Statistical analysis system and statistical analysis method using conversational interface

A statistical analysis system using a conversational interface, the system comprising:

• a conversational interface means (10) for providing inquiry information to a user to extract a user's purpose of a statistical analysis and variable information, and for collecting answer information provided from the user to inquiries;
• an analysis feature information extraction means (20) for extracting analysis feature information by using the answer information of the user acquired by the conversational interface means (10);
• an algorithm management means (30) for storing and managing statistical algorithms therein and for providing the statistical algorithms according to a request from a statistical analysis control means (40);
• the statistical analysis control means (40) for controlling execution of the statistical analysis in such a manner that the conversational interface is provided to the user through the conversational interface means (10), the analysis feature information is extracted through the analysis feature information extraction means (20) from the answer information collected through the conversational interface, and the statistical algorithm to be used in the statistical analysis is selected according to the analysis feature information;
• and
• a statistical analysis means (50) for performing the statistical analysis according to the statistical algorithm set by the statistical analysis control means (40) and for providing information about a result thereof.
