Abstract:

 This  paper  proposes  a  new  autonomous  self-organizin g  content-based  node  clustering  peer  to  peer  Information 
Retrieval  (P2PIR)  model.  This  model  uses  incrementa l  transitive  document-to-document  similarity  technique  to  build  Local 
Equivalence  Classes  (LECes)  of  documents  on  a  sourc e  node.  Locality  Sensitive  Hashing  (LSH)  scheme  is applied  to  map  a 
representative  of  each  LEC  into  a  set  of  keys  which   will  be  published  to  hosting  node(s).  Similar  LECes  on  different  nodes 
form  Universal  Equivalence  Classes  (UECes),  which  i ndicate  the  connectivity  between  these  nodes.  The  same  LSH  scheme  is 
used  to  submit  queries  to  subset  of  nodes  that  most   likely  have  relevant  information.  The  proposed  mod el  has  been 
implemented
.  The  obtained  results  indicate  efficiency  in  buildi ng  connectivity  between  similar  nodes,  and  correctl y  allocate 
and retrieve relevant answers to high percentage of  queries. The system was tested for different network sizes and proved to be 
scalable as efficiency downgraded gracefully as the  network size grows exponentially.
