Hi all, Our final lecture, *Lecture 6: Language <https://cs50.harvard.edu/summer/ai/2020/lectures/6/>*, is now available on the course website. In this last unit of the course, we start to explore how AI can process and derive some understanding from human language. We'll explore strategies that AI can use for understanding sentence structure, classifying text, retrieving and extracting information out of documents, representing words numerically, and more. For the first part of this week's project, you'll build a context-free grammar for parsing sentences and extracting topics from those sentences. In the second part, you'll build a simple automated question answering system that can search a corpus of documents for answers to questions. A few other important announcements for this week: - Quiz 6 <https://cs50.harvard.edu/summer/ai/2020/quizzes/6/> is now available and is due by 11:59pm ET on Wed 8/5. As a reminder, each quiz is open-book: you may use any and all non-human resources during a quiz, but the only humans to whom you may turn for help or from whom you may receive help are the course’s heads. - Project 6 <https://cs50.harvard.edu/summer/ai/2020/projects/6/> is now available and is due by 11:59pm ET on *Fri 8/7*. (Note that, since the Summer School term ends after this week, the deadline is Friday rather than the usual Sunday.) - Our final *sections <https://cs50.harvard.edu/summer/ai/2020/sections/> *will be this week, and will be an opportunity to explore natural language processing more, see additional examples of lecture material, and ask questions about this week's concepts. You're encouraged to attend if you can! As always, feel free to reach out to me or any of the staff with any questions! All the best, Brian
