Are there 2 extended Epinions datasets?
Hi Paolo, thank you for the welcome note! My PhD student Patricia Victor told me that you shared with her an extended Epinions dataset, with trust and distrust links, that does not match the extended Epinions dataset on the wiki. The trust graphs have the same size, but there is a significant difference in the number of ratings. Will you make this other extended dataset available on the trustlet wiki too at some point?


 * uhm, I might have made some mistake in reporting information about the dataset on the wiki then, because I only have one extended Epinions dataset. Would you be so kind to write here the significant differences in the number of ratings between what I reported and the dataset I gave you? In this way I can try to find where the error is. Thanks!!! I hope you are having fun with the dataset ;) --PaoloMassa 02:14, 24 December 2008 (PST)

The data set that you sent to Patricia has 25.346.057 ratings (the gz-file is 167MB) while the one on trustlet has only 13.668.320 ratings (85 MB). Thank you in advance for solving this mystery!
