Title:
UNSTRUCTURED DATA ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/001571
Kind Code:
A1
Abstract:
[Problem] When a data management system stores a large volume of unstructured data and an application specifies a short response time, there is insufficient time to extract and process information from the stored unstructured data, and sending back an on-time response is impossible. Also, even if an application makes a demand with a high level of secrecy, a data management system will request data analysis from an external network, and information leakage will occur. [Solution] When an application demands data from a data management system, a response time, information secrecy level and response precision level are specified. A data management system provides a means for requesting data analysis from an external network only when the secrecy level is low. Information extracted from unstructured data is managed by appending a precision-based score thereto, and is mapped to a precision level. When the response time is short, only locations with large scores are searched from managed information.
