Efficient Personalized Jargon Detection Makes Technical Documents Accessible Without Heavy Training

Making technical documents readable across different expertise levels presents a significant challenge. Readers from varying disciplinary backgrounds encounter field-specific terminology that can obscure meaning, yet personalizing models to detect and explain such jargon has traditionally demanded extensive manual annotation and substantial computational overhead.

A new research effort addresses this bottleneck by systematically investigating data-efficient approaches to personalized jargon detection that remain practical for real-world deployment.

Two Approaches to Personalization#

The work examines two core strategies for adapting models to individual readers' needs:

• Lightweight fine-tuning: Using Low-Rank Adaptation (LoRA) on open-source language models, which minimizes parameter updates while maintaining performance
• Inference-time personalization: Tailoring model responses through customized prompting without requiring retraining

Combining Limited Labels with Unlabeled Data#

To reflect realistic operational constraints, the researchers also explored hybrid approaches merging scarce human annotations with self-supervised learning from readers' own publication histories. This semi-supervised approach reduces the annotation burden while still leveraging available user-specific textual signals.

Impressive Performance Gains with Minimal Training Data#

The results demonstrate substantial advantages: their personalized LoRA approach surpassed GPT-4 using contextual prompts by 21.4% in F1 score and exceeded the strongest baseline by 8.3%. Perhaps most compellingly, the method achieved comparable outcomes using just 10% of the typical annotated training dataset, proving its viability for resource-constrained environments.

Practical Path Forward#

This study represents the first systematic exploration of efficient, low-resource personalization for jargon detection using open-source models, establishing a foundation for scalable, user-adaptive NLP systems that don't require prohibitive training investments.
