Entity Linking in the Job Market Domain
CoRR(2024)
摘要
In Natural Language Processing, entity linking (EL) has centered around
Wikipedia, but yet remains underexplored for the job market domain.
Disambiguating skill mentions can help us get insight into the current labor
market demands. In this work, we are the first to explore EL in this domain,
specifically targeting the linkage of occupational skills to the ESCO taxonomy
(le Vrang et al., 2014). Previous efforts linked coarse-grained (full)
sentences to a corresponding ESCO skill. In this work, we link more
fine-grained span-level mentions of skills. We tune two high-performing neural
EL models, a bi-encoder (Wu et al., 2020) and an autoregressive model (Cao et
al., 2021), on a synthetically generated mention–skill pair dataset and
evaluate them on a human-annotated skill-linking benchmark. Our findings reveal
that both models are capable of linking implicit mentions of skills to their
correct taxonomy counterparts. Empirically, BLINK outperforms GENRE in strict
evaluation, but GENRE performs better in loose evaluation (accuracy@k).
