Problem Definition: Stakeholder Needs
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.

Existing Platforms
 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.

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.

Proof of Concept
Annotation of Web Content
 of exemplary, locally stored BISE degree courses websites,
implemented immediately within the HTML code
RDF Data Extraction
 via distillation and conversion of RDF data including quality control
(led to improvements in annotation)
Data Federation
 Federation of distilled data within a semantic server and merge
with the BISE schema data
Data Analysis
 Development and test of basic SPARQL queries
