Methodology

Show the relationship. Preserve the uncertainty.

SentinelGraph is designed to make public-record connections easier to inspect, not to convert incomplete data into a conclusion. The release, match basis, graph edge, priority signal, and source trail remain distinct.

Four release gates

GATE 01

Identity

Validate NPIs; distinguish exact-NPI associations from name-and-state candidates; suppress ambiguous names.

GATE 02

Structure

Require one NPI root, valid node types, no orphan edges, and no generic role-label nodes.

GATE 03

Source

Require a source-verification flag on every edge and trace sampled edges to exact source fields.

GATE 04

Interpretation

Describe a relationship literally and include ordinary alternative explanations.

Validation program

Broader healthcare scoring remains under evidence-first validation.

SentinelGraph is evaluating expanded enrollment, ownership, utilization, payment, quality, and public-outcome data using time-correct source cutoffs. Known public actions are kept separate from prospective scoring, identity links require documented evidence, and quantified effectiveness claims will not be published until the defined retrospective gate and independent review are complete.

Identity lanes

Exact is not the same as candidate.

Exact-NPI match

A selected source record and provider root are connected through a validated NPI field. The source date and NPI remain visible.

Name-and-state candidate

Normalized name and state produce a review candidate without an exact shared NPI. Identity must be resolved independently before reliance.

Relationship semantics

Edges describe fields, not intent.

SUBJECT_OF: A source lead is linked to its selected provider root.
SHARES_ADDRESS: Two provider roots contain the same normalized source address.
SHARES_PHONE: Two provider roots contain the same normalized source telephone field.
AUTHORIZED_OFFICIAL_OF: An official is named in the provider source record.

Review-priority scoring

A priority score combines displayed identity, source, graph, and recency features to order a bounded lead queue for human review. It is not a fraud-risk score, probability, finding, prediction, or recommendation for referral, prosecution, enforcement, eligibility, credit, or another adverse action. Higher priority means only that the displayed features caused the record to appear earlier in the review queue.

Important disclaimer: SentinelGraph is an investigative lead source based on public records. A lead, priority score, shared address, telephone number, official, or graph edge is not a finding or accusation of fraud, wrongdoing, liability, intent, eligibility, or regulatory status. Verify the original sources and make an independent human assessment. Sentinel Graph LLC does not provide legal advice or create a professional relationship through this site.
