  • Patent number: 8849726
    Abstract: An information processing apparatus that encodes input structured data according to an encoding rule is provided. When the structured data matches a specified learning target, this apparatus determines the start of learning of the encoding rule. Upon determining the start of learning, the apparatus recognizes the structure and data type of the structured data and starts learning the encoding rule. The apparatus stores the structured data until an end condition corresponding to the specified learning target holds and the end of learning of the encoding rule is determined. Upon determining the end of learning, the apparatus encodes the stored structured data according to the learned encoding rule.

  • Patent number: 8185565
    Abstract: An information processing apparatus for combining a plurality of structured documents, including an acquiring unit, for each of the plurality of structured documents, correspondence information showing a correspondence between vocabulary information and token information, and encoded information in which the vocabulary information included in the structured document has been replaced with corresponding token information, a replacing unit for, if the vocabulary information included in a first correspondence information is common with the vocabulary information included in a second correspondence information, replace the common vocabulary information with a reference to the common vocabulary information included in the second correspondence information, and a combining unit to generate combined information by combining the correspondence information and the encoded information, of each of the plurality of structured documents.

  • Patent number: 8156088
    Abstract: Digit counts c? after the decimal point of attribute values in a structured document are acquired (S404). The detected attribute values are transformed into value character strings that represent integer values by manipulating the decimal point positions of the attribute values in accordance with a maximum digit count of the acquired digit counts (S406). The transformed value character strings and the maximum digit count C are encoded (S407).

  • Patent number: 8117217
    Abstract: There is provided an information processing apparatus for providing encoding technology that enables data size reductions and analysis processing speed improvements even for data including elements having complex attribute values. The apparatus includes a file input unit that inputs a file including elements having a data stream of a predetermined format as an attribute value, a hierarchy information setting unit that sets hierarchy information indicating hierarchical positions for each of one or more delimiters included in the data stream, a structure information generating unit that generates structure information that defines mutual relations between hierarchy information, a designating unit that designates a region of a data stream of a predetermined format from the input file, and an encoding unit that detects delimiters from the designated region and, based on detected delimiters and structure information, encodes a data stream of the designated region based on a preset structured description language.

  • Patent number: 7970802
    Abstract: XML document data is divided in a page tag unit, and an encoding table is created for each of the XML divided document data. Then, by using the encoding table, the XML divided document data is encoded to create code division data, and then the encoding table and code division data corresponding to the encoding table are sent to a printer. In this manner, the encoding tables with small redundancy and small data size are created, and the encoded XML document data and the code division data in small pieces are sent to the printer. Thus, even an apparatus with a small usable storage area such as an inexpensive printer can decode the XML document data by using the encoding tables with the small data size.

  • Patent number: 7793207
    Abstract: An information processing apparatus and method for analyzing structured document data and outputting the analytical results in units of structure. The apparatus detects a specific character string indicating a first data form contained in the structured document data. When the specific character string is detected, data corresponding to this specific character string is converted to a second data form that is different from the first data form and the data of the second data form is stored.
