Python & NLP

Learn how to write programs that analyze written language.

The course will balance theoretical foundations with practical examples using the Python programming language.

No prior experience with libraries such as NLTK or scikit-learn is required for this course.

Audience:

Having existing experience with Python will be extremely beneficial but not required: users of other programming languages and tools (including e.g. Java, C++, C#, JavaScript, Matlab, Excel or Rlang) will find this course beneficial.

Course Outline:

1 - Foundations

This first section provides the basic tools and techniques to get started with Natural Language Processing

Overview on NLP applications and the Python

  • NLTK
  • spaCy
  • Gensim
  • scikit-learn

Working with text

  • Tokenisation
  • Text pre-processing
  • Regular Expressions

Word frequencies and co-occurrences

  • Stop-words and Zipf's Law
  • Mining topics of interest with co-occurrences

Text Representation

  • n-grams
  • Bag-of-words
  • Word embeddings and document embeddings

2 - Topic Modelling

This section aims at improving our understanding of a document, or a collection of documents, using techniques that go beyond simple word frequencies.

Topic Modelling

  • Bird's-eye view on a document or a dataset
  • Navigating topics and sub-topics in a document or a dataset

3 - Text Classification

This section tackles the problem of classifying documents into a set of predefined categories.

  • Categorising documents
  • Topic Classification
  • Sentiment Analysis
  • Model evaluation: assessing classification quality
  • Model introspection: explaining the classification results

4 - Overview on Advanced Applications

The last section offers an outlook on advanced NLP problems, so delegates are equipped with ideas and techniques to tackle more specific applications

Named Entity Recognition

  • Identifying named entity in text

Text Summarisation

  • Extracting the most useful sentences from a document or a collection of documents
