In A Visual Way to See What is Changing Within Wikipedia, Jennifer Shockley writes:
Wikipedia is a go to source for quick answers outside the classroom, but many don’t realize Wiki is an ever evolving information source. Geekosystem’s article “Wikistats Show You What Parts Of Wikipedia Are Changing” provides a visual way to see what is changing within Wikipedia.
Is there any doubt that all of our information sources are constantly evolving?
Whether by edits to the sources or in our reading of those sources?
I wonder, have there been recall/precision studies done chronologically?
That is to say, studies of user evaluation of precision/recall on a given data set that repeat the evaluation with users at five (5) year intervals?
To learn if user evaluations of precision/recall change over time for the same queries on the same body of material?
My suspicion, without attributing a cause, is yes.
Suggestions or pointers welcome!
