  5. 5. International Symposium on Decision Support Systems • Cairo • December 2015 55 Use Cases and Requirements Meister, Jetschni: Towards a Semantic Information System for IT Services 2015-12-12 want to have guidance on public IT services at university  e. g. as prospect students, as potential project partners of the university etc. need information about a specific IT service  e. g. about access conditions, service options, support offerings, operational processes etc. aim on central coordination and standardization of services  e. g. for efficient appointment of scarce resources, for optimal support for IT management processes etc. need reliable data about costs and expenses of IT services  e. g. for budget planning, for implementing an internal transfer pricing system for shared IT services etc.

  8. 8. International Symposium on Decision Support Systems • Cairo • December 2015 88  Who acts in a service? Is that a person, an organization, or a role?  Are there relations between those actors?  In which relation (user, provider, customer, or supporter) does someone act in a service?  Which entities (IT assets, documents) are associated with a service?  Are there relations between one service and others?  How can a service be evaluated in terms of priority and criticality?

International Symposium on Decision Support Systems • Cairo • December 2015 1313 Development of SPARQL Queries Meister, Jetschni: Towards a Semantic Information System for IT Services 2015-12-12 As easy as possible. Rule 1 As comprehensive as possible. Rule 2 As general as possible. Rule 3 Specify the target graph pattern and translate it into SPARQL. 2 Define the question in natural language.1 Add filters, constraints, or aggregations.3 Specify filters for language(s) and/or data types. 4 Check, evaluate, and modify the results.5

  15. 15. International Symposium on Decision Support Systems • Cairo • December 2015 1515 Appreciated by Evaluators Meister, Jetschni: Towards a Semantic Information System for IT Services 2015-12-12 Chancellor Professor Head of Lab Services Controller Student Reports allow better control of the organization, e. g. in terms of review of contracts with extern providers. The tool may be very helpful during on boarding. We could implement a ticket system for all users. We could check the involvement of staff into IT services and allocate costs according to the cost-by-cause principle. It‘s convenient to have all services for students in one place.
