Traditional\nrule-based systems are difficult to scale in large and dynamic data environments. To\naddress this, the study evaluates three LLMs: GPT-4 Turbo, Gemini 1.5 Pro, and Claude\n3.7 Sonnet, using three prompting strategies: zero-shot, few-shot, and prompt-chaining.\nA total of 216 rule sets were generated from metadata and profiling inputs and evaluated\nby domain experts. Results show that prompt-chaining significantly improves rule quality\nover standalone prompting strategies, while model choice has a minor impact. The\nbest-performing combination (Claude with prompt-chaining) achieved high-quality\noutputs.\nThese findings demonstrate that GenAI can support scalable and adaptive DQ rule\ngeneration when paired with effective prompt design, offering a practical solution for\nenterprise data monitoring.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by jyx lomake-julkaisija (jyx-julkaisija.group@korppi.jyu.fi) on 2025-06-02T12:06:50Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-06-02T12:06:50Z (GMT).
