Tagging Practices on Research Oriented Social Bookmarking Sites (Note: PDF)

From the Digital Library of Information Science and Technology, University of Arizona website

This paper examines the tagging practices evident on CiteULike, a research oriented social bookmarking site for journal articles. Tagging practices were examined using standard informetric measures for analysis of bibliographic information and term use. Additionally, tags were compared to author keywords and descriptors assigned to the same article.


PhotoSpread: A Spreadsheet for Managing Photos (Note: PDF)

From the Stanford InfoLab website

PhotoSpread is a spreadsheet system for organizing and analyzing photo collections. It extends the current spreadsheet paradigm in two ways: (a) PhotoSpread accommodates sets of objects (e.g., photos) annotated with tags (attribute-value pairs). Formulas can manipulate object sets and refer to tags. (b) Photos can be reorganized (tags and location changed) by drag-and-drop operations on the spreadsheet. The PhotoSpread design was driven by the needs of field biologists who have large collections of annotated photos. The paper describes the PhotoSpread functionality and the design choices made.

The PhotoSpread Query Language (Note: links to a PDF)

From the Stanford InfoLab website

This document defines the data model as well as the syntax and semantics of the formula language employed by PhotoSpread. It is inspired by Excel with specialized and enriched functionality for managing and tagging large photo collections in a spreadsheet. PhotoSpread allows for capturing, storing, arranging, manipulating, and querying arbitrary tagged photo objects with an intuitive and easy-to-learn, yet expressive formula language.
