Unlocking Semantic Textual Similarity in Slovak
This paper addresses the significant challenge of Semantic Textual Similarity (STS) in low-resource languages, specifically Slovak. It provides a comprehensive comparative evaluation of traditional STS algorithms, custom machine learning models, and advanced third-party deep learning tools. The research highlights the trade-offs between accuracy, computational cost, and interpretability, offering practical guidance for implementing STS solutions in Slovak-speaking contexts.

Machine Learning Models
Third-Party Tools & Transformers
Traditional STS methods, including string-based, statistical, and knowledge-based algorithms, are foundational. String-based methods focus on lexical structure (e.g., Levenshtein, Jaccard), while statistical methods leverage large text corpora to capture semantic associations (e.g., HAL, FastText embeddings). Knowledge-based approaches utilize semantic networks like WordNet to represent word meanings.
For Slovak, term-based string algorithms like Ochiai Coefficient (0.580) performed best among traditional methods, outperforming character-based, statistical (except for OpenAI word embeddings), and knowledge-based approaches.
Custom Machine Learning (ML) models were trained using outputs from traditional STS algorithms as features. Regression models, including Linear, Bayesian Ridge, SVR, Decision Tree, Random Forest, Gradient Boosting, and XGBoost, were evaluated. Gradient Boosting Regression (0.685) and XGBoost (0.678) demonstrated superior performance, leveraging the feature engineering from traditional algorithms effectively. Hyperparameter tuning and feature selection were optimized using Artificial Bee Colony (ABC) algorithm.
Advanced third-party tools and pretrained models, including OpenAI embeddings, GPT-4, NLPCloud, and fine-tuned SlovakBERT, were assessed. NLPCloud achieved the highest Pearson score (0.824), using a fine-tuned sentence-BERT model. GPT-4 also showed strong results (0.780), outperforming embedding models. Fine-tuned SlovakBERT (0.7537) performed comparably to the best OpenAI embedding models, highlighting its effectiveness for domain-specific tasks.

Impact of Domain-Specific Fine-Tuning
The evaluation of the open-source SlovakBERT model demonstrates the significant advantage of domain-specific fine-tuning. While general embedding models like OpenAI performed well, fine-tuning SlovakBERT on a portion of the STS Benchmark dataset allowed it to achieve a Pearson correlation of approximately 0.75. This performance is comparable to the best OpenAI embedding models, indicating that tailored training for specific languages and tasks can yield state-of-the-art results without relying solely on large commercial APIs. This approach offers a cost-effective and adaptable solution for under-resourced languages.
Conclusion: Fine-tuning localized models provides a viable path to high-performance STS for Slovak, offering a balance between accuracy and resource efficiency.
