Solution Overview

Problem

The issue of 'topic drift' occurs when the landing page of posted content changes over time, leading to a mismatch between the posted content and its hyperlinked landing page, resulting in user disappointment and potential exposure to malicious content.

Innovation Solution

A system and method for determining topic cohesion between a content item and its hyperlinked landing page by generating content and landing page signals, analyzing these signals to calculate a topic cohesion score, and taking remedial actions if the score falls below a threshold, while promoting content items with high cohesion scores.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the landing page is updated over time to provide new content, then the landing page remains dynamic and useful, but topic drift occurs causing mismatch between posted content and landing page

Engineering Contradiction:
Improvelanding page update capabilityVSAvoidtopic cohesion
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by generating content signals from the posted content and landing page signals from the landing page before comparing them. This proactive approach allows the system to detect topic drift before it significantly impacts user experience, enabling preventive remedial actions to maintain topic cohesion while allowing landing pages to remain dynamic.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop by continuously monitoring topic cohesion between posted content and landing pages. When topic drift is detected through signal comparison, the system triggers remedial actions such as updating hyperlinks or notifying users. This feedback mechanism ensures reliability is maintained while allowing adaptability, as the landing page can be updated knowing the system will detect and respond to any topic drift.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If users are allowed to freely hyperlink content to any landing page, then ease of operation is improved, but exposure to malicious content increases

Engineering Contradiction:
Improvehyperlink creationVSAvoidmalicious content exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system introduces an intermediary layer between the user's hyperlink creation action and the final landing page connection. By generating and comparing content signals with landing page signals, the system acts as a mediator that automatically validates whether the hyperlink is appropriate. This intermediary mechanism maintains ease of operation for legitimate uses while blocking malicious linkings, as the signal comparison process identifies harmful content without requiring complex user judgment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies preliminary anti-action by proactively detecting and preventing malicious hyperlinks before they can harm users. Through continuous monitoring of topic cohesion using signal analysis, the system identifies potential malicious linkings and takes remedial actions such as blocking the hyperlink or warning users. This preventive approach maintains ease of operation for legitimate content sharing while neutralizing harmful factors before they can affect users.

Inventive Principle:
Principle #9Preliminary anti-action

3Measurement precision

If topic cohesion monitoring is continuously performed, then topic drift detection is improved, but system complexity increases

Engineering Contradiction:
Improvetopic drift detection accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential features needed for topic cohesion monitoring by generating condensed content signals from posted content and corresponding landing page signals. Rather than analyzing entire pages or complex metadata, the system extracts key thematic signals and compares them directly. This extraction approach improves measurement precision for topic drift detection while minimizing system complexity, as the signal comparison process focuses on essential thematic elements rather than comprehensive content analysis.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems and method for determining a topic cohesion measurement between a content item and a hyperlinked landing page are presented. In one embodiment, a plurality of content item signals is generated for the content item and a corresponding plurality of signals are generated for the hyperlinked landing page. An analysis of the corresponding signals is conducted to determine a measurement of topic cohesion, a topic cohesion score, between the content item and the hyperlinked landing page. A cohesion predictor model is trained to generate the predictive topic cohesion score between an input content item and a hyperlinked landing page. Upon a determination that the topic cohesion score is less than a predetermined threshold, remedial actions are taken regarding the hyperlink of the content item. Alternatively, positive actions may be carried out, including promoting the content item to others, associating advertisements with the content item, and the like.
