WikiBiography is a corpus of about 1200 annotated biographies from the German version of Wikipedia. Fully automatic preprocessing includes the following:
* there is only one coreference chain which links all mentions of the biographee. The annotation is done with freely available software (see references). To visualize the data and access and correct the annotation you should use MMAX2. With MMAX2 API you can access any layer of annotation from your Java programs.
Orange and green fonts are used for temporal expressions (e.g. “7. Oktober 1885”, “später”) and locations (e.g. “Kopenhagen”, “Dänemarks”) respectively. People other than the biographee (e.g. “Chtistian Bohr”, “Harald Bohr”) are highlighted with light-blue. Mentions of the biographee are highlighted with red (e.g. “Niels Henrik David Bohr”, “er”, “Niels Bohr”). The annotation of a selected word (e.g. “Professor”) is displayed in a separate window. The head of the word is highlighted with grey colour then and an ark from the dependent word to its head is displayed.

A list of about 300 connectives from IDS Mannheim is used to identify these connectives in our corpus.
Temporal expressions are identified with a set of templates. Named entities are classified as person, location or organization based on the information from Wikipedia.
