trie is an ordered tree structure with a character on each edge. The trie provides an efficient management of a keyword set in natural language processing, information retrieval systems and so on. The double-array with a high-speed performance has been proposed to represent the trie efficiently. As its space usage depends on the number of trie nodes, the space usage decreases by reducing nodes. To reduce the number of trie nodes, a Minimal-Prefix (MP) trie and a Directed Acyclic Word Graph (DAWG) have been proposed, and the double-array can represent the data structures efficiently. On the other hand, the data structures include many nodes that can be reduced by giving a string label to each edge. However, the double-array with the string labels have not been proposed. This paper proposes a new double-array structure with the string labels by using multiple arrays depending on label sizes. Moreover, we show its effectiveness by experiments.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告アルゴリズム（AL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicVolumeNumber":"2015-AL-153"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
