Watson

Watson is a question-answering computer system capable of answering questions posed in natural language, developed in IBM's DeepQA project by a research team led by principal investigator David Ferrucci. Watson was named after IBM's founder and first CEO, industrialist Thomas J. Watson.

History

The computer system was initially developed to answer questions on the quiz show Jeopardy!. In 2011, Watson competed on Jeopardy! against former winners Brad Rutter and Ken Jennings. Watson received the first place prize of $1 million.

Design

Watson's basic working principle is to parse keywords in a clue while searching for related terms as responses. This involves a number of algorithms, including algorithms for parsing, algorithms for search, and algorithms for scoring answers.

Applications

Since its Jeopardy! win, Watson has been applied to a number of applications. It has been used in healthcare, to help clinicians identify treatment options for cancer patients. Watson for Oncology has an advanced ability to analyze the meaning and context of structured and unstructured data in clinical notes and reports that may be critical to selecting a treatment pathway.
