Natural language processing more than 60 years of development process, basically can be divided into two stages. The early more than 20 years, from the the 1950s to the 70 's, is the stage for scientists to detour. Limitation: Simulating the human brain with a computer. Until the 1970s, methods based on mathematical models and statistics w
