My recent paper on #LTLf #logic and #TemporalModelMining through #RelationalAlgebra for temporal reasoning is out: https://www.mdpi.com/2078-2489/14/3/173

Interesting applications involve #CyberSecurity #Industry40 and #eHealth

If you are in #NewcastleUponTyne, I'm going to present both #KnoBAB and the general topic of #BusinessProcessManagement in next week's North East Data Scientists #MeetUp: https://www.meetup.com/it-IT/newcastle-upon-tyne-data-science-meetup/events/291615728/ See you there!

I'm not only a Bash guy: I really like databases too!

If you need a formal introduction to relational algebra here is a presentation on the topic by the great Pr. Jeffrey D. Ullman:

http://infolab.stanford.edu/~ullman/fcdb/aut07/slides/ra.pdf

Pay special attention to:
- pp11-14 describing the product ("CROSS JOIN" in SQL) theta-join ("JOIN ... USING" or "JOIN ... ON" in SQL)
- pp29-31 explaining the core difference between genuine relational algebra and SQL (set vs. bag algebra)
