Data monitoring means adds tag information representing a document conversion method to hyperlink information included in a hypertext type document sent to a user-side device from a server-side application, and sends to the user-side application the hyperlink information to which the tag information is added. When the tag information representing the document conversion method is included in a command to request retrieval which is sent from the user-side application, the data monitoring means converts the document sent from the server-side application as the results of the retrieval in accordance with the document conversion method represented by the tag information and sends the converted document to the user-side application.

To a multimedia information file including three-dimensional image data, three-dimensional display control information is added that indicates an intended three-dimensional display method for the three-dimensional image data or a data format in which the data is recorded. A three-dimensional image reproduction apparatus performs conversion appropriate for data characteristics derived from the three-dimensional display control information and then provides display. Recorded three-dimensional image data is thus given versatility so that the same three-dimensional image data can be used commonly to different three-dimensional display schemes.

Judgement is made to determine whether or not an access request from a host computer is a write request and whether or not the contents of the write request are log information indicating contents of database processing executed in a buffer by the host computer. When the contents of the write request are the log information, position information indicated in the log information is converted into physical position information in a primary storage system using a conversion table indicating a correspondence between logical position information recognized by the host computer and physical position information in the primary storage system. According to the contents of the log information, data is updated in a database area of the primary storage system represented by the physical position information converted using the conversion table. The access request is sent to a secondary storage system.

In one aspect, the invention divides an audio signal into auditory events, each of which tends to be perceived as separate and distinct, by calculating the spectral content of successive time blocks of the audio signal (5-1), calculating the difference in spectral content between successive time blocks of the audio signal (5-2), and identifying an auditory event boundary as the boundary between successive time blocks when the difference in the spectral content between such successive time blocks exceeds a threshold (5-3). In another aspect, the invention generates a reduced-information representation of an audio signal by dividing an audio signal into auditory events, each of which tends to be perceived as separate and distinct, and formatting and storing information relating to the auditory events (5-4). Optionally, the invention may also assign a characteristic to one or more of the auditory events (5-5).

A server unit (400) recognizes a travel route search request together with a current position information and a destination information from a terminal unit (300) over a network (200) and searches for a travel route with use of a matching data of a map information. The server unit (400) sends a matching mesh information including a node and link that represent a road corresponding to the travel route and a display mesh information for areas other than the areas represented by the matching mesh information together with the information for the travel route to the terminal unit (300) over the network (200). The terminal unit (300) displays a road based on the matching mesh information and the information excluding the road based on the display mesh information on a terminal display. Thus, the information amount of the map information to be processed can be reduced thereby improving the processing efficiency.

A method of mapping data items to sparse distributed representations (SDRs) includes clustering in a two-dimensional metric space, by a reference map generator, a set of data documents selected according to at least one criterion, generating a semantic map. The semantic map associates a coordinate pair with each of the set of data documents. A parser generates an enumeration of data items occurring in the set of data documents. A representation generator determines, for each data item in the enumeration, occurrence information. The representation generator generates a distributed representation using the occurrence information. A sparsifying module receives an identification of a maximum level of sparsity. The sparsifying module reduces a total number of set bits within the distributed representation based on the maximum level of sparsity to generate an SDR having a normative fillgrade.
