This paper describes an experiment aiming at evaluating the role of NLP based optimizations (i.e. morphological derivation and synonymy expansion) in web search strategies. Keywords and their expansions are composed in two different Boolean expressions (i.e. expansion insertion and Cartesian combination) and then compared with a keyword conjunctive composition, considered as the baseline. Results confirm the hypothesis that linguistic optimizations significantly improve the search engine performances.

Abstract
This paper describes an experiment aiming at evaluating the role of NLP based optimizations (i.e. morphological derivation and synonymy expansion) in web search strategies. Keywords and their expansions are composed in two different Boolean expressions (i.e. expansion insertion and Cartesian combination) and then compared with a keyword conjunctive composition, considered as the baseline. Results confirm the hypothesis that linguistic optimizations significantly improve the search engine performances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
