DeweyBrowser </p> <ul><li>The DeweyBrowser is a research prototype that supports searching and browsing collections of resources organized by Dewey </li></ul> <ul><li>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) </li></ul> <p> 3. DeweyBrowser </p> <ul><li>The interface presents search results at three levels, i.e., the three main summaries of Dewey </li></ul> <ul><li>To use the prototype, a user navigates up and down the Dewey hierarchy by clicking on a category or enters a search term </li></ul> <ul><li>The categories are color-coded to indicate where matching records occur </li></ul> <ul><li><ul><li>red, orange, and yellow (warm colors) many records </li></ul></li></ul> <ul><li><ul><li>green and blue (cool colors) fewer records </li></ul></li></ul> <ul><li><ul><li>white no matching records </li></ul></li></ul> <p> 4.

DeweyBrowser &amp; AJAX </p> <ul><li>AJAX is an approach to programming web interfaces that allows user interaction with a web page without refreshing the whole screen </li></ul> <ul><li>Using AJAX speeds up the interface by only requesting parts of a page</li></ul> <ul><li>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 </li></ul> <ul><li>The DeweyBrowser is an example of an entire application built using AJAX </li></ul> <p> 8. 9. Curiouser</p> <ul><li>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 </li></ul> <ul><li>The prototype interface </li></ul> <ul><li><ul><li>employs the OCLC FRBR work-set algorithm </li></ul></li></ul> <ul><li><ul><li>exploits structured data in bibliographic, authority, and holdings records, </li></ul></li></ul> <ul><li><ul><li>integrates techniques from FictionFinder for display and navigation of records in a FRBR context, </li></ul></li></ul> <ul><li><ul><li>explores Web services and other data sources to enhance the utility of Open WorldCat </li></ul></li></ul> <p> 10.
