An NLP-Driven Framework for Curriculum-Labor Market Alignment: Schema-Constrained LLM Extraction, ESCO-Anchored Semantic Matching, and Multi-Dimensional Gap Quantification

Summary

A novel four-stage NLP framework addresses curriculum-labor market alignment by combining schema-constrained LLM extraction with semantic matching and multi-dimensional gap quantification. This framework utilizes a two-model frontier-LLM ensemble prompted against a JSON Schema-enforced seven-slot competency formalism, followed by Sentence-BERT (SBERT) alignment with an eleven-domain ESCO v1.2.1 controlled vocabulary. It incorporates a two-tier adjudication protocol for inter-model disagreements and a verification mechanism using Cohen's kappa, schema conformance, and document-level completeness audits. Applied to the ABET-accredited BSc Computer Science program at the United Arab Emirates University, the pipeline extracted 400 competency records from 85 courses for the 2025-2026 study plan. These were aligned with 30 job postings (483 requirement clauses) at an SBERT cosine threshold of 0.50. The extractor achieved a Cohen's kappa of 0.79 on the skill slot, with 100% schema conformance. The analysis revealed supply-demand gaps of 25.0% in general skills and 13.8% in algorithms, with a 1.8% gap in AI and data science.

Key takeaway

For Research Scientists or NLP Engineers tasked with curriculum-labor market alignment, this framework offers a robust approach to quantify skill gaps. You should consider implementing schema-constrained LLM extraction combined with semantic matching against controlled vocabularies like ESCO. This method provides high reliability and clear metrics, enabling you to identify specific supply-demand imbalances, such as the 25.0% gap in general skills, to inform targeted program adjustments.

Key insights

An NLP framework uses LLMs and semantic matching to quantify curriculum-labor market competency gaps with high reliability.

Principles

• Schema-constrained LLM prompting enhances extraction reliability.
• Semantic alignment with controlled vocabularies grounds competencies.
• Multi-tier verification ensures data quality and completeness.

Method

The framework involves schema-constrained LLM extraction, SBERT alignment with ESCO v1.2.1, a two-tier adjudication protocol, and verification via Cohen's kappa, schema conformance, and document-level completeness audits.

In practice

• Use a two-model LLM ensemble for robust competency extraction.
• Anchor extracted skills to ESCO v1.2.1 for standardized alignment.
• Implement Cohen's kappa for per-slot extraction reliability checks.
