  1. PubMed Searching: Automatic Term Mapping (ATM) PubMed for Trainers, Spring 2014U.S. National Library of Medicine (NLM) and NLM Training Center

  2. Objectives • By the end of this session, you should be able to: • Describe how PubMed processes a search using Automatic Term Mapping (ATM) • Use Search Details to determine how PubMed processed your search • Modify your PubMed search based on what you learn from Search details PubMed for Trainers

  3. Composing Your Search • Be specific • Use no punctuation (e.g., no quotation marks) • Use no operators (e.g., AND) • Use no tags • Capitalization is unimportant PubMed for Trainers

  4. ATM in Action

  5. ATM (continued) PubMed looks for: • Subjects • Journals • Authors In that order. PubMed for Trainers

  6. MeSH (Subject) Translation Table Contains: • MeSH Headings • Subheadings • Publication Types • Entry Term mappings (also known as synonyms) for MeSH terms • Supplementary Concepts and synonyms to the Supplementary Concepts • Mappings derived from the Unified Medical Language System (UMLS) PubMed for Trainers

  7. When a Match is Found for your Subject Processing now stops! PubMed for Trainers

  8. Automatic Explosion: What you Don’t See in Search Details PubMed for Trainers

  9. PubMed for Trainers

  10. Pop Quiz! PubMed for Trainers

  11. ATM (cont’d) If PubMed doesn’t find a match in the MeSH subject table, it looks for: • Subjects • Journals • Authors PubMed for Trainers

  12. Journals Translation Table • Full journal title • MEDLINE abbreviation • International Standard Serial Number (ISSN) PubMed for Trainers

  13. When a Match is Found for your Journal Title Processing now stops! PubMed for Trainers

  14. Pop Quiz! PubMed for Trainers

  15. ATM (cont’d) If PubMed doesn’t find a match in the journals table, it looks for: • Subjects • Journals • Authors PubMed for Trainers

  16. Author Translation Tables • Author Index • In the format: Lastname Initials: • Jennings BH • Full Author Translation Table • Author names in natural and inverted order: • Barbara H Jennings • Jennings, Barbara H • Investigator Index • Full Investigator Translation Table PubMed for Trainers

  17. When a Match is Found for an Author Name Processing now stops! PubMed for Trainers

  18. Pop Quiz! PubMed for Trainers

  19. ATM: Searching Multiple Concepts PubMed for Trainers

  20. Combining Subjects, Journals & Authors: What does ATM Do? PubMed for Trainers

  21. No match in any of the translation tables? PubMed for Trainers

  22. Phrase Searching with Quotes Caution! Using quotes bypasses ATM & automatic explosion. PubMed for Trainers

  23. Quoted Phrase Not Found PubMed for Trainers

  24. Exercise Search the following in PubMed: • “health planning” • health planning What is missed in the first search? PubMed for Trainers

  25. Searches that Bypass Automatic Term Mapping: • Using a search tag: • Gene [author] • Science [journal] • Forcing a phrase search with quotes: • “pressure point” • Using the Single Citation Matcher • Using Advanced Search Use with caution! PubMed for Trainers

  26. Summary • For most PubMed searches justenter your terms and click Search. • Always check Search details • Automatic Term Mapping processes subjects, journals and authors, in that order. PubMed for Trainers

  27. Summary • With ATM, your MeSH terms will automatically explode to include narrower topics. • The 3 ways to enter journal titles are: • Full journal title • MEDLINE journal title abbreviation • ISSN • For the most comprehensive author search, use the format lastname initials (e.g., smith ja). • If necessary, bypass ATMby using: • Quotations or tags • Single Citation Matcher • Advanced Search (to be discussed later) PubMed for Trainers

  28. You should now be able to: • Describe how PubMed processes a search using Automatic Term Mapping • Use Search Details to determine how PubMed processed your search • Modify your PubMed Search depending on what you learn from Search Details PubMed for Trainers
