Regional Effects on Query Reformulation Patterns

Jesper, Steph; Clough, Paul and Hall, Mark (2013). Regional Effects on Query Reformulation Patterns. In: Research and Advanced Technology for Digital Libraries (Aalberg, Trond; Papatheodorou, Christos; Dobreva, Milena; Tsakonas, Giannis and Farrugia, Charles J. eds.), Lecture Notes in Computer Science, Springer, Berlin, Heidelberg, pp. 382–385.



This paper describes an in-depth study of the effects of geographic region on search patterns; particularly query reformulations, in a large query log from the UK National Archives (TNA). A total of 1,700 sessions involving 9,447 queries from 17 countries were manually analyzed for their semantic composition and pairs of queries for their reformulation type. Results show country-level variations for the types of queries commonly issued and typical patterns of query reformulation. Understanding the effects of regional differences will assist with the future design of search algorithms at TNA as they seek to improve their international reach.
