We seek detail-oriented human annotators to label technical documents about engineered metallic materials, including patents, standards, datasheets, and research literature.
Job Scope
- Label entities such as material identities, composition specifications, material states, and sources.
- Record composition constituents, amounts, and units exactly as written.
- Capture stated links such as material-to-composition, material-to-state, claim/example relationships, and coreference.
- Preserve span IDs and verbatim text needed for later resolution.
- Leave external classification, normalization, equivalence mapping, unit defaulting, and material-family decisions to a separate expert resolution process.
- Nice to have/stretch: help develop or evaluate LLM-assisted annotation workflows that improve productivity while preserving human review quality.
The role requires accuracy, consistency, and restraint
Requirements：
- Strong reading comprehension for technical English and/or Chinese.
- Familiarity with materials science, metallurgy, chemistry, patents, or technical documentation.
- Ability to preserve exact spans, wording, units, ranges, and symbols.
- Attention to document context, especially references such as "said alloy," "Example 2," or "the composition."
- Comfort following structured annotation guidelines and recording labels consistently.
- Good judgment about when information is explicitly stated versus inferred from outside knowledge.
