Forum Obsolescence Detection via Keyword Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online forums lack an efficient method to identify and update obsolete discussion threads, which can provide outdated advice due to changes in topics such as new regulations or software releases, leading to user reliance on potentially incorrect information.
Innovation Solution
A method and system that extract keywords from discussion threads, assign keyword scores, and reduce scores based on matching keywords from recorded change events, aggregating these scores to flag threads as outdated and display warnings when scores fall below a threshold, ensuring forums remain current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discussion threads are archived indefinitely in forums, then historical information is preserved, but outdated and potentially harmful information continues to be accessible to users
Solution Approach 1:
The system proactively identifies obsolete discussion threads before they cause harm by monitoring for changes in laws, regulations, and standards. When such changes are detected, the system automatically updates the obsolescence status of affected threads, preventing users from accessing outdated information while preserving the threads for historical record.
Solution Approach 2:
The system establishes a feedback mechanism where changes in external environments (laws, regulations, standards) are continuously monitored and fed back to the forum system. This feedback loop enables automatic identification and marking of obsolete threads, ensuring information reliability without permanent removal.
2Reliability
If manual review of discussion threads is performed to identify obsolete content, then information accuracy can be maintained, but significant human resources and time are required
Solution Approach 1:
The system enables automatic selfidentification of obsolete discussion threads by comparing thread content against monitored changes in laws, regulations, and standards. This self-service mechanism eliminates the need for manual review while maintaining high information accuracy, as threads automatically flag themselves when they become obsolete.
Solution Approach 2:
The system replaces manual human review (mechanical process) with automated computer-based monitoring and comparison algorithms. The system automatically detects changes in external environments, compares them against discussion thread content, and identifies obsolete threads, thereby eliminating time-consuming manual moderation while maintaining reliability.
3Reliability
If obsolete discussion threads are removed from forums, then information reliability is improved, but loss of historical discussion data occurs
Solution Approach 1:
Instead of removing obsolete threads, the system applies preliminary action by marking them with obsolescence indicators before they can cause harm. This approach preserves the historical discussion data while clearly signaling to users that the information is outdated, thus maintaining both reliability and historical record.
Solution Approach 2:
The system introduces an intermediary mechanism (obsolescence marking system) between the obsolete thread content and users. Rather than direct removal or unrestricted access, the marking system acts as a mediator that preserves historical data while preventing misinformation propagation through clear visual indicators.

AI summary
The invention relates to a method for identifying obsolete discussion threads. The method includes extracting keywords from a discussion thread and assigning a keyword score to each keyword. The method further includes identifying a change event that is a change affecting a topic of the forum, extracting a keyword from a recorded medium recording the change event, comparing the keyword from the recorded medium with the keywords from the discussion thread to identify a matching keyword, and reducing the keyword score of the matching keyword to a reduced score based on the matching keyword matching the keyword from the recorded medium. The method further includes aggregating the keyword score assigned to each keyword to obtain a total score for the discussion thread, and displaying a warning on a user interface that includes the discussion thread when the total score is below a pre-specified threshold.
