This works presents a software solution for enhancing inverted file compression based on the reassignment of document identifiers. We introduce different techniques recently presented in the Information Retrieval forums to address this problem. We give further details on how it is possible to perform the reassignment efficiently by applying a dimensionality reduction to the original inverted file and on the evaluation results obtained with this technique. This paper is devoted to the software architecture and design practises taken into account for this particular task. Here, we show that making use of design patterns and reusing software components leads to better research applications for Information Retrieval.
