Optimizing Search Engines using Clickthrough Data

by Thorsten Joachims , 2002
"... This paper presents an approach to automatically optimizing the retrieval quality of search engines using clickthrough data. Intuitively, a good information retrieval system should present relevant documents high in the ranking, with less relevant documents following below. While previous approaches ..."

function of a meta-search engine to a particular group of users, outperforming Google in terms of retrieval quality after only a couple of hundred training examples.

The anatomy of a large-scale hypertextual web search engine.

by Sergey Brin , Lawrence Page - Comput. Netw. ISDN Syst., , 1998
"... Abstract In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a fu ..."

Internet Advertising and the Generalized Second Price Auction: Selling Billions of Dollars Worth of Keywords

by Benjamin Edelman, Michael Ostrovsky, Michael Schwarz - AMERICAN ECONOMIC REVIEW , 2007
"... We investigate the “generalized second-price” (GSP) auction, a new mechanism used by search engines to sell online advertising. Although GSP looks similar to the Vickrey-Clarke-Groves (VCG) mechanism, its properties are very different. Unlike the VCG mechanism, GSP generally does not have an equilib ..."

Learning to rank using gradient descent

by Chris Burges, Tal Shaked, Erin Renshaw, Matt Deeds, Nicole Hamilton, Greg Hullender - In ICML , 2005
"... We investigate using gradient descent methods for learning ranking functions; we propose a simple probabilistic cost function, and we introduce RankNet, an implementation of these ideas using a neural network to model the underlying ranking function. We present test results on toy data and on data f ..."

Learning object categories from google’s image search

by R. Fergus, L. Fei-fei, P. Perona, A. Zisserman - In Proceedings of the International Conference on Computer Vision , 2005
"... Current approaches to object category recognition require datasets of training images to be manually prepared, with varying degrees of supervision. We present an approach that can learn an object category from just its name, by uti-lizing the raw output of image search engines available on the Inter ..."

on the Internet. We develop a new model, TSI-pLSA, which extends pLSA (as applied to visual words) to include spa-tial information in a translation and scale invariant man-ner. Our approach can handle the high intra-class vari-ability and large proportion of unrelated images returned by search engines. We

Internet traffic engineering by optimizing OSPF weights

by Bernard Fortz - in Proc. IEEE INFOCOM , 2000
"... Abstract—Open Shortest Path First (OSPF) is the most commonly used intra-domain internet routing protocol. Traffic flow is routed along shortest paths, splitting flow at nodes where several outgoing links are on shortest paths to the destination. The weights of the links, and thereby the shortest pa ..."

The Google similarity distance

by Rudi Cilibrasi, Paul M. B. Vitányi , 2005
"... Words and phrases acquire meaning from the way they are used in society, from their relative semantics to other words and phrases. For computers the equivalent of ‘society ’ is ‘database, ’ and the equivalent of ‘use ’ is ‘way to search the database. ’ We present a new theory of similarity between ..."

words and phrases based on information distance and Kolmogorov complexity. To fix thoughts we use the world-wide-web as database, and Google as search engine. The method is also applicable to other search engines and databases. This theory is then applied to construct a method to automatically extract

Agglomerative Clustering of a Search Engine Query Log

by Doug Beeferman, Adam Berger - In Proceedings of the sixth ACM SIGKDD International Conference on Knowledge Discovery and Data Mining , 2000
"... This paper introduces a technique for mining a collection of user transactions with an Internet search engine to discover clusters of similar queries and similar URLs. The information we exploit is "clickthrough data": each record consists of a user's query to a search engine along wi ..."
