Abstract

The article advocates for a more comprehensive evaluation method for Large Language Models (LLMs) by combining traditional automated metrics (BLEU, ROUGE, and Perplexity) with structured human feedback. It highlights the limitations of standard evaluation techniques while emphasizing the critical role of human assessments in determining contextual relevance, accuracy, and ethical appropriateness. Through detailed methodologies, practical implementation examples, and real-world case studies, the article illustrates how a holistic evaluation strategy can enhance LLM reliability, better align model performance with user expectations, and support responsible AI development.

1 Introduction

The artificial intelligence application domain underwent a fundamental transformation because of Large Language Models (LLMs), including GPT-4, Claude, Gemini, and other models. The extensive use of these models requires complete evaluation through comprehensive assessment methods. The evaluation of these models depends mainly on automated metrics, which include BLEU, ROUGE, METEOR, and Perplexity. Research findings demonstrate that automated evaluation metrics fail to accurately predict user satisfaction and model effectiveness. A complete evaluation framework requires the combination of human feedback with traditional metrics for assessment. This paper demonstrates a complete method to evaluate LLM performance by merging quantitative metrics with human feedback assessment. This paper examines existing evaluation method restrictions while explaining human feedback value and presents integration approaches with practical examples and code illustrations.

2 Limitations of Traditional Metrics

The traditional metrics served as standardized benchmarks for earlier NLP systems, yet they do not measure the semantic depth, contextual appropriateness, and creative capabilities that define modern LLMs. Traditional metrics for evaluating LLMs mainly include:

  • BLEU (Bilingual Evaluation Understudy) ( Papineni, Roukos, Ward, & Zhu, 2002)  BLEU
  • ROUGE (Recall-Oriented Understudy for Gisting Evaluation) (Lin) ROUGE
  • METEOR (Metric for Evaluation of Translation with Explicit Ordering)
  • Perplexity

The evaluation metrics provide useful information, yet they have several drawbacks:

  • Lack of Contextual Understanding: BLEU and similar metrics measure token similarity, yet they fail to assess the contextual meaning of generated text.
  • Poor Correlation with Human Judgment: High automated scores do not necessarily lead to high user satisfaction according to human judgment.
  • Insensitivity to Nuance and Creativity: These evaluation metrics fail to detect nuanced or creative outputs , which remain essential for practical applications.

The evaluation metrics of LLM—BLEU, ROUGE, perplexity, and accuracy—were developed for specific NLP tasks but fail to meet the requirements of contemporary language models. The IBM BLEU scores demonstrate a weak relationship with human assessment (0.3-0.4 for creative tasks), and ROUGE correlation ranges from  0.4-0.6 based on task complexity. The metrics demonstrate semantic blindness because they measure surface-level word overlap instead of detecting semantic equivalence and valid paraphrases. (Clement, 2021) Clementbm, (Dhungana, 2023) NLP Model Evaluation, (Mansuy, 2023) Evaluating NLP Models

Perplexity faces the same challenges as other metrics despite its common application. The metric’s reliance on vocabulary size and context length creates unreliable cross-model comparisons and its focus on token prediction probability does not measure the quality of generated content. (IBM, 2024) IBM. Studies demonstrate that models with lower perplexity scores do not automatically generate more helpful or accurate or safe outputs, explaining the gap between optimization targets and real-world utility. (Devansh, 2024) Medium

The evaluation system has multiple limitations which affect both individual metrics and basic assumptions about evaluation. The traditional evaluation methods depend on perfect gold standards and single correct answers, but they do not consider the subjective nature of language generation tasks  (Devansh, 2024) Medium. BERTScore and BLEURT, although they use neural embeddings to capture semantic meaning, still have difficulty with antonyms, negations, and contextual subtlety (Oefelein, 2023) SaturnCloud. The study demonstrates that advanced automated metrics fail to measure human language complexity completely. The recent advancements in neural metrics have tried to solve these problems (Bansal, 2025) AnalyticsVidhya (Sojasingarayar, 2024) Medium. xCOMET achieves state-of-the-art performance across multiple evaluation types with its fine-grained error detection capabilities. The xCOMET-lite compressed version maintains 92.1% quality while using only 2.6% of the original parameters. The improvements function within automated evaluation limitations which require human feedback for complete assessment (Guerreiro, et al., 2024) MIT Press, (Larionov, Seleznyov, Viskov, Panchenko, & Eger, 2024) ACL Anthology.

2.1 Example Limitation:

The expected answer to the question “Describe AI” should be:

“The simulation of human intelligence processes through machines defines AI.”

The LLM generates an innovative response to the question:

“The power of AI transforms machines into thinking entities which learn and adapt similarly to human beings.”

The traditional evaluation methods would give this response a lower score even though it has greater practical value.

3 The Importance of Human Feedback

Human feedback connects to automated evaluation gaps by directly evaluating the usefulness and clarity and creativity and factual correctness and safety of generated outputs. Key advantages include:

  • Contextual Understanding: Humans evaluate if answers make logical sense in given contexts.
  • Practical Relevance: Directly assesses user satisfaction.
  • Ethical Alignment: Evaluates ethical implications, biases, and appropriateness of generated outputs.

Human feedback evaluation requires scoring outputs based on qualitative assessment criteria.

Metric

Description

Accuracy

Is the provided information correct?

Relevance

Does the output align with user intent?

Clarity

Is the information communicated clearly?

Safety & Ethics

Does it avoid biased or inappropriate responses?

4 Integrating Human Feedback with Traditional Metrics

The combination of automated assessment with human feedback in recent research shows preference alignment at 85-90% while traditional metrics alone reach only 40-60% according to (Pathak, 2024) Red Hat, which transforms our current methods of AI performance evaluation. The new approach demonstrates how LLMs need assessment frameworks that evaluate accuracy together with coherence and safety and fairness and human value alignment. Effective assessment of LLM composites requires the combination of automatic techniques with subjective annotations. One can envisage a strong solution as illustrated in Figure1

Figure 1: Holistic LLM Evaluation PipelineFigure 1: Holistic LLM Evaluation Pipeline

The shift from automated evaluation to human-integrated approaches goes beyond methodological enhancement because it tackles essential issues in our current understanding of AI performance. The emergence of reinforcement learning from human feedback (RLHF) and constitutional AI and preference learning frameworks represent new evaluation methodologies which focus on human values and real-world applicability instead of narrow performance metrics (Dupont, 2025) Labelvisor, (Atashbar, 2024) IMF eLibrary, (Huyen, 2023) RLHF.

RLHF achieves outstanding efficiency through its training of 1.3B parameter models with human feedback which surpasses 175B parameter baseline models while optimizing alignment to reach 100x parameter efficiency (Lambert, Castricato, Werra, & Havrilla, 2022) Hugging Face. The system functions through three sequential stages which include supervised fine-tuning followed by reward model training from human preferences and reinforcement learning optimization through proximal policy optimization (PPO) (Dupont, 2025) Labelvisor, (Huyen, 2023) RLHF.

The methodology works effectively because it detects subtle human preferences which standard metrics fail to detect. Human evaluation demonstrates that RLHF-aligned models receive 85%+ preference ratings above baseline models while showing significant improvements in helpfulness and harmlessness and honesty. The reward model training process employs 10K-100K human preference pairs to develop scalable preference predictors which direct model behavior without needing human assessment for each output (Lambert, Castricato, Werra, & Havrilla, 2022) Hugging Face.

The implementation of human-in-the-loop (HITL) systems establish dynamic evaluation frameworks through human judgment that directs automated processes. These systems achieve 15-25% improvement in task-specific performance while reducing safety risks by 95%+, operating through intelligent task routing that escalates uncertain or potentially harmful outputs to human reviewers. The method demonstrates its best results in specialized fields of legal review and medical diagnosis because AI pre-screening followed by expert validation produces efficient and rigorous evaluation pipelines. (Greyling, 2023) Medium, (SuperAnnotate, 2025) SuperAnnotate, (Olivera, 2024) Medium

4.1 Practical Implementation (With Code Example)

A basic framework for human feedback integration with automated metrics can be implemented through Python code.

Step 1: Automated Metrics Calculation.

from nltk.translate.bleu_score import sentence_bleu 
from rouge import Rouge

reference = "AI simulates human intelligence in machines." 
candidate = "AI brings intelligence to machines, allowing them to act like humans."

#Calculate BLEU Score
bleu_score = sentence_bleu([reference.split()], candidate.split())

#Calculate ROUGE Score
rouge = Rouge() 
rouge_scores = rouge.get_scores(candidate, reference)

print("BLEU Score:", bleu_score) 
print("ROUGE Scores:", rouge_scores)

Output for above

BLEU Score: 1.1896e-231 (≈ 0)

Rouge Score : [
    {
        "rouge-1": {
            "r": 0.3333333333333333,
            "p": 0.2,
            "f": 0.24999999531250006
        },
        "rouge-2": {
            "r": 0.0,
            "p": 0.0,
            "f": 0.0
        },
        "rouge-l": {
            "r": 0.3333333333333333,
            "p": 0.2,
            "f": 0.24999999531250006
        }
    }
]

These results highlight:

  • BLEU’s brittleness: nearly zero due to no matching 4 grams which means very poor on every dimension.
  • ROUGE-1 and ROUGE-L capture basic overlap (unigrams/LCS), but ROUGE-2 is zero since there are no matching bigrams.

Step 2: Integrating Human Feedback

Suppose we have human evaluators scoring the same candidate output:

#Human Feedback (Collected from Survey or Annotation)
human_feedback = { 
'accuracy': 0.9, 
'relevance': 0.95, 
'clarity': 0.9, 
'safety': 1.0 }

#Aggregate human score (weighted average)
def aggregate_human_score(feedback): 
    weights = {'accuracy':0.3, 'relevance':0.3, 'clarity':0.2, 'safety':0.2} 
    score = sum(feedback[k]*weights[k] for k in feedback) 
    return score

human_score = aggregate_human_score(human_feedback) 
print("Aggregated Human Score:", human_score)

Out for above

Aggregated Human Score: 0.935

The aggregated human score of 0.935 indicates your LLM output receives extremely high ratings from real people which exceeds typical “good” thresholds and makes it suitable for most practical applications or publication with only minor adjustments for near perfect alignment.

Step 3: Holistic Aggregation

Combine automated and human scores:

#Holistic Score Calculation
def holistic_score(bleu, rouge, human): 
    automated_avg = (bleu + rouge['rouge-l']['f']) / 2 
    holistic = 0.6 * human + 0.4 * automated_avg 
    return holistic

holistic_evaluation = holistic_score(bleu_score, rouge_scores[0], human_score) 
print("Holistic LLM Score:", holistic_evaluation)

Output for above

Holistic LLM Score: 0.6109999990625

Holistic LLM Score of 0.6109999990625 reflects a weighted blend of:

  1. Automated Metrics (BLEU & ROUGE-L average) 40 % weight
  2. Aggregated Human Score — 60 % weight A score of ~0.611 requires explanation along with guidance on how to proceed.

4.1.1. How the Score Was Computed

  • The human score (0.935) had a weight of 60% which means it contributed 0.561 to the final score.
  • The automated average score was calculated by taking the average of BLEU ≈ 0 and ROUGE L F1 ≈ 0.2478 which equals 0.1239 and this score had a weight of 40% which means it contributed 0.0496 to the final score.
  • The total score was approximately 0.6109999 when rounded to 0.6106.

4.1.2. Interpreting 0.611 on a 0–1 Scale

  • The performance level would be considered “poor” when the score falls below 0.5.
  • The model receives high human ratings, but rigid lexical metrics score it at the low end of the range when the score falls between 0.5 and 0.7.
  • Most applications consider scores above 0.8 as “strongly acceptable.”

The score of 0.611 places you in the moderate range.

  • The output received high praise from human evaluators regarding accuracy and relevance and clarity and safety.
  • The automated metrics strongly penalized the output because it had low exact n-gram overlap.

4.1.3. Why the Hybrid Score Is Lower Than the Human Score

  • The automated component receives a score of 0 because BLEU has no 4-gram overlap.
  • The ROUGE-L F1 score of 0.2478 is also quite low for the same reason.
  • The human rating of 0.935 does not prevent the automated 40% slice from lowering the overall score to approximately 0.61.

4.1.4. Practical Takeaways

  • Trust the Human Rating First

    • The human score indicates the content quality within its specific context.
    • Your current focus on user satisfaction indicates you are already meeting your goals.
  • Decide Your Threshold

    • Your automated metrics require improvement even though your production readiness threshold is ≥ 0.7.
    • Your automated tasks are ready for deployment when their scores reach 0.6 or higher regardless of their nature.
  • Improve Automated Scores

    • Lexical overlap: Reuse more of the reference phrasing or add synonyms that match it.
    • Smoothing: For BLEU, try smoothing functions (e.g., SmoothingFunction.method1) to avoid zero scores. o Semantic metrics: Consider swapping or augmenting BLEU/ROUGE with BERTScore or BLEURT, which better capture meaning.
    • Semantic metrics: Consider swapping or augmenting BLEU/ROUGE with BERTScore or BLEURT, which better capture meaning.
  • Adjust Weighting (if appropriate)

    You could reduce the automated weight (e.g., 30 % auto / 70 % human) if you trust human feedback more for your use case.

5 Recent research advances holistic evaluation frameworks

During 2023-2025 researchers developed complete evaluation frameworks for LLMs which addressed the complex aspects of language model performance. The Holistic Evaluation of Language Models (HELM) framework achieved 96% coverage improvement over previous evaluations as Stanford researchers evaluated 30+ prominent models across 42 scenarios and 7 key metrics including accuracy, calibration, robustness, fairness, bias, toxicity, and efficiency. (Stanford, n.d.) Stanford.

The Prometheus evaluation system and its successor Prometheus 2 represent major advancements in open-source evaluation technology. Prometheus 2 demonstrates 0.6-0.7 Pearson correlation with GPT-4 and 72-85% agreement with human judgments which enables both direct assessment and pairwise ranking. The framework offers accessible proprietary evaluation system alternatives with performance standards that match leading commercial solutions (Kim, et al., 2023) Cornell, (Liang, et al. 2025)OpenReview, (Wolfe, 2024) Substack.

The G-Eval framework implements chain-of-thought reasoning to evaluate processes through form-filling paradigms for task-specific metrics.  The framework delivers better human alignment performance than traditional metrics according to Confident AI because transparent reasoning-based evaluation reveals complex language generation aspects that automated metrics fail to detect. The evaluation method delivers exceptional benefits for tasks which need multiple reasoning steps or creative output capture (Wolfe, 2024) Substack, (Ip, 2025) Confident AI. The development of domain-specific evaluation methods demonstrates how experts now understand that general-purpose assessment tools fail to measure specialized applications properly. FinBen provides 36 datasets that span 7 financial domains and   aggregates healthcare-focused benchmarks to allow precise evaluation of domain-specific capabilities. Evidently AI These frameworks incorporate specialized knowledge requirements and professional standards that general benchmarks cannot (Zhang et. al, 2024) Cornell, (Jain, 2025) Medium.

The MMLU-Pro benchmark addresses the 57% error rate found in the original MMLU benchmark through expert validation and increased difficulty from 10-choice questions. The field’s growth leads to ongoing evaluation standard development which reveals problems in current benchmark systems.

6 Real-world Use Case:

6.1 ChatGPT Evaluation

OpenAI uses Reinforcement Learning from Human Feedback (RLHF) to improve GPT models. Human evaluators assess model outputs and the scores they provide are used to train a reward model. The combination of these methods resulted in a 40% improvement in factual accuracy compared to GPT-3.5, Practical usability and model responses that match human expectations, leading to a much better user experience than automated evaluation alone. They use continuous monitoring through user feedback and automated safety. (OpeinAI, 2022)OpenAI.

6.2 Microsoft’s Azure AI Studio

The Azure AI Studio from Microsoft integrates evaluation tools directly into its cloud infrastructure which allows users to test applications offline before deployment and monitor them online during production. The platform uses a hybrid evaluation method which pairs automated evaluators with human-in-the-loop validation to help businesses preserve quality standards during application scaling. The Prompt Flow system from their company allows users to evaluate complex modern AI applications through multi-step workflow evaluation (Dilmegani, 2025) AIMultiple.

6.3 Google’s Vertex AI

The evaluation system of Google’s Vertex AI demonstrates the development of multimodal assessment which evaluates performance across text, image and audio modalities. Their needle-in-haystack methodology for long-context evaluation has become an industry standard, enabling scalable assessment of models’ ability to retrieve and utilize information from extensive contexts. The approach proves particularly valuable for applications requiring synthesis of information from multiple sources (Dilmegani, 2025) AIMultiple.

6.4 Other Case studies

The commercial evaluation landscape has expanded significantly, with platforms like Humanloop, LangSmith, and Braintrust offering end-to-end evaluation solutions. These platforms typically achieve 60-80% cost reduction compared to custom evaluation development, providing pre-built metrics, human annotation workflows, and production monitoring capabilities. Open-source alternatives like DeepEval and Langfuse democratize access to sophisticated evaluation tools, supporting the broader adoption of best practices across the industry (Ip, 2025) ConfidentAI, (Labelbox, 2024) Labelbox. The practical effects of strong evaluation frameworks are demonstrated through case studies from healthcare implementations. Mount Sinai’s study showed 17-fold API cost reduction through task grouping, simultaneously processing up to 50 clinical tasks without accuracy loss. This demonstrates how thoughtful evaluation design can achieve both performance and efficiency goals in production environments (Ip, 2023) DevCommunity.

The technical advancement of Direct Preference Optimization (DPO) eliminates the requirement for explicit reward model training. The classification approach of DPO transforms RLHF into a classification task which results in training speedups of 2-3 times without compromising quality scores. The DPO system reaches 7.5/10 performance on MT-Bench while RLHF reaches 7.3/10 and achieves an 85% win rate on AlpacaEval compared to 82% for traditional RLHF while reducing training time from 36 hours to 12 hours for equivalent performance (SuperAnnotate, 2024) SuperAnnotate, (Werra, 2024) HuggingFace, (Wolfe, 2024) Substack.

7 Alternative Approach:

Constitutional AI, developed by Anthropic, offers an alternative approach that reduces human annotation requirements by 80-90% while maintaining comparable performance. The framework uses AI feedback rather than human labels through a dual-phase process: supervised learning with self-critique and revision, followed by reinforcement learning from AI feedback (RLAIF). This approach achieves 90%+ reduction in harmful outputs while maintaining 95%+ task performance, demonstrating that AI systems can learn to align with human values through structured self-improvement (Anthropic, 2022) Anthropic.

8 Challenges and Future Directions

8.1 Challenges:

  • Scalability: The process of gathering large amounts of human feedback proves both expensive and time-consuming. The expense of human evaluation spans between $50 and $200 per hour for expert reviewers which makes extensive assessment unaffordable for numerous organizations. The process of quality human evaluation depends on domain expertise and consistent training and ongoing calibration which increases the complexity and cost of evaluation processes. The agreement between different annotators shows wide variation because task complexity affects their correlation coefficients which range between 0.4 and 0.8 (10Pearls, n.d.) 10Pearls, (Dilmegani, 2025) AIMultiple.
  • Bias and Variability: Human evaluators bring both inconsistent results and personal prejudices to the evaluation process. Research indicates that 91% of LLMs learn from web-scraped data which contains underrepresentation of women in 41% of professional contexts and these biases continue to spread through evaluation systems. The evaluation methodology creates bias through order effects and length preferences and demographic assumptions and cultural perspectives which need systematic mitigation strategies that many organizations lack the necessary resources to implement effectively (Rossi et al., 2024) MITPress, (Barrow et al., 2023) Cornell.
  • The absence of ground truth in open-ended generation: The absence of ground truth for open-ended generation tasks makes ”correctness” inherently subjective and context-dependent, creating evaluation scenarios where multiple valid responses exist without clear ranking criteria. This ambiguity particularly affects creative tasks, conversational AI, and domain-specific applications where expertise requirements exceed general evaluation capabilities (Huang et al., 2023) Cornell.
  • Challenges with the integration of automated and human evaluation: Organizations need to perform extensive calibration to determine proper thresholds for human review triggers of automated systems while they need established protocols to resolve conflicts between automated and human evaluation results. The practical implementation of evaluation workflows faces ongoing challenges because of the difficulty in creating unified systems that integrate different approaches with quality standards.

9 Future Directions:

  • The implementation of active learning methods will help decrease the requirement for human evaluation.
  • The use of secondary AI models trained on human feedback data enables the automation of qualitative evaluations that mimic human assessments.
  • The future of evaluation methodology will depend on context-sensitive methods which modify assessment criteria according to task requirements and user needs and application domains. These methods aim to solve the current problem of standardized evaluation frameworks that fail to detect the wide range of LLM applications.
  • The development of unified evaluation approaches that can assess cross-modal consistency and coherence will become increasingly important as LLMs integrate with other AI systems to create more capable and versatile applications.
  • The Agentic evaluation frameworks need to assess both response quality and decision-making processes and safety implications and alignment with intended objectives (Andrenacci, 2025) Medium, (Chaudhary, 2025) Turing.
  • Real time evaluation systems need to maintain both thorough assessment capabilities and efficient computational performance.

10 Conclusion

The evaluation of LLMs through human feedback integration with automated metrics creates a complete assessment method for model effectiveness. The combination of traditional metrics with human judgment about quality produces better results for real-world applications and ethical compliance and user satisfaction. The implementation of holistic evaluation methods will produce more precise and ethical AI solutions which will drive future advancements. Multiple assessment methodologies should be used in successful evaluation frameworks to achieve a balance between automated efficiency and human reviewer judgment. Organizations that implement comprehensive evaluation strategies report substantial improvements in safety, performance, and operational efficiency, demonstrating the practical value of investment in robust evaluation capabilities.
