What does it mean to collaborate while searching?
There are many different ways to characterize collaborative information seeking, many dimensions on which collaborative search systems can be categorized.
For the past few years Jeremy Pickens and I have been thinking that our model of collaborative exploratory search needs some further explication. Or maybe we’re just trying to understand it better ourselves. We have found that to explain what our model is, we have to simultaneously explain what our model is not. This has led to numerous discussions not only about the various dimensions of collaboration, but also about the relative importance among those dimensions for distinguishing between systems.
