  9. 9. International Symposium on Decision Support Systems · Cairo · December 2015 Page 9 Problem Definition: Stakeholder Needs Vera G. Meister · A Semantic-web-based Decision Support System for Specific Degree Programs Dec-15 BISE degree course: We want our course offers be found and to be comparable with other degree courses with respect to their structure and content. Prospective BISE student: I want to study BISE and I want to know which universities of applied sciences offer such courses and what are their focuses. Faculty member: I want to contact a colleague from a university of applied sciences in the federal state XY who is also teaching in a degree course of BISE. Enterprise/Organization: For the reinforcement of our project team we are looking for interns / graduates BISE with particular qualifications. Project sponsor/Centre of knowledge transfer: In the context of a tender for innovation transfer to regional business we are looking for universities of applied sciences with competences in BISE.
  10. 10. International Symposium on Decision Support Systems · Cairo · December 2015 Page 10 Existing Platforms Vera G. Meister · A Semantic-web-based Decision Support System for Specific Degree Programs Dec-15  More than 50 platforms are around  Most important: “University compass” sponsored by the German Rectors' Conference (GRC), based on central relational database. Allows to search for: • general type of degree course (bachelor or master); • formal course characteristics, like teaching language, start date, and accreditation; • general study subject via inserting a search term and selecting categories; • organizational formats, like full time, part time, double degree, extra occupational; • geographical features, like place, ZIP code, and state; • access criteria for persons without high school diploma, e. g. multi-annual professional experience, non-academic examinations; • institutional type of the university: private or public, traditional university or university of applied sciences.  What is missing: subject specific information about degree courses  None of this platforms offers structured open data.
  11. 11. International Symposium on Decision Support Systems · Cairo · December 2015 Page 11 Approach to a Solution Three Alternative Approaches:  All based on Semantic Web Technology and a BISE ontology 1. Data shall be extracted from the central relational database of the GRC. They shall be transformed to RDF and semantically enriched based on BISE ontology. A specific search application allows flexible analysis. 2. Interested universities or departments annotate the web content of their degree course pages based on the BISE ontology. A web service crawles regularly the data and stores it in a triple store. The search application is designed like in variant 1. 3. A Web crawler goes regularly through all openly available websites and documents. Using a natural language processing component the crawled content shall be analyzed and the extracted data stored according to the BISE ontology (Big Data approach) - search application like in variant 1.
