Bessensap 2012 en het diepe web

Tuesday, June 5th, 2012, posted by Djoerd Hiemstra

Djoerd bij Bessensap in het Museon Meer dan 99 procent van het wereldwijde web is op dit moment niet doorzoekbaar door zoekmachines. Daardoor blijft veel informatie ontoegankelijk. Relatief eenvoudige vragen als ‘Wat is de beste treinreis van Enschede naar Amsterdam op 4 juni 2012?’ en ‘Wat is het telefoonnummer van Djoerd Hiemstra uit Enschede?’ kunnen niet door zoekmachines als Google en Bing worden beantwoord kunnen worden. Toch is het antwoord daarvan wel degelijk beschikbaar op het web. Namelijk in het diepe web, waar zoekmachines niet kunnen komen omdat ze de pagina’s niet van te voren hebben gedownload. De redenen daarvoor zijn divers en de Universiteit Twente onderzoekt methoden waarmee deze informatie toch gevonden kan worden door vragen op juiste te interpreteren, vragen naar de juiste bron te sturen en zoekresultaten te interpreteren en te integreren met resultaten van andere bronnen. De eerste demonstratie van onderzoeksresultaten uit dit onderzoek ( kreeg sinds begin 2012 al 10.000den bezoekers.

Keynote lecture by Jimmy Lin at Big Data tutorial

Tuesday, October 18th, 2011, posted by Djoerd Hiemstra

Jimmy Lin will give a keynote lecture at the SIKS/BigGrid Big Data tutorial that preceeds the DBDBD on 30 November and 1 December 2011. Dr. Lin, who holds a PhD from MIT, is associate professor in the iSchool at the University of Maryland. He also has appointments in the Institute for Advanced Computer Studies (UMIACS) and the Department of Computer Science at Maryland. Lin works at the intersection of natural language processing (NLP) and information retrieval (IR), with a recent emphasis on scalable algorithm design and large-data issues. He directs the recently-formed Cloud Computing Center, an interdisciplinary group which explores the many aspects of cloud computing as it impacts technology, people, and society. He is also a member of both the Computational Linguistics and Information Processing Lab (CLIP) and the Human-Computer Interaction Lab (HCIL). Lin worked on Cloudera, which aims to bring Hadoop MapReduce to the enterprise, and is currently spending a sabbatical at Twitter

ImagePile: an Alternative for Vertical Results Lists

Tuesday, May 17th, 2011, posted by Djoerd Hiemstra

ImagePileRecent work shows that children are very well capable of searching with Google, due to their familiarity with the interface. However, children do have difficulties with the vertical list representation of the results. In this paper, we present an alternative result representation for a touch interface, the ImagePile. The ImagePile displays the results as a pile of images where the user navigates through via horizontal swiping. This representation was tested on a search engine for the Emma child hospital’s library. Using a within subject experiment, both representations were tested with children to compare the usability of both systems. The vertical representation was perceived as easier to use, but the ImagePile system was considered more fun to use. Also, with the ImagePile system more relevant results were chosen by the children, and they were more aware of the number of results.

Guest lecture by Peter Dickman from Google

Tuesday, November 16th, 2010, posted by Djoerd Hiemstra

Friday 26 November, Peter Dickman from Google will talk about Google’s infrastructure. The lecture will start at 10:30 h. (so 15 minutes earlier than usual) in RA-1501.

This a rapid overview of the approach Google uses to develop and offer global products. I will briefly (and somewhat superficially) cover the whole of our infrastructure from physical systems, such as the data centers, through the software stack to our software development methodology and the corporate engineering culture that both builds and utilizes the infrastructure.

Peter Dickman is an engineering manager in Google’s main European engineering centre in Zurich. He is involved with both the internals of the Google search engine and projects to protect user data in Google’s systems. Prior to working at Google, Peter was an academic in the UK, researching large-scale distributed systems (though on arrival at Google he discovered what large really meant).
