  • Redirection spam presents a web page with false content to a crawler for indexing, but automatically redirects the browser to a different web page. Redirection is usually immediate (on page load) but may also be triggered by a timer or a harmless user event such as a mouse move. JavaScript redirection is the most notorious of redirection techniques and is hard to detect as many of the prevalent crawlers are script-agnostic. In this paper, we study common JavaScript redirection spam techniques on the web. Our findings indicate that obfuscation techniques are very prevalent among JavaScript redirection spam pages. These obfuscation techniques limit the effectiveness of static analysis and static feature based systems. Based on our findings, we recommend a robust counter measure using a light weight JavaScript parser and engine.

paul perry - Web Annotations

    • Annotations are a broadly useful mechanism that can support a number
      of document and database management applications:
      • provide a trace of use
      • third party commentary
      • information sharing
      • information filtering
      • semantic labeling of document content
      • enhanced search


      But it continues to be hard to publish to the web. If better tools
      are provided to information consumers then readers will be able to add
      commentary, make new connections, interpret content, and otherwise
      promote an accretion of both structure and content on the web. This
      process will add new semantics to the web and this new information
      will be the source for new approaches to searching and filtering of
      information.

  • t sheet, rendering strips that could
    even be several meters long and that came to be rolled up in volumes. To
    improve the possibility of using this surface for writing, Egyptians beat,
    scraped, and smoothed papyri during their production. Egyptian scribes wrote on
    papyrus using brushes and ink.

  • Shortly after the Sumerians, ancient Egyptians developed their own writing. They
    took some of their symbols from the Sumerians, but also invented many other
    symbols, comprising an original script of their own. Egyptian writing was
    prevalently used for sacred and celebratory purposes; for this it came to be
    called hieroglyphic (‘sacred writing’). Egyptians sculpted or painted their
    writings on stony temple walls and wooden sarcophagi.
