  • Patent number: 10521414
    Abstract: An encoding device 100 encodes a target file by using a static dictionary 121 and a dynamic dictionary 122. The encoding device 100 generates index information of the target file by folding a file axis and a word axis of the target file utilizing base numbers, respectively, the index information indicates presence information of words registered in the static dictionary 121 and the dynamic dictionary 122. The encoding device 100 generates, when the target file is updated, the difference information indicating difference of the index information with respect to the file axis direction or the word axis direction.

  • Patent number: 9916314
    Abstract: An AND operation is performed for an integrated appearance map of a compression code of character data “”, an integrated appearance map of a compression code of character data “”, and an integrated deletion map for a segment. The AND result is “1100” and it is found that the character data “” and “” are likely to be present in the segments (sg1(1)) and (sg1(2)). Since the segments are specified from the AND result, the AND operations are performed. As a result, the segments are specified and the AND operations are performed. As a result, a file number 3 is specified from the segment (sg0(1)) and a file number 19 is specified from the segment (sg0(5)). Therefore, it is found that both of the character data “” and “” are present in compression files (f3) and (f19).

  • Patent number: 9628110
    Abstract: The encoding apparatus registers, in a dynamic dictionary, strings in input text data that are not contained in a static dictionary. The encoding apparatus adds, to first hashed data obtained by individually N-dimensionally hashing words contained as registered items in the static dictionary, hashed data obtained by individually hashing strings registered in the dynamic dictionary. The encoding apparatus 100 determines, by using the first hashed data, whether each input string has been registered in the static dictionary 124 and whether the string has been registered in the dynamic dictionary 122. In accordance with the result of the determination, the encoding apparatus 100 performs encoding based on a content registered in the static dictionary or the dynamic dictionary.
