1. A system for transforming content of an electronic document from a non-Romanized native language to a Romanized language, the system comprising one or more processors and memory to store program code that, when executed by the one or more processors, causes the one or more processors to: identify within the native language document one or more references, in the native language, to entities having Romanized language names; generate a preprocessed version of the native language document in which the identified references to entities having Romanized language names are replaced by the Romanized language names and corresponding tags that specify the Romanized language names as named entities; and translate the preprocessed version of the native language document into a Romanized-language output document, maintaining the Romanized language names in the output document and applying the Romanized language names and corresponding tags as context for disambiguating remaining native language expressions in the preprocessed version of the native language document.
