October Meeting • DeweyBrowser—searching and browsing by Dewey; interface programmed in AJAX (Asynchronous JavaScript and XML) • Curiouser—employs OCLC FRBR work-set algorithm to group related records
Agenda • Classify—Uses FRBR groups toenrich records with Dewey numbers • LiveSearch—New search interface which employs Dewey and Ajax techniques
Classify • OCLC Research Team • Diane Vizine-Goetz • Harry Wagner • Features • Employs data mining of holdings and FRBR • Human- and machine-readable interfaces that resolve OCLC record number or ISBN to DDC or LCC
Phoenix Public Library • 222,197 without DDC numbers • 44,704 DDC added from FRBR-clustered records • Four DDC main classes accounted for more than 91% class numbers
Experimental Classification Service • Demo • Elfquest (frbr group) • Frugal housewife • Say it in Polish • Senate ethics manual
Next steps • Apply to nearly 1 million WorldCat records without Dewey numbers excluded from DeweyBrowser • Conduct a feasibility study of current cataloging records from British Library without DDC
Live Search • OCLC Research Team • Thom Hickey (lead) • Jenny Toves • Ralph LeVan • Features • Quick searches target with each additional keystroke of search term/phrase • Retrieves ordered, FRBR-grouped results • Uses Dewey to narrow search results • Demo • Phoenix Public+DDC [former--Phoenix w/o DDC]
