For the development of Chinese dictionary and the efficiency of Chinese learning, evaluation and study of Chinese dictionary are essential. However, there are no standards and models for Chinese dictionary evaluation in Korea, so it was difficult to conduct systematic evaluation of Chinese dictionary. Accordingly, this paper assessed the microstructure of 『Naver Dictionary』, which is currently used by domestic Chinese learners, for the purpose of improving the quality of domestic online Chinese learner’s dictionaries. Using the evaluation items prepared by Mi-Hyang Lee (2019), and the overall composition of the microstructure was evaluated to see if the 『Naver Dictionary』 appropriately organizes and provides necessary information as an online Chinese learner’s dictionary, and was assessed whether each information item in the microstructure provided the exact information to be provided. As a result of the evaluation, the vocabulary grade and semantic distribution item were the best to be able to answer ‘yes’ to all questions, and the overall composition, definition of a word, and example items of the microstructure were also relatively positive. On the other hand, items of spelling, pronunciation, part-of-speech, grammatical information, and pragmatic information were evaluated as necessary for modification and supplementation. The 『Naver Dictionary』 is an bilingual dictionary, which has items that must be equipped with a microstructure, but found errors in the intonation notation in the pronunciation item, and errors in providing wrong target word with wrong part-of-speech notation were found in the item of definition of a word. 『Naver Dictionary』 is a learning dictionary, which shows the vocabulary grade that users can easily recognize in the headword and provides useful information for Chinese learning. The function as a learning dictionary was prominent in the reference words item. However, it is necessary to supplement the fact that spelling information is not provided, the example is not provided separately by the semantic terms of the headword, the grammar and pragmatic information is not sufficient, and the irregular changes of the intonation and the inconsistency of the special vocabulary. 『Naver Dictionary』 is an online dictionary, which is convenient for viewing microstructures and provides various information through services utilizing online characteristics. In particular, the advantages of online dictionaries have been prominent in the example item. However, It was regrettable that the online dictionary, which has no limit on capacity, did not provide more information as a learning dictionary, such as collocation and syntactic information, precautions on grammar and pragmatic use, discourse usage, and cultural knowledge, etc. This study can be used to evaluate and modify other online foreign language learning dictionaries, and can be used to modify and update online Chinese dictionaries.
