Analyzing the Load Balance of Term-based Partitioning

Author 1: Ahmad Abusukhon Author 2: Mohammad Talib

In parallel (IR) systems, where a large-scale collection is indexed and searched, the query response time is limited by the time of the slowest node in the system. Thus distributing the load equally across the nodes is very important issue. Mainly there are two methods for collection indexing, namely document-based… Read full abstract & cite →
