About the Research
This research paper presents a comparative analysis of three prominent topic detection methods—Sklearn LDA, KeyBERT with KMeans, and TF-IDF with KMeans—specifically applied to news corpora. It introduces a unified framework for data preprocessing, model application, keyword extraction, and visual assessment.
The study highlights how each method prioritizes different aspects of text analysis, from probabilistic associations in LDA to semantic embeddings in KeyBERT and statistical significance in TF-IDF. Findings offer practical recommendations for enterprises seeking to enhance content curation, opinion tracking, and trend forecasting.
Methodology at a Glance
The study employs a robust methodology, starting with the HuffPost News Category Dataset. After comprehensive preprocessing including lemmatization, three distinct topic modeling approaches were applied:
- Sklearn LDA: A probabilistic model for latent topics, excelling in organized topic divisions.
- KeyBERT + KMeans: Leverages BERT embeddings for semantic richness, ideal for capturing nuanced themes in shorter texts.
- TF-IDF + KMeans: A frequency-based approach offering computational efficiency for large datasets.
Evaluation focused on keyword relevance, topic distribution, and consistency, quantified by Jaccard similarity and coherence scores (C_v measure).
Key Findings & Visualizations
Visual aids such as word clouds, frequency heatmaps, cluster bar charts, and Jaccard similarity matrices were instrumental in evaluating the methods:
- Word Clouds: Highlighted how Sklearn LDA identified general high-frequency words, KeyBERT+KMeans captured descriptive phrases, and TF-IDF+KMeans focused on prominent terms.
- Coherence Scores: KeyBERT demonstrated superior semantic coherence (0.52 C_v), followed by LDA (0.47) and TF-IDF (0.41).
- Cluster Distribution: Sklearn LDA and KeyBERT+KMeans showed more uniform distributions, while TF-IDF+KMeans exhibited skewness towards dominant topics.
- Jaccard Similarity: Indicated high overlap between LDA and TF-IDF, but low overlap with KeyBERT, suggesting its unique semantic focus.
Strategic Applications for Your Business
The insights from this research can be directly applied to various enterprise functions:
- Content Curation: Automate topic identification to enhance news aggregation, content tagging, and recommendation systems.
- Opinion Tracking: Monitor public sentiment and emerging discussions around specific topics or brands in real-time.
- Market Intelligence: Identify nascent trends and shifts in news coverage to inform strategic decision-making and competitive analysis.
- Information Retrieval: Improve the precision and recall of internal document search and knowledge management systems by accurately categorizing content.
KeyBERT's Semantic Coherence
0.52 Average Coherence Score (C_v)KeyBERT consistently achieved the highest average coherence score (0.52 C_v), indicating its superior ability to capture semantically meaningful and nuanced topics from news data.
