65 results about "String Value" patented technology

Compilers use string literals to create string values that are stored in string variables. When code containing a string literal is compiled, the compiler turns the literal into a string value. In the example below the string literals are converted to string value and assigned to their respective variables.

Compression processing method and device of character string type column

ActiveCN104408192ASolve the problem of low compression processing efficiencyImprove compression processing efficiencySpecial data processing applicationsAlgorithmTheoretical computer science
The invention discloses a compression processing method and a compression processing device of a character string type column. The compression processing method of the character string type column includes: confirming a data list to be compressed; confirming a character string column in the data list to be compressed, wherein using the character string column as the character string type column in the data list to be compressed; confirming key value corresponding to character string value in the character string column, wherein using the key value as value of data types; replacing the character string value in the character string column with the key value corresponding to the character string value in the character string column; obtaining a first storage index, wherein using the first storage index as a corresponding index built according to the key value corresponding to the character string value in the character string column; compressing the data list to be compressed according to the first storage index. The compression processing method and the compression processing device of the character string type column solve the problem that compression processing of the character string type column is low in efficiency in the prior art.

Graph similarity calculation system, method, and program

The similarity between graphs having an extremely large number of nodes, such as an SNS, a link of WWW, etc., can be obtained within a reasonable time. A unique value is provided to a label of a node in a graph. Preferably, the value is a fixed-length bit string. In this case, the length of the bit string is selected to be sufficiently larger than the number of digits by which types of labels can be expressed. With respect to one graph, nodes of the graph are sequentially visited by an existing graph search method, such as a depth-first search, a breadth-first search, and the like. At this time, in the system, when one specific node is visited, a calculation is performed for bit string label values of all nodes adjacent to the specific node and the bit string label value of the specific node, to obtain a bit string value. The hash calculation is performed for the calculated bit string value and the original bit string label value of the node to obtain another bit string label value, and this value becomes the label value of the node. After finishing the visit to all nodes in one graph, the label values of all nodes are rewritten. When the same treatment is performed for another graph which becomes a target of the graph similarity comparison, label values of all nodes in this graph are rewritten. Therefore, with respect to one graph, a ratio of label values which are identical to the label values in another graph, per all nodes is calculated to obtain the similarity.

Character string value domain segmenting method and device

ActiveCN106294371AAvoid problemsGuaranteed to be completely undistortedProgram controlMulti-dimensional databasesData warehouseAlgorithm
The invention discloses a character string value domain segmenting method and a character string value domain segmenting device which are applied to the field of data warehouse integration. The method comprises the following steps: extracting character strings with the maximal ASCII (American Standard Code for Information Interchange) code value and the minimal ASCII code value in a data primary key to be extracted; converting the character strings into big integers by weight expansion sum according to the ASCII code values and a preset scale cardinal number to form a range to be segmented; solving a range difference; performing equal segmenting on the range to be segmented according to the range difference and a preset segmenting number to obtain a segmenting step length so as to obtain big integers corresponding to segmenting nodes; reducing the big integers corresponding to the segmenting nodes into segmenting node character strings by adopting an Euclidean algorithm; generating a plurality of data extracting statements according to the segmenting node character strings to realize multithreaded accelerated extracting. The method is also optimized, namely, a reduced scale cardinal number is adopted in the processes of the weight expansion sum and the Euclidean algorithm. According to the method and the device, the concurrency and the high efficiency in a data transmission process are greatly improved.
