Research profile
Output—
No output data is available yet. This axis would measure publication volume, venues, and authorship roles over time; the catalog currently holds only one reviewed 2026 paper, far too little to score.
Impact—
No citation data is available yet. Impact would measure citations, downstream adoption, and uptake of the warrant-based evaluation proposal; the arXiv preprint is too recent for usable citation counts in our snapshot.
Focus100/100
Focus scores 100/100 because the field distribution of the record is single-field: one paper, entirely in nlp / legal AI evaluation (raw fieldDist shows that field alone). With only one record behind it, the perfect specialization should be read as "no counter-evidence yet" rather than a mature research identity; later papers will show whether this legal-hallucination concentration holds.
Collaboration14/100
Collaboration scores 14/100 on the raw distinctCoauthors metric of 1: every catalogued work has a single co-author, Vered Shwartz, with no wider network in the snapshot. The low score reflects a two-person working pattern rather than a penalty for isolated authorship, and should move substantially as the co-author graph fills in. First-author positioning throughout the record fits a compact, senior-mentored team.
Activity—
No yearly activity data is available yet. This axis would track publishing cadence — papers per year and recent-year coverage — across the full record; the snapshot's single 2026 entry cannot establish any activity pattern.
Reproducibility20/100
Reproducibility scores 20/100, computed from reproMean = 20 over reproPapers = 1. The single reviewed paper is rated low repro-readiness: its evidence is a hand-written 18-output pilot with no real systems tested, and no code or benchmark release is documented in the catalog. As a position paper this is expected, but replication currently depends on artifacts the authors have not yet released.
Research summary
Maksym Taranukhin enters the Evolve catalog as a first-author NLP researcher working at the intersection of large language model evaluation and law. The reviewed record, the 2026 arXiv position paper 'Legal LLM Hallucination Should Be Evaluated as Failure of Legal Warrant', argues that hallucination in legal settings should not be reduced to factual or citation errors; instead, a system fails when it lacks the legal warrant — the claim-authority grounding that makes an assertion legitimate. The paper proposes a conceptual framework and roadmap connecting legal hallucination, claim-authority warrant, citation attribution, legal benchmarks, and retrieval-augmented generation. Evolve's verdict credits the framework and roadmap as strong while flagging that the evidence is a hand-written 18-output pilot with no real systems tested, yielding low repro-readiness. Bibliometrically, the snapshot is minimal: a perfect focus score of 100/100 rests on a single-field distribution (nlp / legal AI evaluation), the collaboration score of 14/100 reflects exactly one distinct co-author, Vered Shwartz, and reproducibility stands at 20/100 over one paper. Output, impact, and activity axes remain unscored because the underlying citation and volume data are not yet available. This makes the profile early-stage: an articulate, well-positioned research agenda whose empirical execution — and whether the warrant lens becomes a shared benchmark standard — remains to be demonstrated.
Collaboration pattern
The bibliometric record is deliberately small: exactly one distinct co-author, giving a collaboration score of 14/100. Vered Shwartz is the recurring co-author and anchors the senior side of a two-person pattern. All reviewed work positions Taranukhin as first author, consistent with a compact senior-junior collaboration rather than a large lab network; expect this axis to move substantially once further papers enter the record.

About this profile
This profile is AI-structured by Evolve.Pub from public bibliographic data (OpenAlex) and Evolve's own paper reviews. It is not written or endorsed by the researcher unless the profile is claimed. Radar dimensions are computed from real bibliometrics with fixed formulas — raw figures are shown alongside; missing dimensions mean insufficient data, never zero. Errors? Claim the profile to correct or hide it.
- Name-resolved profile: no ORCID, institution, or country is attached, so identity is matched from public bibliographic records only.
- Bibliometric scores come from a small OpenAlex-derived snapshot only, not from full Scopus or Web of Science coverage.
- Only one paper by this author has been reviewed in the Evolve catalog; every narrative rests on that single 2026 record.
- Output, impact, and activity axes are unscored because citation counts and yearly publication volumes are missing from the snapshot.
