Email Attachment Detection via Keyword Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget to attach files to emails, leading to unnecessary re-sending of messages and wasting time and bandwidth, as existing systems lack effective detection mechanisms to identify the need for attachments.
Innovation Solution
A system that analyzes the subject line and message body for predetermined keywords, phrases, and statistical significance to suggest the addition of attachments, allowing users to add or edit messages before sending, with a database that updates based on user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the user sends the email immediately without checking attachments, then the sending speed is improved, but the reliability of complete information transmission deteriorates
Solution Approach 1:
The system performs preliminary analysis of the email content and subject line to detect potential attachment needs before the user sends the email. By examining keywords in the subject line and body text, the system proactively identifies messages that should likely have attachments, allowing users to add them before sending rather than discovering the omission after transmission.
Solution Approach 2:
The system provides feedback to the user by displaying a notification when it detects that an attachment may be missing. This feedback mechanism allows users to review the suggestion and either add the attachment or confirm that none is needed, thereby maintaining both fast sending capability and reliable information completeness.
2Reliability
If the user resends the email with the attachment after noticing the omission, then the reliability of information transmission is improved, but the loss of time increases
Solution Approach 1:
The attachment detection and notification system operates before the user sends the email, performing the reliability check in advance. This prevents the need for subsequent resending operations, thereby eliminating the time loss that would result from discovering the missing attachment after transmission.
3Reliability
If the user resends the email with the attachment after recipient notification, then the reliability of information transmission is improved, but the loss of bandwidth increases
Solution Approach 1:
The system performs preliminary detection and notifies the user before the email is sent, preventing the transmission of incomplete messages in the first place. This avoids the wasteful retransmission of emails that would consume additional bandwidth, as the attachment issue is resolved before initial sending occurs.
4Measurement precision
If the system analyzes the message body for attachment indicators, then the detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The system extracts and analyzes only specific relevant elements from the email, such as keywords in the subject line and predetermined phrases in the body text. By focusing on these extracted indicators rather than analyzing the entire message comprehensively, the system achieves good detection accuracy while keeping the analysis complexity manageable.
Solution Approach 2:
The system applies different analysis strategies to different parts of the email. For example, it performs keyword matching on the subject line and template matching on the body text, using appropriate detection methods for each section. This localized approach improves overall detection accuracy without requiring uniformly complex analysis across the entire message.
Data Source
AI summary
A user is writing an email or other message. The message is inspected for a predetermined word and for at least one of: a predetermined phrase or a template match. A score is generated if the predetermined phrase or the template match is detected. A suggestion is provided to a user that the message may need an attachment if the predetermined word is detected or if the score is greater than a predetermined score. The inspection may begin when the user begins creating the message, indicates that the message should be sent, or at some point in between. The user may provide feedback that the suggestion is accepted or that the suggestion is rejected.
