1Ease of operation
If conventional text clustering methods are used, then text can be organized into clusters, but the clusters become imbalanced and disjointed, lacking coherence and readability
Solution Approach 1:
The patent applies parameter changes by transforming text units into numerical vectors using embedding models, then applying multiple clustering algorithms (K-means, hierarchical, DBSCAN) with different parameters to generate diverse cluster configurations. The system evaluates clusters using multiple metrics including coherence, balance, and readability scores, selecting the optimal clustering configuration that balances these competing requirements.
Solution Approach 2:
The system employs multiple clustering algorithms and evaluation metrics to simultaneously optimize for both cluster balance and readability. The multi-metric evaluation framework assesses clusters on multiple dimensions (coherence, balance, readability) and combines these assessments to select the best clustering result, making the system universal in handling different text properties simultaneously.
2Loss of time
If text is organized into clusters to improve readability, then comprehension time decreases, but conventional methods fail to optimize multiple text properties simultaneously
Solution Approach 1:
The system transforms text into numerical representations and applies multiple clustering algorithms with different parameters to optimize various text properties simultaneously. By changing the parameter space and evaluating multiple clustering configurations, the system can adapt to optimize different text properties including coherence, balance, and readability together rather than sequentially.
Solution Approach 2:
The patent introduces additional evaluation dimensions by implementing a multi-metric framework that assesses clusters on multiple properties simultaneously (coherence, balance, readability). This multi-dimensional evaluation approach allows the system to optimize across multiple text properties at once, rather than focusing on a single dimension.
3Measurement precision
If multiple clustering algorithms are evaluated, then optimal clustering can be selected, but computational complexity increases
Solution Approach 1:
The system segments the clustering evaluation process into distinct stages: generating clusters using multiple algorithms, evaluating each cluster on multiple metrics, and selecting the optimal configuration. This segmentation allows the complex task of multi-property optimization to be broken down into manageable steps, reducing overall system complexity while maintaining measurement precision.
Solution Approach 2:
The system implements feedback loops where cluster evaluations on multiple metrics feed back into the selection process. The multi-metric evaluation framework provides feedback on cluster quality across different dimensions, allowing the system to iteratively select and refine clustering configurations to achieve optimal results without requiring excessive computational resources.
Data Source
AI summary
Implementations generally relate to text clustering with heuristic and multi-metric control. In some implementations, a method includes receiving an electronic source document containing text. The method further includes dividing the text into text units, encoding the text units, and transforming the text units into numerical values. The method further includes generating a graph of the text units based on the numeric values, where the graph includes nodes corresponding to the text units and edges corresponding to pairs of the text units. The method further includes ordering the text units into text clusters based on the graph of the text units. The method further includes generating an electronic target document that presents the text clusters based on one or more preference heuristics.
