PROBLEM TO BE SOLVED: To provide a selecting device, a selecting method, a program and a recording medium which solve the problem that it is difficult to appropriately select only desired data when there is a large amount of electronized data even though various data are electronized and used in accordance with the advancement and popularization of computers and can efficiently obtain a set related strongly to a predetermined reference element among a plurality of elements stored in a database or the like.
SOLUTION: This selecting device 10 for selecting an adjacent element set whose strength of a relation to the predetermined reference element satisfies a predetermined condition among the plurality of elements is provided with an adjacent element set candidate selecting part 110 for selecting a set of elements whose relation to the reference element is determined to be stronger among the plurality of elements as each of a plurality of adjacent element set candidates being a plurality of candidates in which the adjacent element sets are different from one another, and an adjacent element set selecting part 130 for selecting a set of elements whose relational strength to the reference element satisfies the predetermined condition as an adjacent element set in a sum of sets of the plurality of adjacent element set candidates.
