Summary

databricks-dolly-15k-ja-scored is a version of databricks-dolly-15k-ja, which is a machine-translated version of databricks-dolly-15k, with added translation quality scores provided by BERTScore.

Translation Quality Score

When examining the data contained in databricks-dolly-15k-ja, I found the following data of poor quality.

  1. Data where input and output are exactly the same
  2. Data where output is copied to instruction
  3. Data in which the consistency of expression is not maintained due to notation.
  4. Data that has failed to translate proper nouns, etc.

Note that in databricks-dolly-15k

  • Data corresponding to 1. has been removed.
  • Data corresponding to 2. has its instruction removed and its category changed to open-qa.

Therefore, I back-translated these data from Japanese to English and examined the similarity with the original text by BertScore. Below is a histogram of f1 score, the harmonic mean of precision and recall.

You can filter out low-quality data by filtering with f1 score.

Notes

The derived score varies depending on the service used for Japanese-English translation and the model used in BertScore. Even with data that is OK to use for learning, the score may drop depending on the accuracy of the Japanese-English translation.

Description of each field

I will explain only the added parts and the items that need attention.

1. index

A unique identifier for the data. Originally a field indicating which lines of databricks-dolly-15k have been translated, but the index does not correspond to the actual line because databricks-dolly-15k-ja does not reflect a change in the element deletion of databricks-dolly-15k.

Field Description
Index The unique identifier for the data

2. bertscore

Evaluation score provided by the BERT model. It consists of three indices: recall, precision, and f1.

Field Description
recall A measure of how much information contained in a correct answer text is reflected in the generated text
precision A measure of how well each part of the generated text matches the correct text
f1 Harmonic mean of precision and recall.

3. translator

Information of the translation services used. There are two fields, "en_ja" and "ja_en", which represent the services used to translate English to Japanese and Japanese to English, respectively.

Field Description
en_ja Service used to translate from English to Japanese
ja_en Service used to translate from Japanese to English
