Dynamically Growing Hypertext Collections

1. Dynamically Growing Hypertext Collections Pratik Dave, Paul Logasa Bogen II Unmil Karadkar Luis Francisco-Revilla, Richard Furuta, Frank Shipman

2. Abstract • Creating, Organizing and Sharing information from large information space. • Less attention to addition of new materials to the existing collection. • A prototype for automatically adding new materials. • Path browsing Metastructure - Layering metastructure atop existing hypertextual machines.

3. Introduction • “Keeping Found things Found” – need for locating and organizing findings. • Information Filtering • Deals with unstructured and semi-structured data. • Focus upon users long term or repeated interests. • Paths or trails – access to subset of information. • Maintaining Collections • User patterns of storing relations correlates to patterns of seeking information. • Interconnected path structure – maintains several layers of interrelationships between materials simultaneously.

4. Syndication of Web Content • Web syndication • Making web feeds available from a site with a summary of websites recently added content. • Feed – a data format to publish frequently updated content. • Linear paths arranged in chronological sequence • Imports the contents of feeds into path browsing system to create meta collections linking together web pages.

5. System – Walden Path • Walden paths • Suite of tools to create, present and maintain linear interconnected paths. • Paths provide metadata • Annotations • Human ordering • A structure atop of existing web pages. • Basic unit of information – stop (references to a webpage via a URL).

6. Walden path - Approach

7. Walden Path - Approach • Locating Materials – de and re-hypertextualization of given material • Web syndication creates a layer of sequential relationship atop the existing hypertext. • Pages in feeds (same or diff sites) possess linear chronological relationships. • System takes from multiple feeds and provides further linkages. • Creating additional structure on top.

8. Architecture • Creating paths from syndication feeds into walden path system. • Extracting key phrases. • Browsing Interface.

12. Benefits • Filtering – ease the task of seeking particular information • Enables users to save collection and ability to backtrack to previous information. • Spares mental effort of navigating complex web pages.
