Information processing apparatus, information processing method and program therefor

An information processing apparatus includes first and second position acquiring units which respectively acquire a position metadata piece from a target data piece and position metadata pieces from plural data pieces different from the target data piece. A target acquiring unit acquires target metadata pieces other than the position metadata pieces from the other data pieces, and an analysis unit analyzes a distribution of the target metadata pieces based on positions indicated by the position metadata pieces acquired from the other data pieces. An assignment unit assigns to the target data piece a target metadata piece that has a value related to the target data piece, the target metadata piece being selected from among the analyzed target metadata pieces, based on the distribution and the position indicated by the position metadata piece acquired from the target data piece.
