External Ranking Function

This module provides utilities that allow to use external ranking function for Lucene and to evaluate its performance for TREC. In this case, I used Fuzzy Logic Ranking Function, but any other function could be used instead.

Procedure

Training Set Creation

In certain cases you need to create a training set for your function. I used various approaches to creation of Ranking Function, one of them was Adaptive Neuro Fuzzy Inference System (ANFIS) which required training data.

com.hrst.trec.FileConverter (creates training set)

com.hrstc.trec.ColumnExtractor (extracts data necessary for input to Ranking Function; in my case it was tf, idf, coord, boost)

com.hrstc.trec.MatlabToTREC ( format output of your ranking function so that it could be evaluated for TREC )
