| Abstract(in English) | A trie is one of the method for key search algorithm and utilized in natural language processing and so on. It is represented by a double array and LOUDS. The double array provides fast retrieval at time complexty of O(1), but its space usage is larger than that of LOUDS. LOUDS is a succinct data structure using bit-vector. Its space usage is extremely compact, but its retrieval speed is not so fast. This paper presents a compression method of the double array using approximate straight lines. Prom simulation results for 200,000～1,000,000 keys, it turned out that the space usage of the presented method becomes about 60% compared with the double array and its retrieval speed is about twelve times faster than that of LOUDS. |
