The 18th International World Wide Web Conference (WWW 2009) was recently held in Madrid. This is the forum in which Larry and Sergey introduced the "Google" search engine back in 1998. Conferences like WWW are highly beneficial for all attendees, as they provide a forum for constructive interactions and discussions among the diverse, global community that is contributing so much to the advancement of the web. As one of the major sponsors this year, Google contributed significantly in various scientific and social forums. Here's a short report of those activities:
- Google and the Prado Museum collaboration: In January 2009, we announced a collaboration between Google Earth and Spain’s Museo del Prado, which lets people zoom in on some of the gallery’s main portraits and view them in a resolution so fine -- up to 14,000 megapixels -- that even individual brush strokes and cracks in the varnish are clearly visible. The Prado Museum has become the first art gallery in the world to provide access to and navigation of its collection in Google Earth. The initiative includes 14 of the Prado’s most famous paintings -- works by Francisco de Goya, Diego Velázquez, Hieronymus Bosch, Peter Paul Rubens, and more. Such ultra-high resolution imaging, enabling users to virtually feel, see and be present with the original masterpieces, is just one way in which the web can make important contributions to the art community. To celebrate this, Google hosted an event at the Prado Museum, where guests received a guided tour of some of the main exhibits, and had the opportunity to network with fellow researchers, academics and engineers, as well as Google's own Vint Cerf.
- Research Contributions: Google contributed to the WWW conference by authoring or co-authoring several papers and presentations. I gave a keynote speech on The Continuing Metamorphosis of the web (you can read more about that topic on the Google Research blog). Some other papers to highlight are:
-- Estimating the ImpressionRank of Web Pages, Z. Bar-Yossef & M. Gurevich
-- Detecting The Origin Of Text Segments Efficiently, O. Abdel-Hamid, B. Behzadi, S. Christoph & M. Henzinger
-- What's Up CAPTCHA? A CAPTCHA Based On Image Orientation, R. Gossweiler, M. Kamvar & S. Baluja
-- Computer and iPhones and Mobile Phones, oh my! A logs-based comparison of search users on different devices, M. Kamvar, M. Keller, R. Patel, and Y. Xu
-- Collaborative Filterin for Orkut Communities: Discover of User Latent Behaviour, W. Chen, J. Chu, J. Luan, H. Bai, Y. Wang, and E. Chang.
-- Fast Dynamic Reranking in Large Graphs, P. Sarkar, A. Moore
-- WEB 2.0: Blind to an Accessible New World, J. Hailpern, L.Guarino-Reid, R. Boardman, S. Annam
-- How Opinions are Received by Online Communities: A Case Study on Amazon.com Helpfulness Votes, C. Danescu, G. Kossinets, J. Kleinberg, L. Lee
-- Bid Optimization for Broad Match Ad Auctions, E. E. Dar, Y. Mansour, V. Mirrokni, M. Muthukrishnan & U. Nadav
-- General Auction Mechanism for Search Advertising, G. Aggarwal, S. Muthukrishnan, D. Pal & M. Pal
- Best Paper Award and the Internet Monetization Track: The WWW program committee changed the best paper and poster process this year. They first chose several nominated papers from different tracks, and after seeking feedback from conference attendees, they chose their best paper: Ashish Goel's and Kamesh Munagala's Hybrid Keyword Search Auctions. The authors of this paper propose a unified approach to an auction for cost-per-click and cost-per-impression settings, and show promising properties of their proposed auction. The paper was presented in the Internet Monetization Track at WWW — a new track which, despite its short term at WWW, became very popular this year. Other tracks like web search, data mining, and the social web have been active at WWW for years and already attract many high-quality research papers. The best poster award went to a paper co-authored by Google's Monika Henzinger about Purely URL-based Topic Classification.
