My dataset is the result of multiple joins from large transactional database stored in a MySQL database. There are some columns with text value and double values. I am trying to do a first level sequential pattern mining on this dataset using SPMF.

  1. Is it possible to give words as input in SPMF? The documentation tells that only positive integers are allowed.
  2. If I want to give words or decimal numbers, which software/package shall I use?



Thanks for using SPMF. I'm the founder of that library. Currently, SPMF does not support text files containing some text as input. Thus, users need to do some preprocessing to convert the text file to the format used by SPMF. But in the future, it is my plan to add the feature of handling text files natively in SPMF. It will likely be added in the next few weeks, depending on my schedule.

By the way, if you have any question about SPMF, you can also directly ask them on the forum on the SPMF website. Then, I will answer you more quickly.
