"Towards a Distributed Search Engine"

The Distributed Systems Group of the Information Systems Institute invites to the following talk: "Towards a Distributed Search Engine". Lecturer: Ricardo Baeza-Yates - VP of Yahoo! Research for Europe and Latin America, leading the labs at Barcelona, Spain and Santiago, Chile - http://www.dcc.uchile.cl/~rbaeza - Date: Tuesday, 30 November 2010 - Time: 11:00 h - Place: EI 10, Gußhausstraße 27-29, ground floor Abstract: - In the ocean of Web data, Web search engines are the primary way to access content. As the data is on the order of petabytes, current search engines are very large centralized systems based on replicated clusters. Web data, however, is always evolving. The number of Web sites continues to grow rapidly (Over 200 millions nowadays) and there are currently more than 20 billion indexed pages. On the other hand, Internet users are above one billion and hundreds of million of queries are issued each day. In the near future, centralized systems are likely to become less effective against such a data-query load, thus suggesting the need of fully distributed search engines.
