Name ambiguity of authors is a long-standing challenge in Digital Libraries. Simple
string searches for authors often have unsatisfactory results: publications by the
author in which their name is written differently cannot be found, and publications
by other authors of the same name get included. The authors can be distinguished
with the use of persistent identifers. This improves the search function and also
contributes to the data linking process. But many catalogs of libraries are not fully
disambiguated and it is not feasible for big libraries like the ZBW - Leibniz Information
Centre for Economics to disambiguate the bibliographic records manually.
The goal of this work is to help the ZBW with their disambiguation task. For
this purpose I analysed the datasets of the ZBW and identifed the challenges that
need to be overcome. I proposed an approach which uses already disambiguated
records to assign persistent identifer to ambiguous author references. The approach
could disambiguate ambiguous author references, though the quality of the
method needs to be further evaluated.:List of Figures
