Abstract: A non-transitory computer-readable storage medium stores a recognition program that causes a computer to execute a process. The process includes recognizing a plurality of characters from handwritten characters in input handwritten data; setting reference positions of a specific handwritten character and an adjacent handwritten character included in the handwritten characters based on recognition results of the recognized characters, the specific handwritten character and the adjacent handwritten character corresponding to a specific character and an adjacent character included in the recognized characters, respectively, the adjacent character being located adjacent to the specific character; determining whether a space is present between the specific character and the adjacent character based on the reference positions; and generating space information indicating a result of the determining.

Abstract: A method of recognizing characters is disclosed, which includes displaying, on a screen on which a handwriting input can be accepted, an image that suggests a first input area and a second input area, the first input area and the second input area being partly overlapped; and recognizing a handwritten input in the first input area and a handwritten input in the second input area as different characters.

Abstract: A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process including detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen, based on character string display information, specifying a stroke of a closed curved line designated on the screen based on input operation information, and specifying one or a plurality of successive characters, in which a ratio of an area of a selected region based on uppermost, lowermost, leftmost, and rightmost points of the stroke of the closed curved line in the character region to an area of the character region exceeds a threshold, as selected character among a respective character of the displayed character string overlapped with the stroke of the closed curved line.

Abstract: A method that includes correcting at least one of a character image of a target replacement character or stroke information of the target replacement character, in response to a designation of a specific character among recognized characters from handwriting input and an input of the target replacement character that is to replace the specific character, and updating at least one of a character image of the recognized characters or a stroke image of the recognized characters by utilizing at least a corrected one of the character image or the stroke information. The at least one of the character image or the stroke information is corrected based on coordinate information corresponding to the specific character. The coordinate information is generated from at least one of the character image of the recognized characters or the stroke image of the recognized characters that are stored in a memory.

Abstract: A non-transitory computer-readable recording medium has stored therein a compression program that causes a computer to execute a process. The process includes: extracting a numeric character string from input data, the numeric character string indicating a numerical value and including therein at least one numeral; and converting the numeric character string to a compressed code utilizing a dictionary that associates numeric character strings and compressed codes.

Abstract: A computer-readable recording medium stores therein an information processing program that causes a computer to execute storing an aggregate of layers of nodes respectively having a pointer to an upper node, pointers to a leaf and/or a lower node and branches to lower nodes; obtaining a totaling result of appearance frequencies of character codes described in a file; classifying the character codes by layer, based on appearance probabilities thereof and the totaling result; calculating, based on a quantity of character codes in an ith layer and for the ith layer, a quantity of pointers pointing to leaves, and based on the quantity calculated and for the ith layer, further calculating a number of times nodes are used and a quantity of pointers pointing to lower nodes; generating, based on calculation results, a Huffman tree; and converting the Huffman tree into a node-less Huffman tree and storing the node-less Huffman tree.
