Abstract: A file list generation device creates, at high speed, a list of added, changed, or deleted file data by acquiring the directory URLs of search target files from a first storage, counting the number of directories in each layer through analysis of the directory URLs, and, based on the result of the counting, determines a dividing policy to divide a scan target directory scanning operation, which is to be performed with a distributed server cluster. Directories of the search target files are divided in accordance with the determined dividing policy, and a snapshot of a current directory tree is acquired.

Abstract: A file list generation method of the present invention includes: a first step of acquiring, from a file server, an operation history list showing additions, changes, and deletions performed on file data in a search target file after the last search index creating operation, the file server managing the search target file; and a second step of, when more than one operation history about a single file is included in the acquired operation history list, obtaining only the latest operation histories and then consolidating the operation histories and operation histories of the other files, and outputting the consolidated list as a difference list showing the differences from the history list of operations performed on the search target file after the last search index creating operation.

Abstract: Each of a dynamic image delivering server A 132 and a dynamic image delivering server B 133 delivers a plurality of contents list data and a dynamic image designated by each contents list data. A transcoding server 131 acquires prescribed contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, and stores them in a storage device. Then, the transcoding server 131 acquires the dynamic image designated by the acquired contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, converts the acquired dynamic image to a format of the dynamic image regenerable on a player 111, and stores the converted dynamic image in the storage device. Upon request from the player 111, the transcoding server 131 retrieves a contents list data and/or a dynamic image from the storage device, and transmits them to the player 111.

Abstract: Erroneous deletion of data due to a collision of digest information during data de-duplication using digest information is prevented. When backup data is stored on a backup server 1100, digest information of the backup data is generated and stored in a digest information management table 4200. In addition, when a backup data storage request is made to the backup server 1100, a digest information verification control sub-program 1127 generates digest information of data to be backed up, and performs verification against the digest information of the backed up data already stored on the backup server 1100. If, by this verification, it is found that backed up data having the same digest information is already stored, de-duplication is realized by reusing the existing backed up data without newly storing the data to be backed up.

Abstract: A file scan process is carried out, in parallel in a distributed manner, on a file server for which indices have been created once, to create a list of added, changed, or updated files. A file list of indexed scan target files is created by a distributed processing server. Directory URLs of the scan target files are acquired from the file list and analyzed to count a number of directories in each layer and determine a division unit for division of a scan process to be carried out on the scan target directories, based on a result of the counting.

Abstract: Provided is a technique of correcting influences of optical environment to correctly recognize the color of an input object used for inputting of coordinates, and enabling automatic designation of a color to be used for drawing. A coordinate detection unit detects coordinates of an input object. Next, display light on the display plane in the vicinity of the coordinates is estimated from display data, and a correction value to remove influences of the display light is calculated. A captured image of an input object used for input operations on the display plane is extracted, and the color of the captured image is corrected with a display light correction value. Thereby, influences of the display light added to the input object are removed, enabling the original color of the input object to be identified.

Abstract: When an index is partitioned and managed in a plurality of indexes in a search system which deals with large amounts of data, the number of documents registered in each partitioned index may be varied, and inefficient data transfer may occur at the time of index reconfiguration when search nodes are added or deleted. In the present invention, mapping information is used to map search node IDs to slot regions obtained by equally partitioning a circular hash value space in which a start point and an end point of the hash value space are assumed to be identical, so that each document is mapped to each partitioned index.

Abstract: A technique is provided in which, in a foreign language document in which a space character is provided for separation of words forming a document, it is possible to reliably detect each word separation and reliably reinsert a space character in the separation. It is decided whether adjacent characters are included in the same word (i.e., presence or absence of space) using: decision by an English writing rule, decision by information as to whether there is a space character in source document data; decision by the identification of character string objects including adjacent characters; and decision by a gap between the character string objects including the adjacent characters. It should be noted that it is preferable to make a decision by these processing in order of this description.

Abstract: In order for a conventional information search system to realize online updating of search indices, there would have to be provided two systems of physical storages for storing copies of indices, namely one for searching and another for updating. By means of a snapshot function provided by an OS, duplicates of original indices are created. A search engine is attached to those duplicates and is used as such, while an index update process is applied to the original index data.

The coordinate input device provided comprises: processing means that detects a size of the input object blocking detection light that travels along the operation detection plane; processing means that generates a down event of the input object when, after blockage of the detection light is initially detected, it is detected that the size has become greater than a first threshold; and processing means that generates an up event of the input object when, following detection of a maximum value of the size, it is detected that the size has become smaller than a second threshold.

Abstract: With respect to a coordinate designation device capable of detecting simultaneous operational input for a plurality of coordinates, occurrences of erroneous operations during textual input, etc., are suppressed. An elapsed time from a previous up operation up to a new down operation is calculated, and, if the calculated elapsed time is equal to or less than a threshold, an event for the input information is issued at the detected coordinates of the down operation. In addition, a traveled distance from coordinates at the time of starting input up to the current coordinates is calculated, and, if the calculated traveled distance is equal to or greater than a threshold, an event for the input start point is issued at the coordinates at the time of starting input.
