Watson is an IBM supercomputer that combines artificial intelligence (AI) and sophisticated analytical software for optimal performance as a “question answering” machine. The supercomputer is named for IBM’s founder, Thomas J. Watson.

Applications for the Watson's underlying cognitive computing technology are almost endless. Because the device can perform text mining and complex analytics on huge volumes of unstructured data, it can support a search engine or an expert system with capabilities far superior to any previously.

IBM WATSON is a cognitive system that allows developer to cooperate cognitive and machine learning to their applications without having the coding actual intelligence. The computer system was initially developed to answer questions on the quiz show. IBM announced that Watson software system's first commercial application would be for utilization management decisions in lung cancer treatment. 11 operating system using the Apache Hadoop framework to provide distributed computing.

Watson combines five core capabilities:

• Interacts with people more naturally, based on the person’s preference.

• Quickly ingests key industry materials, partnering with experts to scale and elevate expertise.

• Enables new products and services to sense, reason and learn about their users and the world around them.

• Uses data to improve business processes and forecasting, increasing operational effectiveness.

• Enhances exploration and discovery, uncovering unique patterns, opportunities and actionable hypotheses.

IBM Watson is at the forefront of a new era of computing: cognitive computing. Watson can understand all forms of data, interact naturally with people, and learn and reason, at scale.

Cognitive computing is becoming a new industry. A new industrial revolution is coming, connected to job automation in transportation, customer care, and healthcare, to name a few. The livelihood of such a revolution will be a new generation of skilled developers who understand cognitive computing well enough to envision new business applications, and ultimately build the new cognitive web. The voice user interface is a great way to enhance the user interface of lot devices, robots, or a voice-controlled vehicle. IBM Watson Text-To-Speech service is available from the IBM BLUEMIX catalog.

IBM WATSON will change the coming future and this technology will help lot of developer to step up next level. Lets hope for better future with the help of IBM WATSON & Cognitive apps.
