Editor's Notes

  • Friends, Countrymen, Googlers, I come to bury relevance, not to praise it. Well, that’s overstating the case. But I am here today to challenge your approach to information access, and more importantly to tease out and question its philosophical underpinnings. I realize that I’m singling you out as Googlers for holding a belief that is far more widely held, but you are the standard bearers of relevance. And you invited me.  Notes: this presentation was delivered at the Google NYC office on 1/7/09. The title is an allusion to Tefko Saracevic’s article, “Relevance Reconsidered”. If you are interested in learning more about the history of relevance I highly recommend his 2007 Lazerow Memorial Lecture on “Relevance in information science” (http://mediabeast.ites.utk.edu/mediasite4/Viewer/?peid=fb8f84cb-9f82-499f-b12c-9a56ab5cf5ba).
