Counterfactual Estimation and Optimization of Click Metrics in Search Engines

Lihong Li, Shunbao Chen, Jim Kleban, Ankur Gupta
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
The key challenge is the counterfactual nature: in the case of Web search, any change to a component of the search engine may result in a different search result page for the same query, but we normally  ...  Consequently, it appears impossible to accurately estimate online metrics that depend on user feedback, unless the new engine is actually run to serve live users and compared with a baseline in a controlled  ...  For a given spelling correction algorithm, the user's satisfaction can be measured by modeling how the user interacted with the search engine on a real search session.  ...

Effective Time Ratio: A Measure for Web Search Engines with Document Snippets [chapter]

Jing He, Baihan Shu, Xiaoming Li, Hongfei Yan
2010 Lecture Notes in Computer Science  
We further deploy a real user study, showing that effective time ratio can reflect users' satisfaction better than the existing metrics based on document relevance and/or snippet relevance.  ...  Effective time ratio measures the ratio between effective time a user spent on getting relevant information and the total search time.  ...  Some researchers even states that recall is not well founded as a measure of satisfaction [9] . Therefore, precision and its extensions are very important in Web search engine evaluation.  ...

First 20 precision among World Wide Web search services (search engines)

H. Vernon Leighton, Jaideep Srivastava
1999 Journal of the American Society for Information Science  
All searching was done from January 31 to March 12, 1997. In the study, steps are taken to ensure that bias has not unduly influenced the evaluation.  ...  Five search engines, Alta Vista, Excite, HotBot, Infoseek, and Lycos, are compared for precision on the first 20 results returned for 15 queries, adding weight for ranking effectiveness.  ...  I would like to thank the reviewers for their advice and suggestions.  ...

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 this paper, we propose and evaluate a framework that maximizes users' search effectiveness by directing them to the engine that yields the best results for the current query.  ...  INTRODUCTION Web search engines such as Google, Yahoo!, and Live Search provide users with keyword access to Web content.  ...

User Evaluation and Metrics Analysis of a Prototype Web-Based Federated Search Engine for Art and Cultural Heritage

Minas Pergantis, Iraklis Varlamis, Andreas Giannakoulopoulos
2022 Information  
This paper presents the process of designing and developing a Federated Search Engine (FSE) that collects such content from multiple credible sources of the world of Art and Culture and presents it to  ...  Content and metadata concerning a specialized field such as Art and Cultural Heritage are often scattered throughout the World Wide Web, making it hard for end-users to find, especially amid the vast and  ...  In order for someone to find information, they need to enter a web query into the search engine. A web query consists of one or more search terms.  ...

Auditing Search Engines for Differential Satisfaction Across Demographics

Rishabh Mehrotra, Ashton Anderson, Fernando Diaz, Amit Sharma, Hanna Wallach, Emine Yilmaz
2017 Proceedings of the 26th International Conference on World Wide Web Companion - WWW '17 Companion  
We then propose three methods for measuring latent differences in user satisfaction from observed differences in evaluation metrics.  ...  We first explain the pitfalls of na\"ively comparing the behavioral metrics that are commonly used to evaluate search engines.  ...  One way to assess whether a search engine provides equal access is to look for differences in user satisfaction across demographic groups.  ...

Search Engine Query Clustering Using Top-k Search Results

Yuan Hong, Jaideep Vaidya, Haibing Lu
2011 2011 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
We propose a novel similarity metric for diverse queries based on the ranked URL results returned by a search engine for queries.  ...  However, clustering search queries effectively is quite challenging, due to the high diversity and arbitrary input by users.  ...  Out of this morass of data, users typically search for the relevant information that they want by posing search queries to search engines.  ...
