  • 1. ALGORITHM TO FIND HIDDEN LINKS IN A WEB PAGE
  • 2. INTRODUCTION
    • Hidden links are ones that real people aren’t supposed to actually notice or click on
    • Hidden links is a way to guide a search engine to our doorway pages.
    • New dynamic “hidden link” technique for linking a large highly connected graph in a simple hyperbolic space without cluttering the display.

  • 3. A CYCLIC HYPERBOLIC SPACE WITH HIDDEN LINKS [ ]
  • 4. A CYCLIC HYPERBOLIC SPACE WITH HIDDEN LINKS
    • In a hyperbolic space, the far away nodes/edges (paths) are diminished when the user is not focusing on them.
    • The user can dynamically warp the display to focus on thousands of different nodes for navigation .
    • This graph is a non-cyclic hierarchical hyperbolic structure without multiple connected paths.
    [ ]
  • 5. NEW TECHNIQUE
    • The user can easily navigate through all possible paths without tracing many lines and intersections
    • Robot programs called spiders create search engine databases, computer robot programs that crawl the web seeking search engine content
    • Pages created as the result of a search are called "dynamically generated" pages .
    [ ]
  • 6.
    • In a directed non-cyclic hierarchical space, there is a primary graph, which links all the nodes in a tree form. These links are primary tree links. The others are non-tree/cross links in a highly connected graph. A node can have one incoming primary link and many non-tree/cross links .

  • 8. DEFINITION OF CYCLIC HIERARCHICAL SPACE
    • Primary Path: (tree-link) “ AE ”
    • Secondary Path (non-tree/cross link) “ AB
    • Hidden-Link Node
    • Primary Sub-Space Nodes
    • Secondary Sub-Space Nodes
    • Placeholder

    • State 1: Idle State
    • State 2: Activate State

  • 10. HIDDEN LINK STATES AND PROCESSING FLOW
    • State 3: Map/Unmap (move) State
    • State 4: Navigation State

    • State 5: Reset

  • 12. “ HIDDEN LINK ” CLIENT-SERVER WEB STRUCTURE [ ]
  • 13. CODE
    • The basic link tag looks something like <a href=&quot;hidden.html&quot;>click here</a>.
    • <a href=&quot;hidden.html&quot; style=&quot;cursor:help&quot;>
    • <a href=&quot;hidden.html&quot; style=&quot;color:#FF0080&quot;>
    • <a href=&quot;hidden.html&quot; style=&quot;text-decoration:none&quot;>
    [ ] Cursor Type ………… . auto …………… crosshair …………… hand
  • 14.
    • Build hash table of links in the website.
    • Partition web log by visitor
    • For each visitor, partition web log file such that each subsequence terminates in a target page.
    • For each visitor and target page, find any expected locations for that page:

    [ ] Related Work
  • 18. [ ] Conclusion
    • The hidden link technique enables the mining of large hierarchies with multiple secondary paths
    • Hidden link enables the user to easily navigate through different links without being overwhelmed with large member of nodes and paths.
