System and method for supporting cluster analysis and apparatus supporting the same

A cluster analysis service apparatus for supporting a cluster analysis, the cluster analysis service apparatus comprising:

• an apparatus storage unit configured to store data;
• an apparatus input unit configured to generate an input signal related to at least one of k values within a predetermined range, a convergence condition, and an iteration frequency that are provided for cluster analysis of the stored data;
• and
• an apparatus control unit configured to control such that a k-means clustering is performed and center values of the k values are calculated based on the k values and the iteration frequency until the convergence condition is satisfied, wherein the k-means clustering is performed whenever data is updated.

A method of supporting a cluster analysis, the method comprising:

• by a cluster analysis service apparatus, performing an initialization on center value vectors based on k values within a predetermined range and an iteration frequency that are input;
• transmitting data and the initialized center value vectors in a distributed manner to data nodes of a distributed processing service apparatus;
• by the data nodes, performing a k-means clustering based on the data and the initialized center value vectors that are transmitted in a distributed manner;
• by the data nodes, providing results of the analysis to the cluster analysis service apparatus;
• by the cluster analysis service apparatus, selecting an optimum result of the results of the analysis and sharing the selected result with the data nodes;
• by the data nodes, assigning clustered indexes obtained by applying the selected result to data;
• by the cluster analysis service apparatus, performing an index calculation on the data to which the clustered indexes are assigned;
• and
• updating a previously stored k value using a value having an optimum result of the index calculation.
