"Contextual Query Using Bell Tests “

Abstract : Tests are essential in Information Retrieval and Data Mining, in order to evaluate the effectiveness of a query. An automatic measure tool intended to exhibit the meaning of words in context has been developed and linked with Quantum Theory, particularly entanglement. “Quantum like” experiments were undertaken on semantic space based on the Hyperspace Analogue Lan-guage (HAL) method. A quantum HAL model was implemented, using state vectors issued from the HAL matrix and query observables, testing a wide range of window sizes. The Bell parameter S, associating measures on two words in a document was derived, showing peaks for specific window sizes. The peaks show maximum quantum violation of the Bell inequalities and are document dependent. This new correlation measure inspired by Quantum Theory could be promising for measuring query relevance.
