DevSource has an interview with Ramesh Jain, with whom I have co-founded SEraja:
We’re all slaves to the keyword, Jain says. “This is a very primitive and poor mechanism” for finding information, he believes, and our understanding of what people are looking for is still very poor.
Today’s Web, says Jain, is a document Web. Everything is presented as a page. Yet, audio and video are becoming easier to store and disseminate, what Jain describes as an “event.” Figuring out how we’ll search through “events” is only one small piece of the problem. For example, as mobile phones become the primary client, people will use the devices to look for information: how do you design search tools for that platform?
