I am happy to announce that this Thursday (the 20th of January), Florian Bock will hold the discussion about “stiEF - Working with natural language traffic scenario descriptions”.
Also, remember that we changed the link to join the Meetup!
The development of modern driving assistance systems is a key factor within the overall vehicle development, but as well a very complex task. An essential part of the applied processes is the topic of the safety of the function, i.e. the methods applied to ensure its reliability. For simple functions with very limited sensor and actor data input/output such as PDC (Park Distance Control) or ABS (Anti Braking System), the number of required test cases to “prove” the reliability was manageable and reasonable. Driving functions that fully take over the driving task for an extensive period of time face an uncountable number of possible situations that they have to deal with. In this case, it is no longer enough to test based on simple sensor data and inputs/outputs. Instead, an abstract artefact is required to describe the surroundings of the vehicle – a traffic scenario. These scenarios are then used throughout the whole development process – in the specification, the implementation and in testing. Whereas concrete test scenarios can be formulated in common formats such as OpenSCENARIO, natural language scenarios used, e.g., in the function specification, for legal purposes or for test driver instructions, are not standardized at all yet. They are manually created as text artefacts and therefore lack a common grammar, automatic translation and a congruent visualization. Therefore, the domain specific language and the corresponding tool stiEF were created, which will be presented in this talk. stiEF supports natural language scenario descriptions with different translations, an automatically generated scenario visualization and the possibility to export the underlying scenario data into different target formats for further utilization. Also, some insights are given in the difficulties with trying to encapsulate natural language descriptions into a formalized domain specific language.
Dr. Florian Bock studied Computer Science with a focus on Software Engineering for Embedded Systems at the University of Applied Sciences in Ingolstadt. He received his Diploma (FH) in 2011 and Master of Science in 2014. Afterwards, he gained his Ph.D. in 2020 at the Friedrich-Alexander University Erlangen-Nuremberg with his thesis about domain specific languages for specification purposes. He has been working for more than 10 years within the Volkswagen Group and is currently focusing on scenario creation, management and usage. One essential part of that is the development and maintenance of the scenario creation language and tool stiEF.
After registering, you will receive a confirmation email containing information about joining the meeting. It will also permit you to add it to your calendar.
It is hosted on Zoom at 6 PM GMT+1/CEST (you can use this link to figure out which time is in your timezone: Dateful Time Zone Converter).
I am also happy to extend the invitation to the MDENet Annual Symposium online on the 26th and 27th of January 2022. The event is free to attend so reserve your place here. There will be tutorials, challenge talks, informal networking sessions, roundtables and ample opportunity to mix with other like-minded people from the MDE world. Also, there will be a wide range of sessions including keynote speakers: Tony Clark, Aston University; Balbir Barn, Middlesex University or Mohammadreza Mousavi, King’s College.
P.S. We get a recurring question: “Are presentations recorded?”. The answer is not, and the reasons are explained here On recording Virtual Meetups - #7 by voelter
