Al Cornish and Jon Scott (WSU) on LCSH Autocomplete in WorldCat.org:
- Autocomplete = program predicts word/phrase that user wants. Ubiquitous.
- Subject autocompletion in WC based on LCSHeadings
- When terms appear in the a-c drop-down they’re ordered not alphabetically but by “fitness” (approx. count of # of records returned in WC.)
- Also available for MeSH and other subject headings systems
- Test here.
- Can type a % in that test window to see the macro subject areas listed in order of fitness. “History” is #1.
- Populates database using LCSH preferred headings from online list provided by LCSH.
I love this–amazing how much it helps focus and direct users’ searches toward correct LCSH, and helps clear up confusion about what a “subject” is (or, actually, removes the whole fiddly conversation about why subject headings matter) while still using LCSH to structure data, and getting people to the right item records.
