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.
