3. Issues for Exploiting Resources • Understand the information need • Identify appropriate resource • Translation of context data for querying • Interaction with the resource

4. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

5. Match concept of interest to class(es) • Identify context based on class(es) • Retrieve question(s) for context • Sort by “priority” • Return HTML page of links (URLs)

6. Interactions With On-line Resources • Question has “hardcoded” URL • e.g.: “www.columbia.edu/potassium.pdf” • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

7. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

9. Interactions With On-line Resources • Translate concept of interest to controlled term • Find controlled term in data dictionary • Obtain term attribute for constructing URL from data dictionary • Construct URL, e.g.: • www.columbia.edu/lab/<>.html • + cl001900 . • www.columbia.edu/lab/cl001900.html • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

10. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

12. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator Insert concept of interest into CGI function call as a parameter e.g.: www.Uptodate.com/search.cgi?term=<> + POTASSIUM . www.Uptodate.com/search.cgi?term=POTASSIUM

13. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

15. Interactions With On-line Resources • Translate concept of interest to controlled term • Obtain term translation from data dictionary • Insert translated term into CGI function call as a parameter • e.g.: • pubmed.gov/search.cgi?term=<>[MeSH+Terms] • + Potassium . • pubmed.gov/search.cgi?term=Potassium[MeSH+ Terms] • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

16. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

18. Interactions With On-line Resources • Resource is not a simple document or search CGI • Log-on, navigation or other interaction required • Multiple context parameters used • Agent: • parses context parameters • interacts with resource • parses results • presents summary • may modify links • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

19. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

21. Interactions With On-line Resources • No resource available • Interaction too complex • Create self-contained agent: • parses context parameters • constructs Web page • presents results • may have Infobuttons of its own • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

22. Interactions With On-line Resources • Simple link • Concept-based link • Simple search • Concept-based search • Intelligent agent • Calculator

24. Discussion • Resources are available • Simple interactions are usually possible • Interaction method (format) issues: • “Give me a page” vs. “Give me the answer” • Standards needed for asking questions • Standards needed for passing parameters • Representation (terminology) issues: • Clinical systems use homegrown “standards” • Resources (except PubMed) don’t use any standards (i.e., they are indexed by text word)

25. Conclusions • Resources exist • Creative solutions required • Engaging resource providers is next step
