Examples with the Paraphraser

 

These queries demonstrate the use of the paraphraser. The option to paraphrase is always turned on in the online demonstration. However, due to problems with quantifier scoping, the algorithm is not able to paraphrase all queries successfully. Also, the paraphraser operates at the level of the Tuple Relational Calculus so unsuccessful interpretations are not paraphrased.
