There is a crucial need for tools that allow effective analysis of search engine queries to provide a greater understanding of Web users' information seeking behavior. The objective of the study is to develop an effective strategy for the selection of samples from large-scale data sets. Millions of queries are submitted to Web search engines daily and new sampling techniques are required to bring these databases to a manageable size, while preserving the statistically representative characteristics or the entire data set. This paper reports results from a study using data logs from the Excite Web search engine, We use Poisson sampling to develop a sampling strategy. and show how sample sets selected by Poisson sampling statistically effectively represent the characteristics of the entire dataset. In addition, this paper discusses the use of Poisson sampling in continuous monitoring of stochastic processes, such as Web site dynamics.eninfo:eu-repo/semantics/closedAccessComputer scienceInformation science & library sciencePoisson samplingUsersLarge-scale in depth data analysisWeb user modelingSearch engine queriesData miningArticle0001754791000022-s2.0-0036643012473490384Computer scienceInformation systemsInformation science & library science
