Use に基づいて to identify the facts, rules or information on which an action or judgment rests. It is common in formal writing.
The idea
Attach に基づいて to a noun, then state the action or result. に基づき is a more formal connective; に基づく directly modifies a following noun, as in データに基づく報告書.
| Form | Use |
|---|---|
| 結果に基づいて | 計画を作る |
| 結果に基づき | 計画を作る |
| 結果に基づく | 計画 |
Examples
- 調査結果に基づいて、計画を作りました。We made the plan based on the survey results.
- 医師は検査結果に基づいて、治療を選びました。The doctor chose a treatment based on the test results.
- その映画は実話に基づいて作られました。The film was made based on a true story.
- 住民の意見に基づき、規則が改められました。The rules were revised based on residents’ opinions.
- これは信頼できるデータに基づく報告書です。This is a report based on reliable data.
- その決定は法律に基づいて行われました。The decision was made based on the law.

Watch out
The noun is the basis used to make or do something, not merely the source of a report. によると introduces what a source says; に基づいて describes what a decision or action rests on.
