Summary
In this chapter, we have summarized the previous chapters in the book, reviewed some areas where NLU technology still faces challenges, and talked about some directions where it could improve in the future. NLU is an extremely dynamic and fast-moving field, and it will clearly continue to develop in many exciting directions. With this book, you have received foundational information about NLU that will enable you to decide not only how to build NLU systems for your current applications but also to take advantage of technological advances as NLU continues to evolve. I hope you will be able to build on the information in this book to create innovative and useful applications that use NLU to solve future practical as well as scientific problems.
