Claim One:
1. A system for estimating a location label of a vector dataset without any location label from a plurality of vector datasets respectively with location labels using a computer, the system comprising: storage means provided in the computer; means for storing the vector datasets in the storage means of the computer; means for calculating the similarity between the vector dataset without any location label and each neighboring vector dataset with a location label, by using any one of a q-norm wherein 0<q<1 and an exponential attenuation function; and means for estimating the location label of the vector data without any location label from the calculated similarities, wherein the similarities are calculated by means of the following expression using the q-norm, 
 W X (i,j) =exp(−∥ X (i) −X (j) ∥ q q ), where X (i) and X (j) denote i-th and j-th vectors, respectively, and  X  q = ( ∑ d = 1 n ⁢  X d  q σ d ) 1 q where n denotes the number of dimensions of the vector and 0<σ d <∞.
