A verified identity foundation for the world's oncology experts. 为全球肿瘤专家建立可核验的身份底座。
AI too easily invents expert identities, blurs institutional affiliations, and fabricates credentials. TruthAnchor anchors every expert to real, external identifiers — ORCID, NPI, PubMed, ClinicalTrials.gov — so downstream knowledge grows on a traceable foundation of truth. AI 在生成癌症相关内容时，极易虚构专家身份、混淆机构归属、编造头衔与领域。TruthAnchor 用真实外部标识符体系——ORCID、NPI、PubMed、ClinicalTrials.gov——锚定每一位专家，使后续一切知识生长都有可追溯的真相边界。
m554 · Oncology Truth Anchor · an infrastructure layer, not a directory you browse — and not medical advice. m554 · 肿瘤真相锚盘 · 一个基础设施层，而非可浏览的名录——且不构成医疗建议。
Content is easy to generate. Trust is not.内容易生成，信任难建立。
Without an anchor没有锚点时
When an AI writes about cancer experts, identity is the first thing to break:当 AI 生成癌症专家相关内容时，最先崩坏的就是身份：
- Invented names and fabricated credentials that read as authoritative.凭空捏造的姓名与头衔，读起来却像权威。
- Real people attached to the wrong institution or specialty.真实的人被挂到错误的机构或专科。
- Claims with no source URL — impossible to check, easy to trust.没有来源 URL 的论断——无法核实，却容易被采信。
- A single dubious source treated as ground truth.单一可疑来源被当作事实基准。
With TruthAnchor有锚盘之后
A multi-anchor truth model binds each expert to authoritative identifiers before knowledge is allowed to grow:"多锚点真相模型"在知识生长之前，先把每位专家绑定到权威标识符：
- Identity resolved against ORCID and NPI, not guessed.身份对齐 ORCID 与 NPI，而非猜测。
- Evidence collected from PubMed, ClinicalTrials.gov and official pages.证据取自 PubMed、ClinicalTrials.gov 与官方主页。
- Every record scored, graded L0–L3, and audited.每条记录评分、分级 L0–L3、并留审计日志。
- Ambiguous cases routed to a human review queue.存疑记录进入人工复核队列。
A pipeline that anchors before it asserts.先锚定、再断言的流水线。
Six deterministic stages take a candidate name and either produce a source-backed, graded record — or hold it for human review.六个确定性阶段，把一个候选姓名变成有来源支撑、分级明确的记录——否则留待人工复核。
Candidate generation候选生成
Discover potential experts through OpenAlex and PubMed within a target cancer domain.在目标癌症领域内，经 OpenAlex 与 PubMed 发现潜在专家。
Identity resolution身份锚定
Bind the candidate to ORCID and NPI identifiers with strict validation rules.以严格校验规则，将候选人绑定到 ORCID 与 NPI 标识。
Evidence collection证据收集
Gather corroborating evidence from PubMed, ClinicalTrials.gov and official homepages.从 PubMed、ClinicalTrials.gov 与官方主页收集佐证。
Scoring & grading评分与分级
Compute a credibility score from identifiers, papers, trials and institution — then assign L0–L3.按标识符、论文、试验、机构计算可信分，再赋 L0–L3。
Store & audit入库与审计
Persist the record with a full audit trail — every field references where it came from.带完整审计链入库——每个字段都指向其来源。
Human review人工复核
Send borderline or high-stakes records to a review queue; people make the final call.存疑或高风险记录进入复核队列，最终由人裁定。
Four tiers, from unverified to strongly trusted.四级信任：从未核验到强可信核心。
A record only climbs a tier when it meets that tier's evidence bar. Nothing skips a step.只有满足对应门槛，记录才升一级。绝不跳级。
Not all sources carry the same weight.不是所有来源都同等分量。
Sources are tiered by authority. The rule to enter the core: at least one Tier-A anchor, and at least two Tier-A/B sources together.来源按权威分层。入核心的硬规则：至少 1 个 A 层锚点，且 A/B 层合计 ≥ 2。
Primary anchors主锚点
Decide whether a record can enter the core at all.决定记录能否入核心层。
Cross-validation交叉验证
Supplement and disambiguate — never the final judge.补充与去歧义——但不做终判。
Discovery only仅作发现
Used to find candidates, never to certify them.只用于发现候选人，绝不用于认定。
The boundaries that keep it honest.让它保持诚实的边界。
Built for teams who can't afford to be wrong about identity.为"身份不容出错"的团队而建。
AI & content platformsAI 与内容平台
Ground generated oncology content in verified expert identities, so citations point to real people.让生成的肿瘤内容落在已核验的专家身份上，引用指向真实的人。
Researchers & curators研究者与策展人
Start from a source-backed roster instead of hand-checking every affiliation and identifier.从有来源支撑的名册出发，无需逐一手工核对机构与标识。
