This paper describes the experimentation conducted to test the effectiveness of query expansion within the logical model PLBR. We ran different experiments generating queries as logical formulas with different connectives, and using different types of linguistic information extracted from WordNet. Results show that lexical expansion is not able to improve retrieval performance. Nevertheless, the experiments allow us to conclude that query expansion can benefit from a logical model which allows structured queries. |
