JurisRank — Argentine Jurisprudential Authority Analysis

What JurisRank Is

JurisRank is a computational tool for measuring the authority of Argentine

court decisions through citation network analysis. Its methodology is

peer-reviewed and published in the Journal of Computational Law and

Legal Technology:

> Network Analysis and Semantic Measurement of Argentine Supreme Court

> Jurisprudence (1922–2025)." *Journal of Computational Law and Legal

> Technology.* DOI: 10.47852/bonviewJCLLT62027951

Three Algorithms

| Algorithm | Purpose |

|-----------|---------|

| JurisRank | PageRank + temporal decay — recent citations weighted higher |

| RootFinder | Ancestral Borrowing Analysis Network — traces doctrinal genealogy |

| Legal-Memespace | Principal Component Analysis — maps multidimensional doctrine |

Coverage

• Argentine Supreme Court (CSJN) — 1922 to present
• National and federal courts of appeals (Cámaras nacionales y federales)
• Selected provincial supreme courts
• Relevant international precedents cited by Argentine courts

Authority Score Interpretation

| Score | Meaning | Recommendation |

|-------|---------|---------------|

| > 0.8 | Leading case — highest citation authority | Cite first, with score |

| 0.6–0.8 | Widely cited — strong precedential weight | Cite with score |

| 0.4–0.6 | Relevant — moderate authority | Cite with note |

| < 0.4 | Limited authority — outlier or isolated | Orientation only |

| Not found | No network presence detected | Declare absence of precedent |

Use Cases

1. Selecting case law for briefs and memos

When multiple cases address the same issue, JurisRank identifies which

carry the most authority in the citation network → cite the most

influential first, in ranked order.

2. Doctrinal evolution analysis

Trace how CSJN or appellate court doctrine evolved on a specific topic.

Identify whether the most recent decision continues or breaks from prior

doctrine.

3. Adversarial jurisprudential due diligence

Verify whether precedents cited by opposing counsel are genuinely

authoritative or low-influence outliers.

4. Constitutional drift detection

Detect shifts in citation patterns that signal doctrinal erosion or

realignment — original application from the JCLLT paper.

Workflow

1. Identify topic or specific cases to analyze
2. Query JurisRank API:
   GET  https://api.jurisrank.com/v1/cases?query=<topic>
   POST https://api.jurisrank.com/v1/analyze-authority {"case_id": "..."}
3. Interpret Authority Score and citation network position
4. Apply RootFinder for genealogy if doctrinal evolution is needed
5. Produce ranked analysis with citation recommendations

Anti-Hallucination Rules

JurisRank implements groundedness verification per the Stanford Legal AI

Benchmark (Magesh et al., 2024):

Before including any case in the analysis:

• Confirm Authority Score > 0.0 (case exists in the network)
• Verify jurisdiction matches the forum of the matter
• Check temporal decay: has a more-cited posterior decision superseded it?
• Verify the case actually supports the proposition — not just addresses the topic

**Never cite a case not found in the JurisRank network without explicitly

declaring it as unverified.**
