlook much potential knowledge.
Yes, I agree the coordinates cannot be directly imported into OSM,
otherwise, some inconsistence issues may occur.

In addition to manual editing by contributors, I'm also thinking about
creating wikipedia tags or retrieving wikipedia entries automatically by
analyzing the information from the current OSM data.
