Abstract: When a search device receives a query from a terminal device, the search device specifies portions of OR condition containing OR operators from the query. The search device judges whether reverse axes and OR operators are contained in the specified portions of OR condition. When reverse axes and OR operators are contained, the search device divides the query into subqueries using the OR operators contained in the portions of OR condition as division points.

Abstract: An information location management method which is capable of updating information location information corresponding to locations of information which a user desired to acquire, as required. A communication log storage section stores a communication log of emails exchanged with an external device over an external network. An acquisition destination-selecting section reads out the communication log and identifies an other-end party with whom a target user has performed transmission and reception of emails not less than a predetermined number of times to select the other-end party as an information acquisition destination. An information location-generating section extracts key information related to a location of information at the information acquisition destination contained in the emails transmitted and received to and from the information acquisition destination, to generate information location information. The information location information is stored in an information location-accumulating section.

Abstract: A search method for causing a computer to execute the search method of searching for and retrieving, when a search formula to document data having a hierarchy structure whose elements are delimited by an element identifier is obtained, data corresponding to the search formula from the document data, stores, when the search formula is obtained, the search formula to a memory device; determines, when the data corresponding to the search formula is searched for and retrieved from the document data, whether or not a hierarchy management is necessary to the search formula based on the search formula; and searches for and retrieves, when the hierarchy management is not necessary to the search formula, the document data corresponding to the search formula without executing the hierarchy management.

Abstract: A collation processing device has a document storage unit, axis transforming unit, automaton creating unit, and collating processing unit. The document storage unit stores document data having a hierarchical structure in which elements are sectioned by element identifiers. The axis transforming unit executes axis transformation on a search formula when the search formula is obtained, whereby the search formula concerned is transformed to a search formula constructed of child axes. The automaton creating unit identifies the type of element identifiers contained in the transformed search formula to create the automaton corresponding to the search formula concerned. The collating processing unit collates data contained in the document data with the automaton to output the data corresponding to the search formula.

Abstract: A method of manufacturing a hot-formed steel product is provided, by which when a steel sheet is subjected to hot forming, excellent forming can be achieved without causing break or a crack during forming. When a steel sheet is subjected to hot forming to obtain a hot-formed product, the steel sheet is heated to be austenitized, then the steel sheet is cooled to a temperature range of martensite transformation start temperature Ms or less at an average cooling rate of 20° C./sec or more, and then the steel sheet obtained in this way is heated to Ac1 transformation temperature or more, then subjected to hot forming, thereby an excellent hot-formed product is obtained.

Abstract: A database system includes a query controller and an XML database, and is connected to other terminal devices such as a user device via a network. In such a configuration, when a query request is transmitted from the user device to the XML database, the query controller determines whether an access to a node corresponding to the query request by a user specified by user information is permitted or denied by referring to access information relative to each node stored in an access control DB, to extract an access-permitted query request, and transfers only the extracted query request to the XML database.

Abstract: A data sorting program that is capable of performing a data sorting process by using a small capacity of memory at a fast speed. A computer executing the data sorting program has the following functions. A concise ordered TRIE creator creates a root, sequentially reads the characters of each data, and when a prescribed number of data passed a certain node connected to the root before and a child node corresponding to a character next to a character associated with the certain node has not been created, creates the child node so that the child nodes of the certain node have a prescribed arrangement. A partition determination unit sets partitions between prescribed nodes. A data grouping unit groups the data into a plurality of data groups according to the partitions.

Abstract: A computer-readable storage medium storing a dataset sorting program is provided to sort records in a dataset into a plurality of destination groups according to a given key item specification. An item value extractor creates an item value list for every record. Then a frequent tree builder builds a frequent tree from the item value lists by finding patterns of item values that appear more often than a threshold specified by a given growth rate parameter. Each item value pattern is a leading part of an item value list with a variable length. A destination group mapper associates each node of the frequent tree with one of the plurality of destination groups. A record sorter traces the frequent tree according to the item value list of each given record, and upon reaching a particular node, puts the record into the destination group associated with that node.
