GikiCLEF Topics and Wikipedia Articles: Did They Blend?

This paper presents a post-hoc analysis on how the Wikipedia collections fared in providing answers and justifications to GikiCLEF topics. Based on all solutions found by all GikiCLEF participant systems, this paper measures how self-sufficient the particular Wikipedia collections were to provide answers and justifications for the topics, in order to better understand the recall limit that a GikiCLEF system specialised in one single language has.
