MSLEF: Multi-Segment LLM Ensemble Finetuning in Recruitment
This addresses the problem of accurate resume parsing for recruitment automation, though it appears incremental as it builds on prior work (MLAR).
The paper tackles resume parsing in recruitment automation by introducing MSLEF, a multi-segment ensemble framework that fine-tunes LLMs for different resume sections, achieving up to +7% improvement in Recruitment Similarity over the best single model.
This paper presents MSLEF, a multi-segment ensemble framework that employs LLM fine-tuning to enhance resume parsing in recruitment automation. It integrates fine-tuned Large Language Models (LLMs) using weighted voting, with each model specializing in a specific resume segment to boost accuracy. Building on MLAR , MSLEF introduces a segment-aware architecture that leverages field-specific weighting tailored to each resume part, effectively overcoming the limitations of single-model systems by adapting to diverse formats and structures. The framework incorporates Gemini-2.5-Flash LLM as a high-level aggregator for complex sections and utilizes Gemma 9B, LLaMA 3.1 8B, and Phi-4 14B. MSLEF achieves significant improvements in Exact Match (EM), F1 score, BLEU, ROUGE, and Recruitment Similarity (RS) metrics, outperforming the best single model by up to +7% in RS. Its segment-aware design enhances generalization across varied resume layouts, making it highly adaptable to real-world hiring scenarios while ensuring precise and reliable candidate representation.
