represents an ordered tree called “trie”, and provides fast retrieval in the trie. Recently, many compact representations of the double-array have been proposed because a compact data structure is important in big data. The double-array provides inorder (from a parent to a child) and reverse (from a child to a parent) traversals, but the compact representations provide only the inorder traversal. Therefore, the compact representations don't have a dynamic update and a reverse lookup in the double-array. This paper proposes a compact array structure with the reverse traversal. In addition, experimental results show that the new structure represents the trie with 36% of the double-array size.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告情報基礎とアクセス技術（IFAT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-07-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2015-IFAT-119"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
