ABSTRACT
Many of today's search engines provide autocompletion while the user is typing a query string. This type of dynamic query suggestion can help users to formulate queries that better represent their search intent during Web search interactions. In this paper, we demonstrate our query suggestion system called CONQUER, which allows to efficiently suggest queries for a given partial query and a number of available query context observations. The context-awareness allows for suggesting queries tailored to a given context, e.g., the user location or the time of day. CONQUER uses a suggestion model that is based on the combined probabilities of sequential query patterns and context observations. For this, the weight of a context in a query suggestion can be adjusted online, for example, based on the learned user behavior or user profiles. We demonstrate the functionality of CONQUER based on 6 million queries from an AOL query log using the time of day and the country domain of the clicked URLs in the search result as context observations.

Interrogation Based on Semantic Annotations: Context-Based Construction of Formal Queries from Keywords
Traditional information search approaches do not explicitly capture the meaning of a keyword query, but provide a good way for the user to express his or her information needs based on the keywords. In principle, semantic search aims to produce better ...
Situational Context for Ranking in Personal Search
WWW '17: Proceedings of the 26th International Conference on World Wide WebModern search engines leverage a variety of sources, beyond the conventional query-document content similarity, to improve their ranking performance. Among them, query context has attracted attention in prior work. Previously, query context was mainly ...
Using query context models to construct topical search engines
IIiX '10: Proceedings of the third symposium on Information interaction in contextToday, if a website owner or blogger wants to provide a search interface on their web site, they have essentially two options: web search or site search. Site search is often too narrow and web search often too broad. We propose a context-specific ...
