数据标注

# 先让大家理解同一个标签，再扩大数据量。

如果不同审核人员对标签含义理解不同，增加标签数量并不能解决问题。我们围绕模型任务组织标注，写出可执行的规则，在扩大规模前检查一致性，并连同定义和质量记录一起交付数据。

合作范围

## 数量扩大之前，先对含义达成一致。

1. **定义标签** 明确任务、类别、边界情况和允许用途。
2. **校准审核** 通过共同样本、分歧讨论和明确规则建立一致性。
3. **带证据交付** 提供版本化导出、质量检查和排除记录。

直接说明

数据标注为模型训练和评估创建经过复核的标签。合作包括标签定义、校准样本、标注流程、质量检查，以及带版本记录和已知限制的数据集。

适合以下需求

- 为明确模型任务准备文本、图像、音频或视频样本的团队
- 已有标签不一致，或缺少复核证据的数据负责人

其他需求路径

- 一般数据仓库或业务报表管道建设
- 尚未明确用途和使用权限的数据收集

## 让标签服务于后续任务

我们明确每个标签的含义、适用条件和应保留不确定性的情况。文本分类器可能需要文档级类别；视觉模型可能需要框、区域或整图标签。标注粒度必须匹配模型及其支持的业务决策。 [机器学习](/zh/services/machine-learning/) 或 [计算机视觉](/zh/services/computer-vision/) 可以先帮助确定该目标。

## 在小样本阶段解决分歧

审核人员按照相同说明标注约定样本。我们检查差异、完善定义并记录裁定，再增加处理量。罕见和多义情况使用具体例子说明。领域判断由合适的专业负责人承担；标注说明不能替代任务真正需要的专业知识。

## 明确选择工具和复核方式

流程可以采用模型建议、人工标注，或两者结合。模型建议保留其来源标识，按照约定政策审核。访问、存储、脱敏和导出格式在工作开始前确定。我们针对实际数据集确认语言和专业覆盖，不默认同一种人员配置适用于所有资料。

## 示例验收：支持请求的类别存在重叠

一个示例数据集中，同一条消息同时提到延迟送货和退款请求。审核人员最初分别选择不同的单一标签。团队决定采用多标签规则，修改说明并重新检查受影响记录。交付数据注明规则版本和质量样本，让后续模型评估使用正确的类别含义。

## 保留数据集的演变过程

成果包括标签结构、说明、数据集版本、复核结果，以及被排除或仍有争议的案例。训练和评估分区按照约定抽样设计保持分离。修正记录单独版本化；个人数据或有许可要求的素材遵守约定保留政策。LLM 评估数据集可通过 [AI 评估与 LLMOps](/zh/services/ai-evaluation-llmops/) 继续维护。

## 开始前的常见问题

### 提供自动标注还是人工标注？

查看任务与样本后选择合适组合。自动建议可以帮助提速，但验收政策会明确哪些内容必须审核，以及怎样衡量质量。

### 可以修复已经标注过的数据集吗？

可以。样本审查先识别含义模糊的类别、冲突标签和覆盖缺口。双方约定需要修正的记录，并保留旧版本用于比较。

### 专业性很强的内容由谁判断？

接受工作前明确所需领域审核人员及其可用性。你的团队也可以提供专业知识。我们不会把一般标注经验等同于领域资质。

### 有了标签就能保证模型好用吗？

不能。标签只解决模型质量的一部分。数据代表性、信息泄漏、模型方案和评估设计仍需要按照实际任务检查。
