  1. Foundations of Information Verification

    3 weeks
    Goals
    • Understand core principles of fact-checking methodology and source evaluation
    • Learn how LLMs generate text and why they hallucinate facts
    • Set up a Python development environment for AI-assisted workflows
    Resources
    • Google News Initiative - Verification Toolkit
    • OpenAI Cookbook - Introduction to LLM hallucinations
    • Coursera - Python for Everybody (Dr. Charles Severance)
    • Full Fact - The Fact Checker's Toolbox
    Milestone

    You can independently fact-check a 500-word AI-generated article using manual methods and explain why each error occurs from a model architecture perspective.

  2. Claim Extraction and NLP Pipelines

    4 weeks
    Goals
    • Build automated claim extraction pipelines using HuggingFace NER and relation extraction models
    • Implement structured claim decomposition (subject, predicate, object, qualifiers)
    • Use OpenAI function calling to output claims in structured JSON format
    Resources
    • HuggingFace NLP Course (huggingface.co/learn/nlp-course)
    • AllenAI SciFact dataset and paper for claim verification benchmarks
    • OpenAI Structured Outputs documentation
    • spaCy NER and dependency parsing tutorials
    Milestone

    You can build a pipeline that ingests raw AI text, extracts 10-50 discrete claims, and classifies each by claim type and verifiability.

  3. RAG-Based Evidence Retrieval

    5 weeks
    Goals
    • Design and implement retrieval-augmented verification systems using LangChain and LlamaIndex
    • Build vector stores over curated, trusted knowledge corpora
    • Implement chain-of-verification prompting to systematically check claims against retrieved evidence
    Resources
    • LangChain documentation - Retrieval and RAG modules
    • LlamaIndex documentation - Building knowledge agents
    • Pinecone learning center - Vector search fundamentals
    • Paper: 'Chain-of-Verification Reduces Hallucination in LLMs' (Meta AI)
    Milestone

    You can deploy an end-to-end RAG verification system that takes AI-generated content, retrieves evidence from a curated corpus, and produces a veracity score per claim.

  4. Advanced Verification and Adversarial Testing

    4 weeks
    Goals
    • Learn entailment-based verification using NLI models (e.g., DeBERTa-v3 on MultiNLI)
    • Perform adversarial red-teaming to discover systematic hallucination patterns
    • Build annotation workflows and measure inter-annotator agreement for verification labels
    Resources
    • HuggingFace - Textual Entailment models and benchmarks
    • Anthropic's red-teaming guide and OpenAI's red-teaming network documentation
    • CrowdTruth framework for annotation quality
    • Paper: 'TruthfulQA: Measuring How Models Mimic Human Falsehoods'
    Milestone

    You can adversarially probe any major LLM, catalog its domain-specific failure modes, and produce a calibration report with confidence intervals.

  5. Production Systems and Compliance Integration

    4 weeks
    Goals
    • Integrate verification pipelines into production content workflows with CI/CD patterns
    • Build dashboards and alerting for real-time monitoring of AI content accuracy
    • Map verification workflows to regulatory requirements (EU AI Act, FTC guidelines)
    Resources
    • AWS Bedrock Guardrails documentation
    • EU AI Act transparency and accuracy provisions summary
    • GitHub Actions for automated pipeline deployment
    • Weights & Biases - Experiment tracking best practices
    Milestone

    You can architect a production-grade verification system that runs continuously, integrates with content management systems, and produces audit-ready compliance reports.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

AI Article Fact-Checker CLI Tool

Beginner

Build a Python command-line tool that takes a plain-text AI-generated article, extracts factual claims using OpenAI's API, and outputs a structured JSON report with each claim, its category, and a preliminary veracity assessment.

~15h
Claim extraction and decompositionOpenAI API integrationStructured output parsing

RAG-Based Knowledge Verification Pipeline

Intermediate

Design and implement a LangChain-powered RAG pipeline that indexes a curated corpus of verified facts (e.g., Wikipedia curated subset, government statistics databases) and uses retrieval plus NLI to score the veracity of input claims.

~35h
RAG architecture designVector database managementNLI model fine-tuning and inference

Hallucination Pattern Catalog for a Specific LLM

Intermediate

Systematically probe a chosen LLM (e.g., Llama 3 70B) across 5 defined domains, catalog the types and frequency of hallucinations, and publish a structured report with examples, patterns, and risk scores. Include a reproducible test harness.

~30h
Adversarial prompt designSystematic evaluation methodologyStatistical analysis of model outputs

Real-Time Verification Dashboard

Advanced

Build a web-based dashboard that connects to a live AI content generation pipeline, performs automated claim extraction and verification in near-real-time, and displays verification status, confidence scores, and flagged items for human review. Use Streamlit or Next.js for the frontend, with a Python/FastAPI backend.

~60h
Full-stack verification system architectureReal-time data processingAPI design and integration

Multi-Language Claim Verification Agent

Advanced

Build a LangChain-based agent that can verify factual claims in at least 3 languages by leveraging cross-lingual NLI models, multilingual knowledge bases, and translation-aware evidence retrieval. Include evaluation benchmarks comparing accuracy across languages.

~50h
Multilingual NLP processingCross-lingual NLI model deploymentAgent architecture with tool use
