Information retrieving system and method

An information retrieving method comprising:

• allowing a user to indicate a plurality of retrieval keys;
• extracting elements of feature vector that correspond to the retrieval keys, respectively;
• comparing averages of distances between corresponding elements of the feature vector, and selecting a prescribed number of elements in a distance average ascending order as retrieval feature vector to be used in retrieval;
• retrieving information stored in an information storing section by using the retrieval feature vector as retrieval executing keys;
• selecting the elements of the feature vector that have not been extracted as the retrieval feature vector as arrangement feature vector among the elements of the feature vector of each retrieval key;
• and
• classifying and arranging results of the retrieval by using the arrangement feature vector as features of the arrangement;
• and
• displaying a result of the arrangement.

A program for performing an information retrieving operation, the program comprising program codes for:

• a retrieval key indicating operation in which a user indicates a plurality of retrieval keys;
• a feature vector extracting operation for extracting elements of feature vector that correspond to the retrieval keys, respectively;
• a retrieval feature vector selecting operation for comparing averages of distances between corresponding elements of the feature vector, and selecting a prescribed number of elements in a distance average ascending order as retrieval feature vector to be used in retrieval;
• a retrieving operation for retrieving information stored in an information storing section by using the retrieval feature vector as retrieval executing keys;
• an arrangement feature vector selecting operation for selecting the elements of the feature vector that have not been extracted as the retrieval feature vector as arrangement feature vector among the elements of the feature vector of each retrieval key;
• an arranging operation for arranging results of the retrieval by using the arrangement feature vector as features of the arrangement;
• and
• a display operation for displaying a result of the arrangement.
