OCLC Online Computer Library Center DeweyBrowser  The DeweyBrowser is a research prototype that supports searching and browsing collections of resources organized by Dewey  The prototype was developed to make the most of DDC numbers assigned to library materials and to explore the use of AJAX (Asynchronous JavaScript and XML)

OCLC Research OCLC Online Computer Library Center DeweyBrowser  The interface presents search results at three levels, i.e., the three main summaries of Dewey  To use the prototype, a user navigates up and down the Dewey hierarchy by clicking on a category or enters a search term  The categories are color-coded to indicate where matching records occur  red, orange, and yellow (warm colors) — many records  green and blue (cool colors) — fewer records  white — no matching records

OCLC Research OCLC Online Computer Library Center DeweyBrowser  Summaries can be displayed in English, French, German, Spanish, or Swedish  Search and browse results can also be limited to resources written in a particular language

OCLC Research OCLC Online Computer Library Center DeweyBrowser  The DeweyBrowser has been deployed over three collections of resources:  ebooks - 210,000+ electronic books ebooks  wcat – 2.2 million of the most widely held WorldCat records wcat  abr14 – selected data from the Abridged Edition 14 of DDC abr14  WorldCat and ebooks collections are linked to the Find in a Library Web service

OCLC Research OCLC Online Computer Library Center Dewey Browser  The Abridged 14 collection includes a collaborative editing feature that enables authorized users to suggest index terms for a DDC class (Suggested terms)  Suggested terms will be delivered to interested users via RSS

OCLC Research OCLC Online Computer Library Center DeweyBrowser & AJAX  AJAX is an approach to programming web interfaces that allows user interaction with a web page without refreshing the whole screen  Using AJAX speeds up the interface by only requesting parts of a page  Refreshing only the part of the screen that changes tends to encourage exploration, behavior that is central to how the DeweyBrowser was designed to be used  The DeweyBrowser is an example of an entire application built using AJAX

OCLC Research OCLC Online Computer Library Center Curiouser  Curiouser is an approach to making the best use of data about items in WorldCat and a user interface for exploring and selecting works and items  The prototype interface  employs the OCLC FRBR work-set algorithm  exploits structured data in bibliographic, authority, and holdings records,  integrates techniques from FictionFinder for display and navigation of records in a FRBR context,  explores Web services and other data sources to enhance the utility of Open WorldCat

OCLC Research OCLC Online Computer Library Center OCLC FRBR Work-Set Algorithm  A work set is a group of bibliographic records with the same Author/Title key  A key is generated for each bibliographic record  Variant forms of names and titles are converted to established forms based on the OCLC authority file  Keys are sorted and compared to form work sets
