Mission & Content Summary
MISSION

Natural Language Processing tools are becoming ubiquitous: from everyday tools like Siri or Alexa to decision making processes in industry or politics and to text analysis tools in social science research. Machine-learning based text analysis tools provide a range of possibilities and are a growing field of expertise. Whether it is the exploration of text to find structures and topics, or the construction of a classifier to predict the sentiment or author characterstics of a text, this course provides an overview and hands-on experience in all relevant techniques.

CONTENT SUMMARY

Preparation: how do I work with text:

  • Data formats.
  • Preprocessing.
  • Storage and retrieval.

 

Exploration: exploring structure in the data:

  • Clustering.
  • Topic models.
  • Word embeddings.

 

Prediction: finding patterns to impute new values:

  • Text classification (sentiment analysis, author attributes).
  • Logistic Regression.
  • Perceptron.
  • Feed-forward Neural Nets.
  • Convolutional Neural Nets.
  • Structured prediction (parts of speech, parsing, discourse).
  • Structured perceptron.
  • Recurent Neural Nets.

Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Describe different text analysis problems.
  • Talk about the linguistic foundations.
  • Distinguish between exploration and prediction approaches.
  • Know which algorithm to choose for a given problem.
  • Understand the trade-offs between different approaches.
APPLYING KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Apply their knowledge to a practical problem.
  • Implement a variety of algorithms for text exploration and classification in Python.
