Some of the victims of Nazi prosecution have consigned their personal experiences in the form of diaries of their internment in concentration camps. Such human-centric texts may contrast with the organisation of knowledge about such events that, for example, historians and archivists make. In this work, we analyse six such narrations with the use of Entity Extraction and Named Entity Recognition techniques, present the results of the corresponding exploration, and discuss the suitability of such tools on this corpus. We show that knowledge tools, that have been successfully used to organise documents, can be lacking when describing personal accounts, and we suggest ways to alleviate this.
