Interactive Ring Interface for User Interest Model Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adaptive portals lack user understanding and control over personalization processes, leading to negative user experiences due to hidden adaptation mechanisms and limited interaction with user interest models.
Innovation Solution
An interactive graphical user interface that visualizes user interest models using a circular sector ring representation, allowing users to modify and interact with their interest degrees and semantic types, enabling zooming, filtering, and grouping functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the adaptation mechanism is hidden from users, then the portal can automatically personalize content without user intervention, but users lose understanding and control over the personalization process
Solution Approach 1:
The patent introduces a user interest model as an intermediary component that mediates between the automatic adaptation system and the user. This model makes the hidden adaptation mechanisms visible and interpretable to users, allowing them to understand how personalization works while maintaining automated operation. The user interest model serves as a bridge that translates system decisions into understandable user preferences.
Solution Approach 2:
The patent implements feedback mechanisms that allow users to view, modify, and control their user interest models. Users receive feedback about how the system adapts content based on their interests, and they can actively adjust their models to control personalization behavior. This feedback loop resolves the contradiction by maintaining automation while giving users direct control and understanding.
2Device complexity
If the user model and domain knowledge model are hidden, then the system can maintain simplicity and automation, but users experience limited control and may receive irrelevant recommendations
Solution Approach 1:
The patent segments the complex adaptation system into manageable components, specifically the user interest model and domain knowledge model. By segmenting and making these models accessible to users through the graphical interface, the system maintains its automated functionality while providing users with control over specific aspects of adaptation. Users can modify their interest models without needing to understand the entire complex system.
3Extent of automation
If users cannot view and modify their user model, then the system maintains automation and simplicity, but users cannot correct wrong assumptions about their interests
Solution Approach 1:
The patent enables users to perform self-service by allowing them to directly view and modify their own user interest models. Users can correct inaccurate assumptions about their interests, add new interests, and adjust existing ones. This self-service capability maintains the automated detection functionality while significantly improving the reliability and accuracy of the interest representation through user validation and correction.

AI summary
A computer method and system for interactive visualization and modification of a user interest model via an interactive graphical user interface is described. The method and system comprise displaying at least one keyword in a circular sector on a ring on the interactive graphical user interface, wherein the keyword represents an interest of the user interest model, wherein a radial position of the keyword on the ring represents a degree of interest stored as part of the user interest model, and wherein the circular sector represents a semantic type of the user interest model. The method and system further enable a user to actively influence the modeling server and graphically modify/change the degree of interest via an interaction component of the interactive graphical user interface.
