- Facebook has recently decided to allow search engines like Google to crawl their member pages to make them accessible to a much larger audience. For those that don't want their profile exposed to the world, Facebook provides an opt-out. This is a good move by Facebook that will likely draw in more members, and it will certainly be useful to social networking researchers.
- While on the subject of Facebook, have you seen the Friend Wheel? It creates a graph of your friends and connects your friends who are friends with each other. A really dense graph means your friends are very cliquish. A sparse graph would mean you have friends from a very broad range of people. Looks like I'm somewhere in the middle:
- The first Semantic Robot Vision Challenge was held in late July. The competition required robots to locate objects in a room by first utilizing the Internet to search for pictures of the objects. For example, if the robot had to find a pencil, it would first search Google Images for pencil and then, based on the results, attempt to locate something similar in the room. I've tried teaching Ethan what "sleep" is using a similar method, but he hasn't yet been able to locate it anywhere in his room.
- An interesting paper popped up in arXiv this week: Open Access does not increase citations for research articles from The Astrophysical Journal. The authors conclude:
There are a number of excellent arguments in favor of changing the scientific publication system to an open access model. The open access citation advantage is not one of them.Why doesn't making a paper OA increase its citations? The authors admit in the introduction:
...in a well funded field like astrophysics essentially everyone who is in a position to write research articles has full access to the literature.So, if everyone has paid access to everyone else's papers, there is no OA advantage. I don't think anyone would have thought otherwise. The problem is, most disciplines are not well-funded enough to provide everyone paid access to the literature, and hence the OA movement. So the conclusions reached by the authors seem trivial to me. Am I missing something?
- Is Apple the next Microsoft (monopolist)? Dan Frakes doesn't think so.
