  1. ALGORITHM TO FIND HIDDEN LINKS IN A WEB PAGE Under the guidance of Mr. Indraneel Mukhopadhyay Presented by Pradyut Kumar Mallick Roll # IT200127292

  2. 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. Introduction

  3. A cyclic hyperbolic space with hidden links

  4. 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. A cyclic hyperbolic space with hidden links

  5. 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 . New Technique

  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. Definitions

  7. Definition of Cyclic Hierarchical Space

  8. Primary Path: (tree-link) “AE” Secondary Path (non-tree/cross link) “AB Hidden-Link Node Primary Sub-Space Nodes Secondary Sub-Space Nodes Placeholder Definition of Cyclic Hierarchical Space

  9. State 1: Idle State State 2: Activate State Hidden Link States and Processing Flow

  10. State 3: Map/Unmap (move) State State 4: Navigation State Hidden Link States and Processing Flow

  11. State 5: Reset Hidden Link States and Processing Flow

  12. “Hidden Link” Client-Server Web Structure

  13. Code • The basic link tag looks something like <a href="hidden.html">click here</a>. • <a href="hidden.html" style="cursor:help"> • <a href="hidden.html" style="color:#FF0080"> • <a href="hidden.html" style="text-decoration:none"> 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: Algorithm

  15. Website & Search Pattern of Hidden Links

  16. CONTENT AND USAGE MINING CUSTOMER INTERVIEW WEB SERVICE Hidden Link Applications

  17. <div id="Links0" style="LEFT:0px;TOP:0px; VISIBILITY:hidden; POSITION: absolute;"><a href="index1.htm">hasdf hdkfh afhkj </a><a href="index2.htm">kjhf haksf hkasf </a><a href="index3.htm">kjhkjdf khdkf haf</a><a href="index4.htm">ghdf gdjf kgdf</a> 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.
