Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a data processing device capable of extracting data including a meta-character representation meaning that one is selected from among a plurality of numeric values.SOLUTION: Pieces of data including meta-character representations each of which means that one numeric value is selected from among a plurality of numeric values are stored in a database 70. An extraction unit 30 includes: a unit character division unit 21 which takes each of numeric values and characters other than the numeric values as one unit character and takes each of the meta-character representations as one unit character to divide each of the pieces of data into unit characters and calculates the number of divided unit characters as the number of unit characters; a number-of-unit-characters based extraction unit 32 which extracts, as candidate pieces of data, pieces of data of which the numbers of unit characters are within a prescribed range; a distance calculation unit 33 which calculates distances between object data and the pieces of data stored in the database; a distance-based extraction unit 34 which extracts, as candidate data, pieces of data from which the calculated distances to the object data are a prescribed value or smaller, out of the candidate pieces of data extracted by the number-of-unit-characters based extraction unit 32.
【課題】複数の数値の中からひとつが選択されることを意味するメタ文字表現を含んだデータを抽出することができるデータ処理装置を提供する。【解決手段】データベース70には、複数の数値の中からひとつの数値が選択されることを意味するメタ文字表現を含んだデータが格納されており、抽出部30は、対象データに含まれる、ひとつの数値および該数値以外の文字を一単位文字とするとともに、メタ文字表現を一単位文字として単位文字ごとに分割し、分割された単位文字の数を単位文字数として算出する単位文字分割部21と、単位文字数が所定範囲に該当するデータを、候補データとして抽出する単位文字数別抽出部32と、対象データとデータベースに格納されたデータとの間の距離を算出する距離算出部33と、単位文字数別抽出部で抽出された候補データのうち、算出された距離が所定値以下のデータを、候補データとして抽出する距離別抽出部34と、を有する。【選択図】図1 |
