Cognitive Computing (CC) is a cutting-edge paradigm of intelligent computing methodologies and systems based on cognitive informatics, which implements computational intelligence by autonomous inferences and perceptions mimicking the mechanisms of the brain. Cognitive computing systems are the application of computing power to penetrate and analyze the complexity of Big Data in hopes of solving so-called soft problems—that is, problems that are layered and ambiguous in nature. These problems are usually ambiguous and uncertain with ever-changing sets of data and, most importantly, with no singularly correct answer.
