A non-transitory computer-readable recording medium stores an encoding program that causes a computer to execute a process. The process includes first encoding a first character string in input data to a first code, when the first character string being registered in a first dictionary, the first code being associated with the first character string in the first dictionary; second encoding a second character string in input data to a second code and registering the second character string to a dynamic dictionary, when the second character string being not registered in the first dictionary, the second code being associated with the second character string and preliminary information in the dynamic dictionary; and generating encoded data including the encoded input data and the dynamic dictionary.

Encoding method and information processing device

A computer-readable recording medium stores therein an information searching program that causes a computer having access to archives including a compressed file group of compressed files that are to be searched and that have described therein character strings, to execute: sorting the compressed files in descending order of access frequency of the compressed files; combining the compressed files in descending order of access frequency after the sorting at the sorting such that a storage capacity of a cache area for a storage area that stores therein the compressed file group is not exceeded by a combined size of the compressed files combined; and writing, from the storage area into the cache area, the compressed files combined at the combining, the compressed files combined being written prior to a search of the compressed files combined.

Information searching apparatus, information managing apparatus, information searching method, information managing method, and computer product

A recording medium stores an information processing program that causes a computer to execute storing a compression symbol map group having a bit string indicating for each character code, presence or absence of the character code in a file group, and a Huffman tree whose leaf corresponding to the character code has a pointer to a compression symbol map of the character code, the Huffman tree converting the character code into a compression symbol of the character code; compressing sequentially and according to the Huffman tree, a character code to be compressed and described in a file of the file group; detecting access to the leaf at the compressing; identifying by a pointer in the accessed leaf, a compression symbol map of the character code to be compressed; and updating a bit that indicates presence or absence of the character code to be compressed, in the identified compression symbol map.

Computer product, information processing apparatus, and information search apparatus

A computer-readable, non-transitory medium stores a program that manages compressed file groups on a plurality of slave servers. The file groups include compressed files that are to be searched and have character strings. Each of the compressed file groups is expanded, using a Huffman tree that was used for compressing the compressed file group. A common compression parameter is generated based on appearance frequency, by summing, for each character, the appearance frequency in each of the compressed file groups. The expanded files are recompressed using the common Huffman tree such that sums of the access frequencies of the compressed files that are origins of the recompressed files are substantially equivalent among various slave servers. New archives including the re-compressed files are transmitted to the respective slave servers.

Apparatus for searching and managing compressed files

Corresponding to each notification system of position information different for each carrier and terminal, the position information about a user of an information terminal can be obtained, and a service can be provided according to position information without a service provider managing user position information. An information terminal user position information acquisition apparatus includes a terminal determination unit for determining the type of an information terminal depending on data transmitted from an information terminal of a user, and a position information extraction means for extracting the position information about the user from the data transmitted from the information terminal.

Position information acquisition apparatus and method

The present invention has as its object to provide text information to a listener with voice when music is reproduced from a medium on which the text information is stored together with music data and to provide easily and smoothly use of the text information. The present invention is a text information read-out device for reading out text information from a medium on which text information is stored together with music data, including a text information extraction unit for extracting text information, a voice synthesizer obtaining voice data from the extracted text information, and a controller for controlling a read-out timing of the voice data in synchronism with reproduction of music data.
