Cross-Jurisdictional Legal Citation Coupling — Ukrainian data & tools Reproducibility artifacts for the paper "Bibliographic Coupling as a Cross-Jurisdictional Evaluation Framework for Legal Case Retrieval: Civil-Law and Common-Law Citation Graphs Compared." The paper compares a civil-law citation graph (Ukrainian, from the EDRSR state court-decision registry) with a common-law one (Canadian, from the COLIEE 2026 Task 1 corpus) under a single coupling / co-citation / temporal… See the full description on the dataset page: https://huggingface.co/datasets/overthelex/crossjur-citation-coupling.
Correct the Cite(d) claim (both sides are lower bounds), report gold-set sizes, add BC diagnostics and the Reachability Gain measure
UALB-23: domain-matched (administrative) UA coupling — density 0.110 (~46x CA), confound ruled out; paper 16pp
UALB-22: BM25 baseline (vectorized) + bootstrap CIs + UA-CA significance; paper updated
Add RQ4: coupling temporal decay + coupling/co-citation orthogonality (paper 15pp, +tools/data)
Add UA Cite(d) map for the coupling metrics
Add Yoshioka (Sekiguchi et al.) Extended-Precision/Coverage results + Cite(d) map + updated retrieval tool
Add RQ3: cross-jurisdictional application of the Sekiguchi-Yoshioka-Kwan coupling framework
Disable dataset viewer (repo holds artifacts, not a tabular dataset)
Draft: remove author line (authorship TBD); soften README citation
Add paper (PDF + LaTeX source)
Add cross-jurisdictional coupling tools + UA-derived data (reproducibility)
