ILLUSTRATIVE EVALUATION / 日本語
AI RESPONSE / 3 CLAIMS
光合成について
植物は光エネルギーを利用し、二酸化炭素と水から有機物を合成する。
01 / PASS — Core claim supported
放出される酸素は、二酸化炭素に由来する。
02 / MAJOR ISSUE — Oxygen derives from water
光合成の効率は、光の強さや温度などに左右される。
03 / PASS — Acceptable Simplification
02 / EXPERT REVIEW
1 substantive correction; 1 terminology issue
EXPERT EVALUATION SUMMARY
Factuality / Major issue in claim 02
Reasoning / Mechanistic explanation needs revision
Japanese Quality / Clear and natural
Scientific Terminology / “photosynthetic efficiency” is not clearly defined.
02 / WHY THIS MATTERS
Why This Matters
A response can sound natural — and still be scientifically wrong.
Fluent Japanese is not enough.
Evaluating scientific AI output requires a combination of domain expertise, native-language judgment, and professional science communication.
Human expert review provides a critical reference for identifying factual errors, flawed reasoning, misleading certainty, terminology problems, and domain-specific failure modes in Japanese-language outputs.
Scientific Expertise
Rigorous evaluation grounded in scientific knowledge and research experience.
Scientific Communication
Clear, accurate judgment of how complex scientific concepts are communicated to the intended audience.
Japanese Language Precision
Native-level evaluation of terminology, nuance, clarity, precision, and naturalness.
03 / WHAT WE EVALUATE
What We Evaluate
Structured Expert Evaluation for Scientific AI
01
Factual Accuracy
Are scientific claims accurate and appropriately qualified?
02
Reasoning Quality
Does the conclusion follow from the evidence and underlying science?
03
Hallucinations & Unsupported Claims
Does the output invent facts, sources, mechanisms, relationships, or unwarranted certainty?
04
Japanese Language Quality
Is the Japanese clear, natural, precise, and appropriate for the intended audience?
05
Scientific Terminology
Are scientific and technical terms used accurately and consistently?
06
Claim-Level Evaluation
Individual scientific claims are assessed separately.
Standard Deliverables
Structured evaluation labels, expert comments, a project-specific error taxonomy, and a summary report highlighting recurring failure patterns and areas of concern.
Delivery formats can include CSV, JSONL, or client-defined formats.
Reviewer comments and summary reports are delivered in English by default, with Japanese available on request.
04 / OPTIONAL ADD-ONS
Optional Add-ons
All of the following are available as paid add-ons.
01
Expert Correction & Rewriting
Receive corrected or rewritten Japanese responses for outputs containing scientific or linguistic issues.
02
Extended Literature Verification
Conduct broader literature review when targeted source checking is not sufficient.
03
Citation Verification
Verify cited papers, sources, attribution, and whether references actually support the model's claims.
04
Additional Domain-Expert Review
Add a second or additional specialist review for high-stakes or highly technical content.
05 / EVALUATION EXAMPLES
Evaluation Examples
Representative examples
The examples below illustrate our evaluation approach and are not taken from client projects or a specific AI model.
Prompt
地球温暖化によってサンゴの白化が起こる仕組みを説明してください。
Model Response
海水温が上昇すると、サンゴは体内の褐虫藻を放出します。白化したサンゴはすぐに死亡し、水温が通常より1℃高くなると白化が起こります。
海水温が上昇すると、サンゴは体内の褐虫藻を放出します。
01 / PASS — Acceptable Simplification
Thermal stress can cause corals to lose their symbiotic algae or their pigments, resulting in bleaching. “Release” is broadly understandable but somewhat oversimplified.
白化したサンゴはすぐに死亡し、
02 / MAJOR ISSUE
Coral bleaching does not necessarily result in immediate mortality. Bleached corals can survive and recover if stressful conditions subside.
水温が通常より1℃高くなると白化が起こります。
03 / MAJOR ISSUE
Bleaching risk depends on both the magnitude and duration of thermal stress. A simple 1°C threshold does not mean bleaching will necessarily occur.
Overall Factuality: Major Issues
Error Types: Oversimplification · Overgeneralization · Overstated certainty
Japanese Quality: Pass

08 / HOW A PILOT WORKS
How a Pilot Works
Start Small. Evaluate Real Model Outputs.
01
Scope & Calibration
Define the project scope and review an initial sample to align the evaluation rubric, severity levels, terminology, and error taxonomy.
02
Evaluation
Native Japanese scientific experts evaluate model outputs using the agreed framework, with structured internal quality control.
03
Delivery
Receive structured evaluation data, expert comments, source-verification results where applicable, and a project summary highlighting recurring failure patterns.
Typical Pilot
Up to 100 responses · Approximately 2 weeks
Start with a focused pilot, then scale based on your evaluation needs.
09 / FAQ
FAQ
Do you only evaluate biology?
No. Biology, environmental science, and biomedical sciences are our core domains, but we can support other scientific and technical fields depending on the project.
Contact us to discuss your specific domain requirements.
Can you work with confidential model outputs under NDA?
Yes. We can work under your organization’s NDA and confidentiality requirements.
Can you provide corrected Japanese responses?
Yes. Expert correction and rewriting of problematic Japanese responses is available as a paid add-on.
Can you verify scientific sources and citations?
Yes. Targeted source verification can be included depending on project scope. Extended literature and citation verification are available as paid add-ons.
