What is Cognitive Computing?
The term cognitive computing refers to new hardware and/or software that mimics the functioning of the human brain and helps to improve the human decision-making process. Cognitive computing in a broader sense describes technology platforms that are based on the scientific disciplines of artificial intelligence, signal and image processing. These platforms encompass machine learning, reasoning, natural language processing, speech recognition and vision (object recognition), the human-computer interaction, among other technologies to perform specific, human-like tasks in an intelligent way.
Optical Character Recognition (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image . It is widely used as a form of information entry from printed paper data records, whether passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation. It is a common method of digitizing printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as cognitive computing, machine translation, (extracted) text-to-speech, key data and text mining. OCR is a field of research in pattern recognition, artificial intelligence, and computer vision.
