Modeling actions of PubMed users with n-gram language models

Jimmy Lin, W. John Wilbur
2008 Information retrieval (Boston)  
We encode user actions as string sequences and model these sequences using n-gram language models. The models are evaluated in terms of perplexity and in a sequence prediction task.  ...  Unlike most previous studies on general Web search, our work examines user activities with a highly-specialized search engine.  ...  Open Access This article is distributed under the terms of the Creative Commons Attribution Noncommercial License which permits any noncommercial use, distribution, and reproduction in any medium, provided  ...

Search Result Prefetching Using Cursor Movement

Fernando Diaz, Qi Guo, Ryen W. White
2016 Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval - SIGIR '16  
Balancing the costs in prefetching particular results against the benefits in reduced latency to searchers represents the search result prefetching challenge.  ...  We present methods that leverage searchers' cursor movements on search result pages in real time to dynamically estimate the result that searchers will request next.  ...  In the current implementation, we optimize our client-side code to ensure no significant delay on PLT for SERPs with the logging enabled.  ...

Modeling dwell time to predict click-level satisfaction

Youngho Kim, Ahmed Hassan, Ryen W. White, Imed Zitouni
2014 Proceedings of the 7th ACM international conference on Web search and data mining - WSDM '14  
Clicks on search results are the most widely used behavioral signals for predicting search satisfaction. Even though clicks are correlated with satisfaction, they can also be noisy.  ...  We show that the topic of the page, its length and its readability level are critical in determining the amount of dwell time needed to predict whether any click is associated with satisfaction.  ...  ., client side monitoring rather than server side as reported here), study other factors that may affect click dwell time (e.g., pages revisited by the same user may lead to lower dwell times given increased  ...

Enhancing web search by promoting multiple search engine use

Ryen W. White, Matthew Richardson, Mikhail Bilenko, Allison P. Heath
2008 Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '08  
Any given Web search engine may provide higher quality results than others for certain queries. Therefore, it is in users' best interest to utilize multiple search engines.  ...  In contrast to prior work on meta-search, we do not advocate for replacement of multiple engines with an aggregate one, but rather facilitate simultaneous use of individual engines.  ...  The logs gave us access to user interactions with all search engines. From these logs, we extracted search sessions that began with a query to Google, Yahoo!  ...
