Hello, I would like to ask you if you know any sequential dataset which contains sequences of items along with descriptive attributes for each item in the sequence. Thank you

This is very helpful. Thank you a lot for your detailed response. I have also read your blog post yesterday concerning the equation that you propose for choosing minsup, and I find it very useful. jbd

Hello, Concerning your paper: "Fast Vertical Mining of Sequential Patterns Using Co-occurrence Information", I would like to ask you on what basis did you make your choice of the values of minsup for each dataset ? Thank you, jbd

Hello, As to your knowledge, is there any pattern growth-based sequential pattern mining algorithm that has a vertical database representation? Until now I haven't found anyone neither in your survey nor in the literature, so I wonder if such an algorithm exists or can be done. Thank you

Good morning, Thank you for this explanation. I believe that you meant to mention that GSP uses a horizontal database representation as it is mentioned in your survey. Best regards,

Hello, I have a question, please. As we know, we have horizontal and vertical database representation in the domain of sequential pattern mining. My specific question: Are database projection algorithms considered within the category of horizontal database representation or is it considered as a third category? Thank you

Hello, I would like to ask you if, based on your knowledge, there exists any dataset that contains sequential data as well as additional descriptive data to each element in the sequence. For example, a sequence of activities of users (represented by user id) contains activities performed by the user across time (only the order of activities is important to me for the moment and not necessarily

Hello, Is there any dataset for the seqdim algorithm where it contains multi-dimensional and sequential data? Thank you

Hello Prof. Philippe, I am interested in sequential pattern mining with multiple supports because I need to obtain infrequent patterns that may contain important information and that is lost in traditional sequential pattern mining algorithms. I would like to ask you if there exist any algorithm in SPMF that mines sequential data with multiple supports. I would also like to know your opinion

Dear Prof. Philippe, I have a question please. Is there an algorithm among the traditional sequential pattern mining algorithms that stores all the occurrences of a pattern in each sequence, or they all consider one occurrence of it? (and more precisely a vertical one) Thank you, jbd

Hi Prof. Philippe, Thank you for your response. Yes, in fact it would be perfect to have it because this is exactly what I need for my work! I thank you a lot for that. Best regards, jbd

Dear Prof. Philippe, Dear Francicso, This topic is interesting as I am working on something very similar and need to get extra information about a frequent sequence as well. I would like to ask Francicso if he had found any relevant solution to this problem by now. And I would also like to ask Prof. Philippe whether SPADE algorithm that stores the id-lists of sequences already has a solutio
