ABSTRACT
Maps Auto-complete is an essential service complementing the functionality of map search engines. It allows users to formulate their queries faster and also provides better query formatting, which increases the chance of returning a relevant search result.
Intuitively, the engagement with the service depends primarily on the quality of the suggestions it recommends. We notice, however, an interesting phenomenon that has not received much attention previously - often Auto-complete correctly identifies the most relevant suggestion, yet users do not click on it right away, if at all. Here we reason over the causes for the phenomenon, provide empirical evidence, and then propose a mitigation based on query expansion. Two models are proposed which generate word or phrase query expansions, allowing users to reach faster a 'mental pause' during which they are more likely to engage with the Auto-complete suggestions. Evaluation of the models is presented.

Examining the effectiveness of real-time query expansion
Interactive query expansion (IQE) (c.f. [Efthimiadis, E. N. (1996). Query expansion. Annual Review of Information Systems and Technology, 31, 121-187]) is a potentially useful technique to help searchers formulate improved query statements, and ...
Query suggestions in the absence of query logs
SIGIR '11: Proceedings of the 34th international ACM SIGIR conference on Research and development in Information RetrievalAfter an end-user has partially input a query, intelligent search engines can suggest possible completions of the partial query to help end-users quickly express their information needs. All major web-search engines and most proposed methods that ...
Query completion in community-based Question Answering search
AbstractQuery completion has long been proved useful to help a user explore and express his information need. In general search, such completions can be generated from a large scale query log and other accessory information. However, without ...
