This problem subsumes many interesting personalized web applications such as personalization for buzz query detection, for query expansion, and for query recommendation. These personalized applications can greatly enhance user interaction with web search engines by providing more customized information discovered from user input (i.e., queries), but the LQP task has rarely been investigated in the literature. Although exist abundant work on estimating\n            <jats:italic>global<\/jats:italic>\n            web search trends does exist, it often encounters the big challenge of data sparsity when personalization comes into play.\n          <\/jats:p>\n          <jats:p>In this article, we tackle the LQP task by proposing a series of collaborative language models (CLMs). CLMs alleviate the data sparsity issue by collaboratively collecting queries and trend information from the other locations. The traditional statistical language models assume a fixed background language model, which loses the taste of personalization. In contrast, CLMs are personalized language models with flexible background language models customized to various locations. The most sophisticated CLM enables the collaboration to adapt to specific query topics, which further advances the personalization level. An extensive set of experiments have been conducted on a large-scale web query log to demonstrate the effectiveness of the proposed models.<\/jats:p>","DOI":"10.1145\/2622617","type":"journal-article","created":{"date-parts":[[2014,7,1]],"date-time":"2014-07-01T14:23:02Z","timestamp":1404224582000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Collaborative Language Models for Localized Query Prediction"],"prefix":"10.1145","volume":"4","author":[{"given":"Yi","family":"Fang","sequence":"first","affiliation":[{"name":"Santa Clara University, Santa Clara, California"}]},{"given":"Ziad Al","family":"Bawab","sequence":"additional","affiliation":[{"name":"Microsoft, Sunnyvale, California"}]},{"given":"Jean-Francois","family":"Crespo","sequence":"additional","affiliation":[{"name":"Google, California"}]}],"member":"320","published-online":{"date-parts":[[2014,6]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1242572.1242595"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2339530.2339594"},{"volume-title":"Pattern recognition and machine learning","author":"Bishop C.
