Two months ago I made a post about the fun little news application on the Nintendo Wii. Dan Burd responded to the post with this comment criticizing some of Wii News’ interface assumptions: “I think it’s limiting to say that each news story only pertains to one location. Many news stories are overviews of the relations between two or more countries. I’m guessing the AP thing would place them at whatever city the reporter is reporting from. I think that’s a bit misleading.” If you ask me, he is spot on.
Burd’s comment refers to global news, but the meaning also applies to other scopes. To use his terminology, it is limiting and potentially misleading for any news interface to require that each story pertain to exactly one location.
To prove the point, here are some abstracted stories that wouldn’t fit well into such a restrictive schema:
- Events that take place in one area but are directly relevant to another.
- Interactions between multiple communities.
- Any situation where affected location and occurring location are different. (This includes stories with global relevance).
- Related events that happened in more than one place.
The list could go on, but you probably get the picture.
In database speak you would call the desired relationship between news articles and locations as “many to many,” meaning one article can have many locations, and one location can have many articles. From a programming standpoint, it is simple enough to address that relationship when designing your software; it’s just a matter of recognizing that it’s there.
Since the technical implications of having multiple location tags aren’t too severe, I bet a lot of people already do it (it isn’t an advertised feature on most geocoded news sites as far as I can tell, so I don’t know for certain). For anyone that doesn’t, though, I’m bringing it up to put it on the radar as a really important feature for any news site that uses location information to categorize and display its articles.
A quick warning: adopting this slightly added complexity means you have to be sure not to confuse the reader. (If you are using the map as a way to help users filter news instead of browse, then you are probably pretty safe.)
