Corrigendum to “Recommender system based on pairwise association rules” (Expert Systems With Applications (2019) 115 (535–542)

The authors regret to inform that the manuscript “Recommender system based on pairwise association rules” provides an incorrect parameter in line “To gather as many association rules as possible we set both the minimum support and the minimum confidence to the lowest value (3 × 10⁴) that allows the completion of the mining process of our data set on our machine within a time limit of 5 minutes.” The actual number should be (3 × 10⁻⁴, three multiplied by ten to the power of minus four). The mistake occurred in the process of generating a pdf document from a latex source file and was not recognised in reviewing process. The authors would like to apologize for any inconvenience caused.
