Text Classification & Chatbots 2019


Notes:

In general, automatic text classification plays a vital role in text summarization, question answering and information extraction.  Automatic text classification is usually done by using a prelabeled training set and applying various machine learning methods such as naive Bayes, support vector machines, artificial neural networks, or hybrid approaches that combine various machine learning methods to improve the efficiency of classification.

  • Automatic text classification
  • Term selection
  • Text categorization
  • Text classifier
