Cognitive Computing with IBM Watson

By: Rob High, Tanmay Bakshi

Overview of this book

Cognitive computing is rapidly becoming a part of every aspect of our lives through data science, machine learning (ML), and artificial intelligence (AI). It allows computing systems to learn and keep on improving as the amount of data in the system increases. This book introduces you to a whole new paradigm of computing – a paradigm that is totally different from the conventional computing of the Information Age. You will learn the concepts of ML, deep learning (DL), neural networks, and AI with the help of IBM Watson APIs. This book will help you build your own applications to understand, and solve problems, and analyze them as per your needs. You will explore various domains of cognitive computing, such as NLP, voice processing, computer vision, emotion analytics, and conversational systems. Equipped with the knowledge of machine learning concepts, how computers do their magic, and the applications of these concepts, you’ll be able to research and apply cognitive computing in your projects.

Identifying entities through annotators

Let's return to the first style of identifying an entity that you care about. In the first approach, we showed you in Recognizing entities, we went to the intent examples, and highlighted the entity that we cared about in that example. We refer to this as the annotator approach to entity recognition. Annotators are a much more powerful way of identifying the entities. Rather than setting a rule, such as the word hot is a temperature entity, the annotator approach builds a machine learning algorithm that takes in the context of the surrounding words in the sentence. In doing so, it calculates the probability that hot is referring to a temperature. In a sentence such as The water is hot, it makes sense to recognize hot as being a temperature. But in another sentence, such as The market is hot, it should be taken to be the relative value people place on a particular product.

As your conversational agent gets more sophisticated, you will likely want to...
