Solution Overview

Problem

Existing methods for categorizing news articles struggle to accurately determine the geographical scope of interest and topic classification, especially with the vast number of news sources and the complexity of content analysis, often relying on expensive and cumbersome editorial processes.

Innovation Solution

A method that groups news articles into clusters based on common topics, uses metadata and user interaction data to determine the geographical scope of interest, and classifies articles as news or not-news, general news, or topical news, using machine learning algorithms and social network analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If editorial processes are used to determine topic and geographical scope of news articles, then accuracy of classification is improved, but cost and time consumption increase significantly

Engineering Contradiction:
Improveclassification accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary automated classification of news articles into topics and geographical scopes using machine learning models before editorial review. This pre-processing step filters out clearly classified articles, allowing editors to focus only on ambiguous cases and significantly reducing overall processing time while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

An automated machine learning classification system serves as an intermediary between raw news articles and editorial review. This intermediary performs initial categorization based on content analysis, providing editors with pre-classified articles that require minimal intervention, thus reducing both time consumption and editorial workload.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the number of news categories and topics for filtering is increased to cover all news sources, then comprehensiveness of news coverage is improved, but difficulty of filtering news for users increases

Engineering Contradiction:
Improvenews coverage comprehensivenessVSAvoidfiltering complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the vast number of news categories into hierarchical groups (e.g., major topics like Politics, Sports, Entertainment, with sub-topics nested within). This segmentation allows users to navigate broad categories first and drill down to specific topics of interest, making the filtering process manageable despite the large number of available categories.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The classification system uses a universal set of high-level topic categories that can accommodate diverse news sources and content types. This multi-functional category structure allows the same filtering framework to handle various news sources uniformly, reducing the apparent complexity for users while maintaining comprehensive coverage.

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

3Measurement precision

If content analysis is performed to determine topic of news articles, then topic classification accuracy is improved, but inability to determine geographical scope of interest persists

Engineering Contradiction:
Improvetopic classification accuracyVSAvoidgeographical scope information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system merges multiple data sources including article content, metadata, publisher information, and user interaction data to determine both topic classification and geographical scope of interest. By combining these different information types, the system overcomes the limitation of content analysis alone and successfully infers geographical relevance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system adds a geographical dimension to the traditional topic classification by analyzing spatial information from multiple sources (publisher location, mentioned locations in content, user demographics). This dimensional expansion allows simultaneous determination of both topic and geographical scope without compromising either accuracy.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Measurement precision

If manual editorial analysis is used for each news article, then accuracy of determining news category and geographical scope is improved, but expense and cumbersome nature of the process increase

Engineering Contradiction:
Improveclassification accuracyVSAvoidprocess efficiency
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The system implements self-service automated classification using machine learning models that independently analyze news articles and assign topic categories and geographical scopes without requiring manual editorial intervention for each article. This self-service approach maintains high accuracy while dramatically improving process efficiency and reducing costs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical editorial process (human analysts manually reviewing each article) with an automated electronic classification system based on machine learning and content analysis. This substitution eliminates the cumbersome nature of manual processing while maintaining or improving classification accuracy through consistent algorithmic application.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Methods for categorizing news are presented. One method groups articles into clusters that share a common topic. A first category is identified for each article that indicates if the article is news or not. Further, the method includes an operation for determining use data for each article that has information about people that have accessed or referenced the article. Additionally, the method includes an operation for combining the use data and the first category for all the articles in each cluster to determine the geographical scope of interest for the cluster. The use data and the first category are combined for all the articles in each cluster to determine a second category for each article that indicates if the article is general news, topical news, or not news. The articles are presented to the user based on the geographical scope of interest, the second category, and the attributes of the user.
