Developing Bots. Primers


During the workshop, we implement three different types of bots. We have prepared a few notebooks to be done before the course to the participants a short introduction into chatbots. We implement an HR assistant bot that can be a basis for your projects.

At the beginning of day on one of the courses we present bot taxonomy and machine learning terms related to bots. Next, we go through natural language processing and natural language understanding. During the training, we go also into more complex topics like sentiment analysis, context management and how to build intelligent bots. We show how to develop a vectorizer and build a sentiment analysis method. This method is next compared with other solutions that are available on the market. The context management is a complex topic and we show how to use some methods to deal with context recognition and management in case we have more than one.


Prerequisites

  • Basic Python knowledge,
  • Recommended: basic machine learning knowledge


Outcomes

Participants will understand…

  • how to use NLP methods,
  • how machine learning methods are used for bots,
  • generative and relative approaches to NLU,
