Compressed Full-text Indexes for DNA Sequences

Abstract (in Japanese) (See Japanese page) 
(in English) A problem of processing large-scale data is the amount of space to store data
and the size of data structures for efficient search.
To solve the problem, succinct data structures have been proposed,
which can store data structures in a compressed form, while supporting various
queries in the same time complexities. Succinct data structures are
therefore suitable for processing large-scale data.
On the contrary, operation speed on an actual computer becomes considerably
low-speed. In this paper, a succinct data structure for searching
DNA sequences is proposed. Its query speed is fast; if the same amount
of memory is used, its query speed is 10 times faster than other methods,
and its memory usage is half of them to achieve the same query speed.
