  • Composite names. Composite names or complex named entities consist of two or more words. Frequently, appositions are considered to be a part of a name. For example, there is no need for the translation of the word “mount” in “Mount Cook”, but “Insel” is typically translated in the expression “Insel Sylt”/“island of Sylt”. For NER, certain rules have to be established how composite names are normalized. In some composite names, two or more toponyms (geographic names) are employed in reference to a single entity, e.g. “Frankfurt/Oder” or “Haren (Ems)”. While additional toponyms in a context allow for a better disambiguation, such composite names require a normalization, too.
