Congratulations to my PhD student Daan Odijk for winning the CIKM 2015 best student paper award for his paper “Struggling and Success in Web Search’. This full paper is the result of Daan’s internship at Microsoft Research in Redmond in 2014. In this joint paper by Daan Odijk, Ryen White, Ahmed Hassan Awadallah and Susan Dumais, the authors investigate why some web searchers succeed where others struggle.
