Speech and Language Processing (3rd ed. draft)
Dan Jurafsky and James H. Martin

Here's our September 21, 2021 draft! This is just an update draft, fixing bugs and filling in various missing sections (more on transformers, including for MT, various updated algorithms, like for dependency parsers, etc.). Expect another release later this fall with drafts of some of the 3 missing chapters.
We are really grateful to all of you for finding bugs and offering great suggestions!

Individual chapters are below; here is a single pdf of all the chapters in the Sep 21, 2021 draft of the book-so-far

As always, typos and comments very welcome (just email slp3edbugs@gmail.com and let us know the date on the draft)!
(Due to reorganizing, still expect some missing latex cross-references throughout the pdfs, don't bother reporting those missing ref/typos.)

Feel free to use the draft slides in your classes.

When will the whole book be finished?
Don't ask. But we're still shooting for before the end of 2021 for the 3 remaining chapters (Intro, Contextual Embeddings, Semantic Parsing) + random missing sections, but we'll see, and then the publishing process of course takes time.

And if you need last year's draft chapters, they are here.
