Effective leverage of AI and machine learning requires the intersection of domain knowledge and AI skills. This workshop on natural language processing (NLP) covers key approaches for making sense of text data. The aim of the workshop will be to help finance professionals understand how to frame and think through NLP problems. This will enable them to work effectively with data science teams to create NLP solutions that will benefit investment decisions. A range of approaches will be discussed including: A general overview to NLP text-mining problems, Data pre-processing, Machine Learning Models, Feature Selection, and Testing. Example implementation examples will be shown. Also, there will be practical sessions where we work through the steps needed to build an NLP solution.
