Create a test set

To create or add to an NLU test set, you can upload a file of test utterances matched with correct intents. Use the test set to assess the performance of your model.

始める前に

• Ensure that the NLU Workbench - Core plugin, NLU Workbench plugin, NLU Workbench - Advanced Features plugin and Predictive Intelligence plugin are all installed and activated
• You can use test sets with NLU models for Virtual Agent and AI Search.
• Role required: nlu_editor, nlu_admin, or admin. The editor must be assigned to the model.

このタスクについて

Your CSV or XLSX (Excel Workbook) file should contain a table that pairs your test utterances with the intents that you expect for them. Your file can contain up to 10,000 utterances. Ensure that the file has columns titled "Utterance" and "Expected intent".

注:

For test sets in languages other than English, you must add the glide.import.csv.charset system property with the value UTF-8. See Import sets properties.

For the most accurate test results, include utterances that the model is likely to encounter from your users. Ensure that you have test utterances covering all the intents in your model.

Aim to include about 10% of test utterances with no expected intents. Including utterances with no expected intent helps assess your model's ability to detect irrelevant utterances that should not have any intent predicted.

注:

To indicate that a test utterance in your file has no expected intent, the value for "Expected intent" should be empty.
