Information retrieval techniques model formulations and algorithmic solutions to the problems

Abstract

The goal of the thesis is to understand the contributions of concrete newlineareas such as framework efficiency variability factors and query variability newlinefactors to overall retrieval variability This brought together four different newlineInformation Retrieval IR models and set them to improve effectiveness newlineperformance Then for each designated model a detailed analysis of each newlineframework with its retrieved documents was done and observations have newlineyielded hypotheses for individual model and are tested in experiments newline newline
