Mail Server Keyword Extraction Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively manage and track the extraction status of inappropriate emails, leading to compliance violations and inability to identify users engaging in harmful behavior, such as power harassment, as updating extraction conditions does not provide clear insights into violators.
Innovation Solution
A mail server system that analyzes and classifies emails using a database of keywords, categorizes transmission status, and periodically updates keyword lists to adapt to changing patterns, enabling accurate identification and prevention of inappropriate content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If keyword extraction conditions are updated to adapt to changing patterns, then adaptability improves, but measurement precision of extraction status deteriorates
Solution Approach 1:
The patent segments the keyword extraction system into multiple independent components: a keyword management table storing extraction conditions, an extraction status management table tracking individual keyword extraction histories, and a mail address management table. This segmentation allows each component to be updated independently, enabling adaptability improvements without compromising the precision of extraction status tracking for previously processed emails.
Solution Approach 2:
The system performs preliminary actions by maintaining a comprehensive extraction status management table that records the extraction status of each keyword for every mail address before keyword extraction conditions are updated. When conditions change, the system can reference this pre-recorded status information, ensuring that historical extraction precision is preserved while adapting to new patterns.
2Reliability
If comprehensive email monitoring is implemented to identify violators, then reliability improves, but device complexity increases
Solution Approach 1:
The patent implements a universal mail address management table that serves multiple functions: storing mail address information, tracking extraction status across different keywords, and identifying violators. This single data structure performs what would otherwise require multiple separate systems, improving compliance monitoring effectiveness while avoiding the complexity of multiple independent tracking mechanisms.
Solution Approach 2:
The system establishes feedback loops where extraction results are continuously recorded in the extraction status management table, which then feeds back into the keyword management process. This automated feedback mechanism enables comprehensive monitoring and violator identification without requiring complex manual intervention systems, as the data automatically circulates through the management tables.
Data Source
AI summary
A mail server displays a list of mail addresses of the sources of mails matching with an extraction condition for inappropriate mails, the list being classified into levels which are divided according to the transmission status of mails matching with the extraction condition for each mail address. Then, in response to the selection of one of the mail addresses from the displayed list, the mail server displays the transition of the transmission status of the mails which match with the extraction condition and have the selected mail address.
