Event-Driven Query Expansion [PDF]
Proceedings of the 14th ACM International Conference on Web Search and Data Mining, 2020 A significant number of event-related queries are issued in Web search. In this paper, we seek to improve retrieval performance by leveraging events and specifically target the classic task of query expansion. We propose a method to expand an event-related query by first detecting the events related to it.

Toward personalized query expansion [PDF]
Proceedings of the Second ACM EuroSys Workshop on Social Network Systems, 2009 Social networking and tagging have taken off at an unexpected scale and speed, opening huge opportunities to enhance the user search experience. We present Gossple, a new, user-centric, approach to improve the exploration of the Internet. Underlying \textsc{Gossple} lies the intuition that while social networks provides news from your old buddies, you ...
