# AISignal

> AISignal is an evidence-chain-first AI intelligence publication. It tracks global AI news, models, agents, papers, open-source projects and industry events, then normalizes, deduplicates, clusters, verifies and publishes them in Chinese and English.
> AISignal separates source trust, verification status, confidence, importance, heat and novelty. Community activity is a discovery and heat signal, not factual evidence. Each public event preserves links to its supporting sources. AI assists drafting, translation, clustering and QA; humans retain responsibility for consequential publishing, corrections, retractions and source permissions.

## 中文说明

> AISignal 是一家以证据链为先的双语 AI 情报出版平台：持续追踪全球 AI 新闻、模型、智能体、论文、开源项目与产业事件，经归一化、去重、聚类、验证后以中英双语发布。平台区分来源等级、验证状态、置信度、重要性、热度与新颖度六个维度；社区信号只用于发现与热度，不作为事实证据。AI 参与起草、翻译、聚类与质检，重大发布、更正、撤稿与来源许可由人工负责。

## Machine field reference

- `canonical_language`: original language of the item (`en`/`zh`). `_zh` fields carry Chinese translations.
- `available_locales` / `indexable`: languages with real publishable content. Only these appear in hreflang and sitemaps; a missing locale means the page is still readable but is not a complete translated edition.
- `content_updated_at`: last substantive change (title, summary, body, evidence, verification state, correction, retraction, primary source). Heat, views and score refreshes never move it.
- `status`: 200 normal · 308 permanent redirect (merged or renamed; one hop) · 410 permanently removed.
- `sources[]`: name, original item URL, publication time, grade, primary-evidence flag; permission-restricted metadata is omitted.

## Citation guidance

Prefer the canonical event, story, model, paper or topic URL. Attribute claims to AISignal only when they are AISignal analysis; when AISignal exposes an original source, cite that primary source as well. Preserve verification status and uncertainty. Do not represent community heat, confidence or importance scores as facts about the underlying world.

## 引用规范（中文）

优先引用事件、报道、模型、论文或专题的规范 URL（canonical）。只有属于 AISignal 分析的论断才署名 AISignal；凡平台给出原始来源的，应同时引用该一手来源。保留验证状态与不确定性标注，不得把热度、置信度或重要性评分当作对外部事实的陈述。

## 机器字段说明（中文）

- `canonical_language`：条目原文语言（en/zh）；`_zh` 字段是中文译文。
- `available_locales` / `indexable`：真实可用的语言版本；只有这些语言进入 hreflang 与 sitemap。不在其中表示该语言页面仍可阅读，但不构成完整译文版。
- `content_updated_at`：最后**实质**变化时间（标题/摘要/正文/证据/验证状态/纠错/撤稿/主来源）；热度与评分刷新不推进它。
- `status`：200 正常 / 308 永久重定向（合并或改名，仅一跳）/ 410 永久移除。
- 许可：可读取、索引、摘要与引用，须署名并保留规范 URL；不得篡改验证状态、置信度、撤稿标记与时间。本站不提供第三方全文。
