Hi, I'm trying to test the result in the paper Session-Based Social Recommendation on the Delicious datasets . From the paper and datasets, I understand that you consider each session is a sequence of tags a user has assigned to a bookmark and all the tagging actions for that bookmark will have the same timestamp according to the datasets. So my question is that when you give the time_id for each session (as in the preprocess_DoubanMovie.py file), will two sessions have the same id only if their timestamps have exactly same date and time ? E.g: A session with timestamp '01/06/2020 2:30:00 pm' and another session with timestamp '01/06/2020 2:30:01 pm' will have different time_id.

If I remember correctly, you are right that two session have the same time_id only if their date and timestamps are exactly the same. Please let me if you still have question on this.
