RSLFW at the NTCIR-18 FairWeb-2 Task

Key Points

To evaluate different retrieval methods in the NTCIR-18 FairWeb-2 task.
Implemented BM25, ColBERT, and PM-2 algorithms
Generated five submission runs
Conducted analysis comparing with official baseline and FairWeb-1 runs
Achieved varying performance levels across the different retrieval methods
Comparison highlighted strengths and weaknesses of each algorithm
Results provide insights for future retrieval challenges

Abstract

This report presents the participation of RSLFW team at the NTCIR-18 FairWeb-2 task.We implemented several different retrieval methods to generate five runs using BM25, ColBERT and PM-2 algorithm.In addition to the runs submitted, the results are analyzed through comparison with the official baseline and FairWeb-1 reproduction (revived) runs.
