In this work, we propose a method for document re-ranking, which exploits negative feedback represented by non-relevant documents. The concept of non-relevance is modelled through the quantum negation operator. The evaluation carried out on a standard collection shows the eectiveness of the proposed method in both the classical Vector Space Model and a Semantic Document Space.

Abstract
In this work, we propose a method for document re-ranking, which exploits negative feedback represented by non-relevant documents. The concept of non-relevance is modelled through the quantum negation operator. The evaluation carried out on a standard collection shows the eectiveness of the proposed method in both the classical Vector Space Model and a Semantic Document Space.File in questo prodotto:
