Analysis Framework

Initial Scan

Identify paper structure:

• Abstract and key claims
• Section organization (IMRaD vs custom)
• Figures and tables overview
• Reference density and key citations

Classify paper type:

• Theory: Proofs, mathematical foundations, formal results
• Methods: New algorithms, techniques, computational approaches
• Application: Domain-specific use cases, case studies
• Review: Surveys, systematic reviews, meta-analyses
• Empirical: Experimental results, observations, measurements

Content Extraction Priorities

Must extract:

1. Main contribution(s) and claims
2. Methodological approach and assumptions
3. Key results with statistical evidence
4. Limitations acknowledged
5. Related work positioning

Important to capture:

• Experimental setup and validation
• Implementation details
• Performance metrics and comparisons
• Dataset characteristics
• Reproducibility information

Nice to have:

• Future work suggestions

• Alternative approaches considered
• Failure modes discussed

Quality Assessment Criteria

Methodological Rigour

Strong indicators:

• Clear research questions

• Controlled comparisons
• Statistical significance properly assessed
• Limitations openly discussed
• Assumptions explicitly stated

Weak indicators:

• Vague objectives
• Methodology not justified
• Cherry-picked results
• Over-claiming based on limited evidence
• Ignoring contrary evidence
• Unacknowledged assumptions

Reproducibility Assessment

High reproducibility:

• Code publicly available
• Data accessible or well-described
• Implementation details complete
• Hyperparameters specified
• Random seeds provided
• Environment documented

Low reproducibility:

• "Implementation details omitted for brevity"
• No code or data shared
• Vague parameter descriptions
• Critical details missing
• Non-standard methods without explanation

Impact Potential

High impact indicators:

• Addresses important problem
• Novel approach or insight
• Strong empirical results
• Generalizable beyond specific case
• Clear practical applications
• Challenges existing assumptions

Limited impact indicators:

• Incremental improvement
• Narrow applicability
• Limited novelty
• Weak empirical support
• Unclear practical value

Analysis Structure

Overview Section

Synthesize (2-3 paragraphs):

• What problem does this address?
• What's the main contribution?
• What's the key finding or result?
• Why does this matter?

Highlights (Bullet Points)

Extract:

• Most important findings
• Key methodological innovations
• Surprising or counter-intuitive results
• Practical implications

Strengths Assessment

Methodological strengths:

• Rigorous experimental design
• Appropriate statistical analysis
• Comprehensive evaluation
• Clear presentation

Impact strengths:

• Novel contributions
• Practical applicability
• Theoretical insights
• Reproducibility support

Weaknesses Assessment

Be specific and fair:

• Methodological limitations
• Scope constraints
• Unclear explanations
• Missing comparisons
• Reproducibility concerns
• Over-claims not supported by evidence

Distinguish:

• Fundamental flaws (invalidate conclusions)
• Important limitations (affect interpretation)
• Minor issues (don't affect main findings)

Section-by-Section Analysis

• Is description complete enough to reproduce?
• Are limitations acknowledged?

Results/Experiments

Extract:

• Experimental setup

• Main findings with numbers
• Statistical significance
• Comparison with baselines

Assess:

• Are experiments well-designed?
• Are comparisons fair?
• Are results presented clearly?
• Is statistical analysis appropriate?
• Are claims supported by evidence?

Discussion/Conclusion

Extract:

• Interpretation of results
