Portfolio Strength & Momentum
Measuring Research Breadth, Balance & Growth Direction
The Portfolio Strength & Momentum indicator evaluates how strong, diverse, balanced, and future-ready an entity’s research portfolio is across fields, topics, and scholarly outputs.
It looks beyond single-output performance and studies whether the entity has a healthy research mix, active subject coverage, growing areas of strength, and sustainable academic momentum over time.
Within the UNIRANKS Open Index framework, this indicator helps answer one key question:
How strong, balanced, and forward-moving is this entity’s research portfolio?
Why This Indicator Matters
Strong research ecosystems are not built only on one paper, one topic, or one short-term achievement. They grow through a balanced portfolio of research activity across multiple disciplines, themes, and knowledge areas.
Some entities may be highly specialized, while others may show wide academic coverage. This indicator helps understand whether their research portfolio is expanding, stable, focused, or gaining momentum.
This creates a more complete view of research strength and future potential.
F1) Research Portfolio Diversity Score
Weight: 2%
Breadth of research activity across fields
Evaluates how widely an entity contributes across academic fields, domains, subfields, and topics.
It considers:
- Number of active research areas
- Diversity of scholarly fields
- Balance between specialized and multidisciplinary output
- Coverage across subject categories
This score helps identify entities with broad and well-developed research portfolios.
F2) Field Strength Score
Weight: 2%
Performance within key research fields
Measures how strongly an entity performs in its main academic fields compared with similar entities.
It considers:
- Strongest research domains
- Field-level output and impact
- Research visibility within subject areas
- Relative strength in specialized areas
This score highlights where an entity demonstrates clear academic excellence.
F3) Emerging Topics Momentum Score
Weight: 2%
Growth in new and fast-developing research areas
Evaluates whether an entity is contributing to new, growing, or strategically important research topics.
It considers:
- Recent growth in emerging topics
- New research directions
- Topic expansion over time
- Alignment with future-focused knowledge areas
This score helps identify entities that are adapting to new research trends.
F4) Portfolio Balance Score
Weight: 2%
Balance between mature and growing research areas
Assesses whether the entity’s research portfolio is balanced between established areas and newer areas of growth.
It considers:
- Distribution of output across topics
- Dependence on limited research areas
- Balance between old and new strengths
- Stability of the research portfolio
This score helps avoid over-reliance on one narrow research area.
F5) Research Momentum Score
Weight: 2%
Recent acceleration in research activity
Measures whether the entity’s research activity is increasing, stable, or declining over recent years.
It considers:
- Recent publication growth
- Growth rate across fields
- Sustained research activity
- Positive movement in research output
This score helps identify entities with active and growing research momentum.
