Document Attribute Detection Using Date String Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing documents with expiration dates, such as contracts and inspection certificates, often fail to accurately identify and track these dates, leading to potential expiration issues due to lack of clear indication within the document.
Innovation Solution
An information processing apparatus comprising a reading unit and a determining unit that reads documents, specifies character strings representing dates and periods, and determines document attributes, such as expiration dates, through character recognition and database referencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing systems are used to manage documents with expiration dates, then document storage and basic tracking are possible, but accurate identification and tracking of expiration dates cannot be achieved when dates are not clearly indicated
Solution Approach 1:
The patent introduces an intermediary system consisting of an expiration date detector and attribute determination unit that acts as a mediator between the document and the management system. This intermediary automatically extracts and analyzes expiration date information, even when not clearly indicated, by using pattern recognition and database referencing to bridge the gap between ambiguous document content and precise expiration date identification.
Solution Approach 2:
The patent replaces manual inspection and mechanical search methods with automated information processing systems. The expiration date detector uses character recognition and pattern matching algorithms to automatically identify expiration dates, while the attribute determination unit uses database lookups and logical reasoning to determine document attributes, substituting human effort with automated computational processes.
2Productivity
If manual document management is used, then flexibility in handling various document formats is possible, but automation and efficiency are reduced
Solution Approach 1:
The patent implements a self-service system where the document management apparatus automatically performs expiration date detection, attribute determination, and management without requiring manual intervention. The system reads documents, automatically detects expiration dates, determines attributes by referencing databases, and manages documents based on detected information, enabling the system to serve itself and eliminating the need for human operators.
Solution Approach 2:
The patent creates a universal document management system that can handle various document types and formats through a single integrated apparatus. The expiration date detector and attribute determination unit are designed to work with multiple document formats and styles, making the system versatile and adaptable to different document kinds while maintaining high automation levels.
3Reliability
If simple storage methods are used, then storage cost is reduced, but accurate tracking and management of document attributes cannot be achieved
Solution Approach 1:
The patent applies preliminary action by pre-establishing a database of document attributes and expiration date patterns before the actual document management process. The system prepares reference data and detection rules in advance, allowing it to quickly and accurately determine document attributes when expiration dates are detected, thereby ensuring reliable management without requiring complex real-time processing.
Data Source
AI summary
An information processing apparatus includes a reading unit and a determining unit. The reading unit reads a document. The determining unit specifies, based on a result of reading of the document, a first character string representing a date and a second character string representing a period, and determines an attribute of the document in accordance with the first character string and the second character string.
