DeweyBrowser & Curiouser

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)


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


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


DeweyBrowser

The DeweyBrowser has been deployed over three collections of resources:

ebooks - 210,000+ electronic books

wcat – 2.2 million of the most widely held WorldCat records

abr14 – selected data from the Abridged Edition 14 of DDC

WorldCat and ebooks collections are linked to the Find in a Library Web service


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


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


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 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
