Abstract
Scientific research of English language education presupposes efforts to define terms as precisely as possible. The development of a thesaurus is one of the efforts for normalizing or controlling the language used in this field. In addition, recent technical innovations have made the store of a huge amount of research data possible through computers. Efficient retrieval of this information needs a controlling of the terminology employed in the subject field. Therefore it is necessary to construct a thesaurus which represents the keywords in the field and also shows how these keywords are related to each other. The purpose of this paper is to present a draft form of a thesaurus on English language education, to explain its construction process and to discuss several problems to be resolved.
