Executive Development Programme in Python NLP: Creating a Custom Text Preprocessing Pipeline

This course is designed for executives and business leaders with a basic understanding of Python who wish to enhance their data processing skills for natural language processing (NLP). Participants will gain the ability to create a custom text preprocessing pipeline, including text cleaning, tokenization, and feature extraction, essential for effective NLP applications in business analytics.

By the end of the course, attendees will be able to implement these techniques to preprocess textual data, improving the accuracy of NLP models used for tasks such as sentiment analysis, text classification, and customer support chatbot responses, thereby driving more informed business decisions.

1. 1. Introduction to Python for NLP: Learners will study the basics of Python programming and how it is used in natural language processing. They will gain practical skills in setting up a Python environment, using libraries like NLTK and spaCy, and writing basic NLP scripts.
2. 2. Text Basics and Data Cleaning: Learners will explore foundational concepts of text data, including text formats, encoding, and data cleaning techniques. They will learn how to clean, preprocess, and normalize text data to prepare it for NLP tasks.
3. 3. Tokenization and Segmentation: This module covers advanced techniques for breaking down text into meaningful units such as words, sentences, and paragraphs. Learners will gain skills in using tokenizers and segmentation tools to handle different languages and text structures.
4. 4. Text Normalization and Stemming/Lemmatization: Learners will study various text normalization techniques, including stemming and lemmatization, to reduce words to their root forms. They will practice applying these techniques to improve the quality of text data for NLP models.
5. 5. Named Entity Recognition (NER): This module focuses on identifying and extracting named entities from text, such as people, organizations, and locations. Learners will learn how to use pre-trained models and develop custom NER pipelines using libraries like spaCy.
6. 6. Sentiment Analysis and Text Classification: Learners will delve into analyzing the sentiment of text and classifying text into predefined categories. They will gain skills in preparing datasets, training models, and evaluating the performance of sentiment analysis and text classification systems.
7. 7. Custom Text Preprocessing Pipeline Development: In this module, learners will design and implement a comprehensive text preprocessing pipeline, integrating various preprocessing steps learned in previous modules. They will apply best practices and optimize their pipelines for specific NLP tasks.
8. 8. Advanced Text Features and Representations: This module explores advanced techniques for representing text data, including word embeddings, n-grams, and contextual embeddings. Learners will understand how to extract meaningful features from text and apply them in NLP models.
9. 9. Customizing NLP Models for Domain-Specific Applications: Learners will learn how to adapt NLP models for specific domains, such as healthcare, finance, or social media. They will gain skills in collecting domain-specific data, fine-tuning models, and evaluating their performance for domain-specific tasks.
10. 10. Project: Building a Custom Text Preprocessing Pipeline: In the final module, learners will apply all the knowledge and skills gained throughout the programme to build a custom text preprocessing pipeline for a real-world NLP project. They will work on a comprehensive project to demonstrate their understanding and practical capabilities.
