Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for analyzing user preferences in electronic commerce struggle to quickly and accurately provide customized content due to the inclusion of unnecessary information in web documents, which reduces analysis accuracy and requires separate management by each web server.

Innovation Solution

A user-customized content providing system that collects and analyzes user preference information using anchor tag and form tag information, allowing web servers to request and rank content based on user profiles with weighted keywords, excluding stop words and dynamically updating preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If all contents of web documents are analyzed to study user preference, then the analysis comprehensiveness is improved, but the analysis time and computational resources increase significantly

Engineering Contradiction:

Improveuser preference analysis accuracyVSAvoidanalysis time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts only the necessary tag information (anchor tags and form tags) from web documents to analyze user preference, rather than analyzing all contents. This extraction approach maintains analysis accuracy by focusing on meaningful user interaction indicators while significantly reducing the volume of data to be processed, thereby resolving the contradiction between comprehensive analysis and analysis time.

Inventive Principle:

Principle #2Taking out (Extraction)

2Quantity of substance

If web documents including unnecessary information are analyzed, then the data volume for analysis is improved, but the accuracy of user interest analysis deteriorates

Engineering Contradiction:

Improvedata volumeVSAvoiduser interest analysis accuracy

Core Design Contradiction:

Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent extracts only relevant tag information (anchor tags and form tags) from web documents, filtering out unnecessary information such as advertisements, company profiles, and copyright information. This selective extraction maintains data volume sufficient for accurate analysis while eliminating noise that would degrade analysis accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different analysis treatments to different parts of web documents by focusing specifically on tag elements rather than uniform analysis of all content. Anchor tags and form tags are identified as having higher informational value for user preference analysis, so they are extracted and analyzed with higher priority, while other parts are excluded from detailed analysis.

Inventive Principle:

Principle #3Local quality

3Device complexity

If user preference information is managed separately by each web server, then the system complexity is reduced, but the ability to provide unified personalized service across multiple servers deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidpersonalized service capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements a centralized user preference management system that serves multiple web servers uniformly. The preference information collected from user interactions is stored centrally and can be accessed by any web server in the system, enabling consistent personalized service across different servers while maintaining manageable system complexity through standardized protocols and data structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If traditional user preference collection methods are used, then the implementation simplicity is improved, but the ability to capture dynamically changing user preferences deteriorates

Engineering Contradiction:

Improveimplementation simplicityVSAvoiddynamic preference capture capability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a feedback mechanism that continuously monitors user interactions with web documents (clicking anchor tags, submitting form tags) and updates user preference information in real-time. This feedback loop enables the system to capture dynamically changing user preferences while maintaining implementation simplicity by leveraging existing web technologies and standardized data collection methods.

Inventive Principle:

Principle #23Feedback
