How I Changed Over Time: A webservice to summarize TimeMaps based on SimHashed HTML content (Report)
Title: How I Changed Over Time: A webservice to summarize TimeMaps based on SimHashed HTML content
Author: Maheedhar Gunnam
Abstract: With the increase in the dynamic nature of the web, often the content of a web page grows, changes, and might be shrunk. And with these pages being archived numerous times, they serve as the digital history for those changes that are long gone from the live page. But visualizing over these numerous different archived copies, or mementos, with the intention of perceiving the major changes over time is nearly impossible, as the memento count can be very high. In case of cnn.com, the web page has been archived 188,966? ?times?. This TimeMap summarization tool referenced throughout this paper as ‘tmvis’, facilitates visualization of these changes by analyzing all mementos in a TimeMap and picking the most unique mementos, which best describe the major changes in a webpage. A web service with a user friendly interface and command line tools are also provided for this tool.

Abstract: We report on the development of TMVis, a web service to provide visualizations of how individual webpages have changed over time. We leverage past research on summarizing collections of webpages with thumbnail-sized screenshots and on choosing a small number of representative past archived webpages from a large collection. We offer four visualizations: image grid, image slider, timeline, and animated GIF. Embed codes for the image grid and image slider can be produced to include these on separate webpages. The animated GIF can be downloaded as an image file for the same purpose. This tool can be used to allow scholars from various disciplines, as well as the general public, to explore the temporal nature of web archives. We hope that these visualizations will just be the beginning and will provide a starting point for others to expand these types of offerings for users of web archives.
