Sure! Examples include incomplete datasets, noisy data with irrelevant information, and biased samples that don't represent the target population.

How can we improve data quality for NLP tasks?

Improving data quality can involve data cleaning, using diverse datasets, and implementing robust validation techniques to ensure accuracy.

What tools can help in assessing data quality?

There are several tools like OpenRefine for data cleaning, and libraries like Pandas in Python for data manipulation and quality checks.

Is there a specific metric to measure data quality?

Yes, metrics like completeness, consistency, accuracy, and timeliness are commonly used to assess data quality in NLP.
