Knowledge Check
Exercises
Now it’s time to see what you learned! You can retake the knowledge check as many times as you want, and then move on to the next section.
When you search for a phrase in PubMed, without any punctuation or tags (for example: colon cancer), what does PubMed’s Automatic Term Mapping (ATM) feature do?
Answer
a) PubMed’s Automatic Term Mapping (ATM) feature attempts to map the phrase to a MeSH term and breaks the phrase apart to process each term individually.
If you search for a phrase in PubMed without any punctuation or tags (for example: airbag injury), and your phrase does not map to a MeSH term, what does PubMed do next?
Answer
b) PubMed bypasses ATM and breaks the phrase apart to process each term individually.
