I read some where that there was a problem with using Facebook friends as actual friends. Many people have well over 200 “friends” on Facebook, and in some cases they may not have even have met the person. Definitely a problem when determining social relevance.
I was looking through the JSON API results from the photos feed and I realized something. Now please excuse me if this is a pretty common technique (I haven’t read this before), but I realized you can use the photo tagged results to match “real” friends. If you and a friend are tagged in the same photo, it’s a pretty good guess you two actually know each other. You could probably even find likely “best” friends by using the frequency of tagged photos in the result sets.
I’m guessing Facebook has already taken advantage of this obvious technique, but it’s neat to know these new APIs make that possible for us.
Sample of JSON tags ouput:
"tags": {
"data": [
{
"id": "820125496",
"name": "Kurt Jarchow",
"x": 24.4444,
"y": 31.9328,
"created_time": "2010-02-14T16:09:27+0000"
},
{
"id": "539581074",
"name": "Craig Jarchow",
"x": 61.1111,
"y": 32.7731,
"created_time": "2010-02-14T16:09:27+0000"
}
]
},
