Therefore, we extracted short writing pieces from the International Corpus of Japanese as a econd Language (I-JAS) and prepared text sets of different sizes (n = 10, n = 20, n = 30, n = 40, and n = 50) for Chinese and Korean learners of Japanese as well as Japanese native speakers. We then examined the difference  ratios observed across five kinds of text sets with a focus on basic linguistic indices, such as the total number of tokens per texts, and frequencies of punctuation marks, nouns and verbs, and conjugation forms of verbs. Our analyses show that the influence of sample size is not as strong as generally expected, and that discussion of learners’ L2 production with a relatively smaller corpus data could be rationalized to some extent.","subitem_description_type":"Other"}]},"item_10003_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15084/00001516","subitem_identifier_reg_type":"JaLC"}]},"item_10003_publisher_45":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立国語研究所"}]},"item_10003_relation_40":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"言語資源活用ワークショップ2017"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://pj.ninjal.ac.jp/corpus_center/lrw2017.html","subitem_relation_type_select":"URI"}}]},"item_10003_version_type_44":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石川, 慎一郎"},{"creatorName":"イシカワ, シンイチロウ","creatorNameLang":"ja-Kana"},{"creatorName":"ISHIKAWA, Shin'ichiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-15"}],"displaytype":"detail","filename":"LRW-2017-18-O-B-2.pdf","filesize":[{"value":"944.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"LRW-2017-18-O-B-2.pdf","url":"https://repository.ninjal.ac.jp/record/1532/files/LRW-2017-18-O-B-2.pdf"},"version_id":"0cb41586-0432-4c0e-bdf3-cdf006ddeaf1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"多言語母語の日本語学習者横断コーパス(I-JAS)","subitem_subject_scheme":"Other"},{"subitem_subject":"International Corpus of Japanese as a Second Language (I-JAS)","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"学習者コーパス研究における標本数の問題","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"学習者コーパス研究における標本数の問題"},{"subitem_title":"A Reconsideration of the Needed Sample Size in Learner Corpus Studies","subitem_title_language":"en"}]},"item_type_id":"10003","owner":"3","path":["246"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-20"},"publish_date":"2018-03-20","publish_status":"0","recid":"1532","relation_version_is_last":true,"title":["学習者コーパス研究における標本数の問題"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T10:23:53.779738+00:00"}
