Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large language models are used to identify important and urgent news across large datasets, then identification accuracy is improved, but processing cost and time consumption increase significantly
Solution Approach 1:
The patent segments the news identification task into multiple stages: initial filtering using traditional NLP techniques, clustering similar news articles together, and then applying LLMs only to representative samples from each cluster. This segmentation reduces the overall processing time while maintaining identification accuracy by limiting expensive LLM computations to essential cases only.
Solution Approach 2:
The patent applies partial action by using LLMs selectively rather than on all news articles. Traditional NLP methods are applied to the entire dataset first, and LLMs are reserved for partial processing of clustered representatives, achieving sufficient accuracy without the excessive time cost of universal LLM application.
2Measurement precision
If large language models are used to identify important and urgent news across large datasets, then identification accuracy is improved, but processing cost increases significantly
Solution Approach 1:
The patent segments the processing workload to apply cost-effective traditional NLP methods to the bulk of articles and reserves expensive LLM resources for clustered representatives only. This segmentation dramatically reduces processing cost while preserving identification accuracy through the hierarchical approach.
Solution Approach 2:
The patent creates clusters of similar news articles where traditional NLP processing results can be copied and applied to multiple articles within a cluster. This copying approach reduces the need for expensive LLM processing on every individual article, lowering overall processing costs while maintaining consistent identification quality.
3Productivity
If traditional clustering methods are used to group news articles, then processing efficiency is improved, but the ability to capture nuanced similarities decreases
Solution Approach 1:
The patent segments the similarity detection process into two levels: traditional clustering for broad categorical groupings and LLM-based analysis for nuanced similarity assessment within clusters. This segmentation allows traditional methods to handle the bulk of efficiency-critical operations while LLMs refine similarity detection where precision matters most.
Solution Approach 2:
The patent introduces an intermediary clustering stage between traditional NLP processing and LLM analysis. This intermediary step groups articles by obvious similarities first, then allows LLMs to act as mediators for detecting more nuanced similarities within each cluster, combining the efficiency of traditional methods with the precision of LLMs.

AI summary
A method for automatically identifying important and urgent news (IUN) in a large set of data comprises obtaining the large set of data in a textual-format, the large set of textual-data data contain a plurality of individual texts; clustering the textual-format data into a plurality of clusters; for each cluster, calculating the distances to all other clusters in the plurality of clusters and from those calculated distances determining a radius and a median of those calculated distances and then obtaining a difference between the radius and the median; and using the difference to identify important and urgent news in the large set of data.
