I would like to inquire about the labeling issues in the meta-dataset

Hello, I would like to ask about the meta-dataset. In the context of COVID-19, the RT_PCR_positive field contains two values: Y and unclear. I would like to confirm if unclear is considered negative, correct?

You can consider unclear the same as being blank. An N value will be there if it is considered negative.

The schema is here (although it doesn't mention 'unclear'): https://github.com/ieee8023/covid-chestxray-dataset/blob/master/SCHEMA.md

Thank you for your response. I would like to confirm if it is possible to filter the COVID-19 data using the "finding" column in the meta.csv file?

I'm not sure what you mean. Filter how?
