As an application\npossibility to management research and management practice,\nimprovement of natural language processing technology in recent years,\nespecially progressive technology concerning distributed representation,\ncan be said to be a fully usable technology.\nAnd, it is not a direct competition relationship like a smartphone and a\ndigital camera, www (world wide web) and a book, which is a threat of\nsubstitute in Porter’s 5force analysis, that is, competitive relations beyond\nproduct categories are topics.\nIn this paper, we consider a recent social change and propose a method\nto analyze and visualize competing relationships beyond the categories of\ngoods and services by machine mining using machine learning (AI)\ntechnology. The method of text mining adopted by this paper is not based\non aggregate values such as mainstream current weighing text analysis\nbut based on the distributed representation of words calculated by\nmachine learning (fasttext). Therefore, the basis of the analysis is not the\nsum of the words in the text but the similarity using the distributed\nrepresentation of the word. Text mining based on distributed\nrepresentation is still an incomplete technology and it is not a fixed\nmethod, it is a field where further development is expected in the future.\nIn this paper, we propose two analytical methods using this distributed\nrepresentation.\nThe method proposed by this paper is useful for business researchers,\nalso for practitioners, when planning and model change of products/\nservices, comparison with other company’s product services becomes\neasier than ever, more detailed analysis.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"桃山学院大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00240555","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02869721","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"竹岡, 志朗"},{"creatorName":"タケオカ, シロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKEOKA, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1106","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-28"}],"displaytype":"detail","filename":"101_竹岡志朗.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"竹岡志朗","url":"https://stars.repo.nii.ac.jp/record/8915/files/101_竹岡志朗.pdf"},"version_id":"7c46dfbb-94cc-4baa-bafe-9f8c1bd74792"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"機械学習","subitem_subject_scheme":"Other"},{"subitem_subject":"分散表現","subitem_subject_scheme":"Other"},{"subitem_subject":"テキストマイニング","subitem_subject_scheme":"Other"},{"subitem_subject":"fasttext","subitem_subject_scheme":"Other"},{"subitem_subject":"クチコミ","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"機械学習を活用したテキストマイニング : クチコミを用いた商品・サービスカテゴリーの横断分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"機械学習を活用したテキストマイニング : クチコミを用いた商品・サービスカテゴリーの横断分析"},{"subitem_title":"Text Mining using Machine Learning : Cross-sectional Analysis of Products／Service Categories using Reviews","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"13","path":["1780"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-02-28"},"publish_date":"2018-02-28","publish_status":"0","recid":"8915","relation_version_is_last":true,"title":["機械学習を活用したテキストマイニング : クチコミを用いた商品・サービスカテゴリーの横断分析"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-05-15T14:58:36.530182+00:00"}
