4.2. Hierarchical structure of research output
The sunburst visualization provides a hierarchical view of research distribution
across three nested dimensions: department (inner ring), publication type (middle ring),
and impact classification (outer ring). The inner ring reveals remarkable balance across
departments, with each representing roughly 20% of total output. This equilibrium
suggests effective resource allocation and institutional commitment to supporting diverse
disciplinary perspectives rather than concentrating investment in a single star department.
Moving outward to publication types, journals and conferences dominate across all
departments, consistent with disciplinary norms in technical fields where rapid
dissemination through conferences complements peer-reviewed journal articles
(Kosmützky & Krücken, 2014). The presence of patents, particularly in ECE and AI Lab
segments, indicates translation of research into intellectual property and commercial
applications. This pattern aligns with institutional culture valuing innovation and
commercialization alongside theoretical contribution (Klebel et al., 2025).

The outer ring representing impact classifications shows relatively consistent
proportions of high-impact work across departments. This uniformity suggests that
research quality standards are maintained across all academic units rather than
concentrated in specific areas. No single department exhibits disproportionately high or
low impact ratios, indicating effective quality assurance mechanisms and equitable
support structures. This balanced excellence pattern differs from institutions where
research prestige concentrates in select departments while others focus primarily on
teaching or service missions.
4.3. Departmental publication preferences
The heatmap reveals nuanced patterns in publication type preferences across
departments. Computer Science shows notably high conference output (value: 102), far
exceeding other departments in this category. This pattern reflects disciplinary culture in
computer science where conferences serve as primary venues for disseminating cutting-
edge research and enjoy prestige equivalent to top-tier journals in other fields (Ghani et
al., 2022).
