Results

19

To evaluate how relevant is the information displayed by infrastructure awareness systems.A

To identify which of the users interests infrastructures awareness systems do not take into account.BTo identify elements of re-design in the infrastructures themselves so as to improve their adoptability.C

Relevant: machines and people associated to them No Relevant: the details of task distribution.

Algorithms, input data and parameters

Task execution results (numeric or graphical)

Closure Analisys

• Which of the infrastructure features being shown, but not relevant (e.g. bidding activity);

• Which of the infrastructure features not being shown, but relevant (e.g. the data used to execute a task);

• Which elements of interest the awareness system could display to engage people even though not supported by the infrastructure (e.g. latest publications).

• Which elements of the infrastructure were missing to answer users’ interests (e.g. sharing of results).
