Named entity recognition aims to classify words in a document into pre-defined target entity classes.It is now considered to be fundamental for many natural language processing tasks such as information retrieval, machine translation, information extraction and question answering.This paper presents a workflow to build an English-Vietnamese named entity corpus from an aligned bilingual corpus.The workflow is based on a state of the art named entity recognition tool to identify English named entities and map them into Vietnamese text.The paper also presents a detailed discussion about several mapping errors and differences between English and Vietnamese sentences that affect this task.
