Abstract: A data processing device (10) includes a vector generation unit (1411, 1421) configured to obtain a number of appearance or a frequency of appearance of a word used in a caption of a row of a cell and in a caption of a column of the cell at which the row and the column of table data intersect with each other and generate a vector which has the obtained number of appearance or the obtained frequency of appearance as a value of an element.

Abstract: A synonym extraction apparatus determines, for compound words included in the document, that types of nouns constituting the compound word are each a Sahen-noun or another noun type to determine a pattern of a sequence of the types of the nouns constituting the compound word, extracts a group of compound words having an identical pattern of the sequence of the types, extracts compound words having an identical leading or ending word from among them, and creates, for a group of compound words having the identical pattern of the sequence of the nouns and the identical leading or ending word, a co-occurrence vector having, as a component, a noun appearing in the same sentence as the corresponding compound word, and outputs, as synonyms, a group of compound words having a degree of similarity between the co-occurrence vectors of the compound words equal to or greater than a predetermined threshold.

Abstract: A data processing apparatus includes a word selection unit configured to select words corresponding to a part-of-speech type targeted for selection from words disassembled from document data, and a generation unit configured to find, for each of the words selected by the word selection unit, a value obtained by weighting the number of occurrences of each of the words or frequency of occurrences of each of the words according to the part-of-speech type of each of the words to generate a vector with a plurality of the values that are found as values of elements.

Abstract: A synonym extraction apparatus determines, for compound words included in the document, that types of nouns constituting the compound word are each a Sahen-noun or a noun other than a Sahen-noun to determine a pattern of a sequence of the types of the nouns constituting the compound word. The synonym extraction apparatus then extracts a group of compound words having an identical pattern of the sequence of the types of the nouns described above from the document, and then extracts compound words having an identical leading or ending word from among them.

Abstract: A data processing apparatus (10) includes a word selection unit (143) configured to select words corresponding to a part-of-speech type targeted for selection from words disassembled from document data, and a generation unit (144) configured to find, for each of the words selected by the word selection unit (143), a value obtained by weighting the number of occurrences of each of the words or frequency of occurrences of each of the words according to the part-of-speech type of each of the words to generate a vector with a plurality of the values that are found as values of elements.
