    摘要: A recovery method for a high-dimensional index structure is disclosed, in which a reinsert operation is employed based on ARIES (algorithm for recovery and isolation exploiting semantics) and a page-oriented redo and a logical undo. Further, a recording medium on which a program for carrying out the above method is recorded is disclosed, the program being readable by a computer. The recovery method for a high-dimensional index structure employing a reinsert operation according to the present invention includes the following steps. At a first step, an entry is inserted into a node, a minimum bounding region is adjusted, an overflow is processed, and a log record is stored. At a second step, the log record thus stored is recovered.

    摘要: A bulk loading method, for use in a high-dimensional index structure using some parts of dimensions based on an unbalanced binarization scheme, accelerates an index construction and improves a search performance. For the purpose, the bulk loading method calculates a topology of the index by recognizing information for the index to be constructed using a given data set, splits the given data set into sub-sets of data by repeatedly performing an establishment of a split strategy and a binarization based on the calculated topology of the index, if a leaf node is derived from the sub-sets of data divided through a top-down recursive split process, reflects a minimum bounding region of the leaf node on a higher node, and, if a non-leaf node is generated, repeatedly performing the above processes for another sub-set of data to thereby produce a final root node.

    摘要: An insertion method in a high-dimensional index structure for a content-based image retrieval is disclosed, in which a desired image can be efficiently searched when there is formed a high-dimensional image database. In the present invention, the basic properties of the CIR tree are utilized, and at the same time, a splitting algorithm having a superior search efficiency over the conventional CIR tree is employed. Further, an effective standard for choosing lower nodes is provided, and a re-insertion algorithm capable of re-inserting based on a weighted center is employed, thereby forming an ECIR (Extended CIR) as a high-dimensional index structure supporting efficient retrieval performance. That is, a splitting algorithm for the branch nodes and the terminal nodes are adopted so as to improve the efficiency when carrying out the search and insertion. The re-insertion objects are chose based on the weighted center when the nodes overflow. According to the present invention, the images can be efficiently searched when an image information containing many feature dimensions is formed into a database.

    摘要: A cache coherency maintenance system and method of a user file manager in an object-based storage system are provided. According to the cache coherence maintenance system and method, by maintaining the coherency of a writeback cache based on time using a timer, metadata and data information are efficiently managed. Accordingly, even when accesses by users increase, the cost of maintaining the coherency of the cache is distributed to respective user file managers. In this way the performance of the entire object-based storage system is enhanced and the consistency and efficiency of information increase.
