WP6 face-to-face meeting in Stuttgart on 2008-10-14

Participants:

• Cefriel: Emanuele, Irene
• Saltlux: Kono, Tony, Stanley
• VUA: Zhisheng

Discussion

• M9 - D6.2 - Templates of periodic report on data and performances
  • Stefano Bertolo asked for measuring the progress of the work in the project wrt parameters and metrics over the use case
  • from the discussion with WP5, we can think about QoS parameters and things like those
  • this will also be used for M12 - D6.4 - 1st periodic report on data and performances
• M12 - D6.3 - Urban Computing environment specification

  • chicken&egg problem with technical WPs, in particular with WP5

  • Dieter proposal in TMB meeting: just a mock-up & paper for M12

  • change the name to "First Urban Computing Service Mockup" --> demonstrator, data and paper

    • in this case, we must have a plan for the mockup within M8 --> (1) to use Saltlux UCity with Larkc; (2) to build www.linkedurbandata.org exposing as SPARQL endpoint the public data we collected; (3) possibly, to overlap the two things at least partially

    • we can also use this mockup as a WP4 plugin test (as suggested by Zhisheng), as a C-SPARQL test (for the Cefriel-Polimi group working on it), etc.
  • TASKS: (1) what are those (to-be-linked) urban data? (2) what is the storyboard behind the mockup? starting from the current storyboards
• Current storyboard steps and requirements for the mockup (cf. Emanuele presentation)
  1. just a form to enter data
  2. some various constraints:
     • we don't have data ready from Italian railways, subway and car traffic
     • we do not use temporal reasoning (no ontology of time)
     • we have to check a place where we have timetables of train and subway, road network (street topology) and traffic

     • but without information like commuters traffic, i.e. time needed to follow a link on the path --> maybe Siemens can compute the "weight" of the links for different periods of the day? only if loosely coupled

     • multiple-transportation travel planning (even if something is made by us and something invoked from external services),
     • traveling costs, user preferences (e.g., first class rather than second class on trains, cheapest, fastest, ...);

     • --> priority of choices: (1) check the data, (2) everything without travel costs and user preferences, (3) if we succeed, also costs and preferences

  3. ok

  4. the system stores the travel plans and alert if something changes and makes the chosen option no longer valid --> it is a trigger fired by some change in the assumptions; no problem for the mockup (it is a user preference)

  5. is it possible to get "real-time" updates of the data to be alerted? we need a way to "feed" the system with e.g. accident data --> ok, but with faked events (not real, but realistic and inserted on purpose)

  6. no, this is very hard --> simplify: a delay invalidates the plan

  7. ok, with (optional) explanation of why the plan is no longer valid (with fake SMS to alert and without the parking ticket thing)
  8. not the SMS, but the user checks the alternatives on the web interface (e.g. on his smart phone)
  9. maybe, but only if Siemens wants to create a separate prediction demonstrator with the weather as well
  10. ok
  11. it is not necessary to find the cheapest gas station
  12. no season/holiday/weather conditions, but car accident and road re-planning (one plan is mandatory, multiple alternative plans are optional)
  13. ok

  14. no metro, but Carlo arrives in time
