Semantic Resources (RQ1): What is being evaluated?
The study reveals a growing diversity in the types of semantic resources undergoing human-centric evaluation. While ontologies remain prominent, the field has expanded to include Linked Data and Knowledge Graphs, mirroring their emergence in practical AI applications.
- Evolving Landscape: The variety of evaluated resource types has increased significantly over the years, moving beyond traditional ontologies to include more dynamic structures like Linked Data (post-2013) and Knowledge Graphs (post-2016).
- Scope of Application: Evaluations cover both general-purpose (e.g., DBpedia, Wikidata) and domain-specific resources (e.g., healthcare, manufacturing), highlighting the broad applicability and versatility of HESR.
- Reporting Gaps: A consistent challenge is the weak reporting of resource characteristics like encoding formalisms (48% not reported) and size (42% not reported), making comparative analysis difficult.
- Small Scale Bias: Most HESR instances evaluate relatively small resources, with the largest category having fewer than 500 triples. This suggests a need for methodologies scalable to larger enterprise knowledge bases.
Evaluation Process (RQ2): How is HESR performed?
Understanding the methodology of HESR is crucial for designing effective quality assurance for AI. The research identifies key aspects, frames of reference, and methods, along with critical blind spots like bias detection.
- Human-Centric Aspects: The most frequently verified aspects require human judgment, falling into intrinsic categories (e.g., semantic accuracy, completeness, consistency) and contextual categories (e.g., relevancy, suitability for application, understandability).
- Dominant Frame of Reference: "Human knowledge" serves as the primary frame of reference (89.50%) for evaluation, underscoring the indispensable role of human experts in validating semantic correctness against real-world understanding.
- Diverse Contexts: HESR is applied in various knowledge engineering contexts, including automatic knowledge extraction workflows, manual ontology construction, and improving existing resource quality (e.g., DBpedia).
- Methodological Approaches: Two main approaches emerge:
- Static Analysis (80.46%): Primarily uses subject-based experiments or expert evaluations, often supported by custom questionnaires.
- Dynamic Analysis (Less Frequent): Involves functional testing, controlled experiments, or illustrative scenarios, relying on task success, task time, and comparative methods.
- Bias Blind Spot: A significant finding is the low awareness and active addressing of potential biases in HESR. Only 12.35% of studies discuss bias, and even fewer (6.47%) implement corrective measures.
Evaluation Population (RQ3): Who is involved?
The characteristics of the human evaluators significantly influence HESR outcomes. This section details trends in population size, demographics, motivation, and expertise, offering insights into forming effective evaluation teams.
- Small-Scale Participation: The majority of HESR instances (65%) involve small evaluation populations (less than 50 participants), which limits generalizability and scalability. Larger populations typically leverage crowdsourcing or game interfaces.
- Limited Demographic Reporting: Population demographics (e.g., age, gender, country of origin) are poorly reported, with less than 20% of studies providing this crucial information, hindering an understanding of potential biases.
- Motivations for Participation: Monetary reward is the most common motivation (25.29%), followed by volunteering (5.29%) and gamification/enjoyment (4.71%).
- Expertise Spectrum: Domain expertise is reported in 47.06% of HESR, with a mix of domain experts (35.29%), medium-expertise individuals (9.41%), and laypersons (8.82%) involved. Crowdworkers (21.18%) and students (15.88%) are frequent participants.
- Knowledge Modelling Skill: This specific expertise is reported in 25.29% of HESR, indicating a need for both domain-specific and technical knowledge in evaluations.

Case Studies: Real-World HESR Applications
Explore practical examples of HESR across different contexts:
- S47 - Ontology Construction: Medical experts evaluate a human vascular system ontology (T-Box) for completeness, duplication, disjunction, and consistency through surveys, complementing automatic tools like OOPS!
- S42 - Automatic Extraction Verification: Crowdworkers validate automatically extracted medical knowledge triples from PubMed abstracts for domain correctness, using multiple-choice tasks against a gold standard.
- S1 - Resource Quality Improvement: Mixed-expertise crowds (experts and crowdworkers) identify quality issues in DBpedia triples (incorrect object values, datatypes, links) through a Find-Verify workflow.
- S18 - Task Support: Students evaluate an IoT device programming ontology (EUPont OWL) in a controlled experiment, measuring its impact on efficiency and effectiveness of rule definition tasks via a custom interface.
