The statements that are NOT correct about stemming and lemmatizing are:

1. "Stemming may also require more domain-specific knowledge or training data" - This is incorrect because stemming is a rule-based process of stripping the suffixes (“ing”, “ly”, “es”, “s” etc) from a word. It doesn't require domain-specific knowledge or training data.

2. "Stemming can preserve the semantic relationships between words" - This is also incorrect. Stemming does not preserve semantic relationships between words. It simply reduces words to their root form, which can often result in a word that is not semantically related to the original word. For example, the stem of the word "running" is "run", but the stem of "runner" is also "run", even though "running" and "runner" do not have the same semantic relationship.

The other statements are correct. Stemming can result in errors or inconsistencies because it is a crude process. It is a faster and simpler approach than lemmatizing, which involves understanding the context and part of speech. And finally, stemming can indeed reduce the dimensionality (vocabulary size) of text data by reducing words to their root form.
