  1. Foundations of Text & NLP

    6 weeks
    • Master Python for data manipulation and basic NLP tasks.
    • Understand core NLP concepts: tokenization, stemming, POS tagging.
    • Learn the theory behind named entity recognition.
    • Coursera: Natural Language Processing Specialization (deeplearning.ai)
    • Book: 'Natural Language Processing with Python' (NLTK)
    • Kaggle: Intro to NLP course
    Milestone

    Can clean text data and use spaCy/NLTK for basic entity extraction using rule-based and simple ML models.

  2. Deep Learning for NER

    8 weeks
    • Understand transformer architecture and attention mechanisms.
    • Learn to fine-tune BERT-family models for custom NER using HuggingFace.
    • Master evaluation metrics (F1-score, confusion matrix) for sequence labeling.
    • HuggingFace NLP Course (free)
    • Papers: 'BERT: Pre-training of Deep Bidirectional Transformers'
    • PyTorch/TensorFlow tutorials on sequence modeling
    Milestone

    Can prepare custom datasets, fine-tune a BERT model for NER, and rigorously evaluate its performance on a held-out test set.

  3. LLM Orchestration & Prompt Engineering

    6 weeks
    • Master advanced prompt engineering for entity extraction tasks.
    • Learn to build RAG (Retrieval-Augmented Generation) and agent pipelines with LangChain.
    • Integrate NER models into API-based applications.
    • LangChain documentation and tutorials
    • OpenAI API documentation
    • DeepLearning.AI: Building Systems with ChatGPT API
    Milestone

    Can design a multi-step LangChain pipeline that uses an LLM for entity extraction, validates the output, and feeds it to a downstream tool.

  4. Production Systems & CX Integration

    6 weeks
    • Learn MLOps basics: containerization (Docker), CI/CD for ML.
    • Understand real-time inference serving and monitoring.
    • Study key CX metrics (CSAT, CES) to align model output with business goals.
    • MLOps Zoomcamp (free)
    • FastAPI for creating model serving endpoints
    • Articles on model monitoring with Prometheus/Grafana
    Milestone

    Can deploy a fine-tuned NER model as a scalable, monitored API endpoint and articulate its impact on a customer experience metric.

Practice Projects

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

Customer Support Ticket Entity Extractor

Beginner

Build a system to extract key entities (order IDs, product names, issue types) from a dataset of customer support emails. Use spaCy or a pre-trained transformer model and evaluate performance.

Domain-Specific NER Fine-Tuning with HuggingFace

Intermediate

Fine-tune a BERT model on a niche dataset (e.g., biomedical abstracts, legal clauses) to recognize specialized entities. Focus on the end-to-end HuggingFace Trainer workflow.

LangChain-Powered Conversational Entity Agent

Advanced

Create an agent that uses an LLM via LangChain to extract entities from a user's conversational query, then uses a tool to fetch relevant information about those entities (e.g., product details from a mock API).

Real-Time NER Microservice with FastAPI & Monitoring

Advanced

Deploy a fine-tuned NER model as a REST API using FastAPI. Containerize it with Docker, and set up basic monitoring to log prediction confidence and latency.
