Numerous HR applications are centered around resumes and job descriptions.
While they can benefit from advancements in NLP, particularly large language
models, their real-world adoption faces challenges due to absence of
comprehensive benchmarks for various HR tasks, and lack of smaller models with
competitive capabilities. In this paper, we aim to bridge this gap by
introducing the Resume-Job Description Benchmark (RJDB). We meticulously craft
this benchmark to cater to a wide array of HR tasks, including matching and
explaining resumes to job descriptions, extracting skills and experiences from
resumes, and editing resumes. To create this benchmark, we propose to distill
domain-specific knowledge from a large language model (LLM). We rely on a
curated skill-occupation graph to ensure diversity and provide context for LLMs
generation. Our benchmark includes over 50 thousand triples of job
descriptions, matched resumes and unmatched resumes. Using RJDB, we train
multiple smaller student models. Our experiments reveal that the student models
achieve near/better performance than the teacher model (GPT-4), affirming the
effectiveness of the benchmark. Additionally, we explore the utility of RJDB on
out-of-distribution data for skill extraction and resume-job description
matching, in zero-shot and weak supervision manner. We release our datasets and
code to foster further research and industry applications.
