Distributed Index for Near Duplicate Detection

ZHANG Yue,YU Haomin,ZHANG Qi,HUANG Xuanjing(Fudan University,School of Computer Science and Technology,Shanghai 201203,China)  
How to effectively detect near duplicate documents on large corpus is a hot topic in recent years.Usually,near duplicate detection algorithms use Inverted Index to improve their efficiency.However,as the corpus size increases,single machine implementation of index structure is intractable.Therefore Distributed Index structure is required for near duplicate detection.To process rapidly increasing data size,the distributed index structures should have both high efficiency and scalability.In this paper,we compare two different distributed index structures,Term-Split Index and Doc-Split Index,and provide the Map-Reduce implementation.Based on those two index structures,we propose two different approaches,Term-Split Approach and Doc-Split Approach,to detect near duplicate documents using Map-Reduce paradigm.Finally,we compare the performance of the two different approaches on WT10G corpus.Experimental results show that the Doc-Split Approach is more efficient and has better scalability.
