UK-StatuteCorpus v1.0 (2020–2024): passage-level corpus, Eval100 evaluation dataset, and distillation set Open Access

UK-StatuteCorpus v1.0 is a passage-level corpus of UK statutory instruments from 2020–2024 (124,796 passages). The release also includes Eval100, a 100-query evaluation dataset with three graded relevant passages per query (rel=3/2/1) and rationales, and a distillation set of 5,221 query–passage examples with Voyage rerank-2.5 teacher scores for training neural rerankers. Contains public sector information licensed under the Open Government Licence v3.0 (legislation.gov.uk, The National Archives).

Research methods

We segmented statutory instruments into passages and associated each passage with structured metadata (e.g., year, legislation type, source URL). Eval100 was created by constructing 100 statutory questions and annotating three passages per query with graded relevance labels (3/2/1) and short rationales. A teacher reranker (Voyage rerank-2.5) was used to score query–passage pairs to form a 5,221-example distillation dataset for training smaller reranking models.
