Solution Overview

Problem

Current online search tools for topical advice require expertise in using search engines and produce voluminous results that are time-consuming to sift through, and static databases quickly become outdated, necessitating improved natural language-based search capabilities that can adapt and refine content continuously.

Innovation Solution

A machine learning facility that asks users questions, optimizes question selection, and provides decisions based on user feedback, allowing for continuous learning and refinement of advice through a dialog system that can adapt to user preferences and context.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional search engines are used to search for topical advice, then comprehensive results can be obtained, but the results are voluminous and time-consuming to sift through

Engineering Contradiction:
Improvesearch results volumeVSAvoidtime to sift through results
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system implements feedback loops where user interactions with advice content (views, clicks, selections) are continuously monitored and fed back into the machine learning models. This feedback mechanism allows the system to learn from user behavior patterns and progressively refine its advice generation, delivering more precise results over time without requiring users to manually filter through voluminous search results.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs self-service mechanisms through automated machine learning processes that continuously train and update the advice generation models without human intervention. The system automatically processes user feedback, adjusts its algorithms, and improves its performance autonomously, eliminating the need for manual curation or filtering of search results while maintaining high precision.

Inventive Principle:
Principle #25Self-service

2Reliability

If static databases of advice are used, then initial advice can be provided, but the advice quickly becomes outdated

Engineering Contradiction:
Improveadvice accuracyVSAvoidadvice freshness
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The system transitions from static databases to dynamic, adaptive advice generation through machine learning models that continuously evolve. The models are designed to adapt to changing user preferences, emerging topics, and evolving information patterns in real-time, ensuring advice remains current and relevant without relying on periodically updated static databases.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system maintains continuous learning and adaptation through ongoing processing of user feedback and interaction data. Rather than periodic updates, the machine learning models operate continuously to refine advice generation, ensuring the advice remains fresh and accurate by constantly incorporating new information and user preferences without interruption.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If machine learning optimizes question selection and decision-making, then personalized advice can be provided, but system complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs universal machine learning frameworks that handle multiple functions through a single integrated architecture. The same core learning models that optimize question selection also generate personalized advice, evaluate user feedback, and adapt to different topics and user preferences, reducing overall system complexity despite the breadth of capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces intermediary layers between user inputs and advice outputs, including question selection mechanisms and feedback processing intermediaries. These intermediaries manage the complexity by structuring the interaction flow and abstracting the underlying machine learning processes, making the system more manageable while maintaining high adaptability and personalization capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In embodiments of the present invention improved capabilities are described for a computer program product embodied in a computer readable medium that, when executing on one or more computers, helps determine an unknown user's preferences through the use of internet based social interactive graphical representations on a computer facility by performing the steps of (1) ascertaining preferences of a plurality of users who are part of an internet based social interactive construct, wherein the plurality of users become a plurality of known users; (2) determining the internet based social interactive graphical representation for the plurality of known users; and (3) inferring the preferences of an unknown user present in the internet based social interactive graphical representation of the plurality of known users based on the interrelationships between the unknown user and the plurality of known users within the graphical representation.
