    Watson Natural Language Classifier (NLC) allows users to classify text into custom categories, at scale. Developers without a background in machine learning (ML) or NLP can enhance their applications using this service. NLC combines various advanced ML techniques to provide the highest accuracy possible, without requiring a lot of training data

    step 7:train the natural language processing classifiers

    The Natural Language Processor automatically infers which classifiers need to be trained based on the directory structure and the annotations in the training data. In our case, the NLP will train an intent classifier for the store_info domain and entity recognizers for each intent that contains labeled queries with entity annotations. Domain classification and role classification models will not be built because …

    The first step towards training a machine learning NLP classifier is feature extraction: a method is used to transform each text into a numerical representation in the form of a vector. One of the most frequently used approaches is bag of words , where a vector represents the frequency of a word in a predefined dictionary of words
