QUERY EXPANSION WITH MATRIX CORRELATION TECHNIQUES - A Systematic Approach

Abstract

This paper presents an Information Retrieval system that employs techniques based on Personalization and Query Expansion (QE). The system was developed in an incremental and iterative way, starting from a simpler system and reaching a more complex one, to the point that it is possible to talk about several systems each based on a specific, deeply analyzed approach: four systems sharing the concept of term co-occurrence. Starting from a simple system based on bigrams, we moved onto a system based on term proximity, through an approach known in the literature as Hyperspace Analogue to Language (HAL), and eventually developing a solution based on co-occurrence at page level. The latter presents a hybrid approach based on term proximity. This novel architecture is shown here for the first time to our knowledge.
