Chief Scientist for Natural Language Processing at Didi Global.

Research interests include: artificial intelligence, natural language processing, machine translation, dialog processing, automata theory, decipherment.

Now hiring at DiDi Labs in Los Angeles!

Prior to joining DiDi, I spent many years working as a professor in the Department of Computer Science of the University of Southern California.

Chief Scientist, Specifio.

My publications. My vita.

Let's solve the 3n+1 problem!

We recently organized a Russian/Chinese common MT evaluation.

If you don't want to read this whole page, here's a quick summary.

We made a nice site about Chinese NLP!

Cryptography consultant, Under the Silver Lake (2019).

Co-inventor on a 2019 US patent about software that writes patents, written by software that writes patents.

Co-organized IWSLT 2020, co-Program Chair of First Asia-Pacific ACL 2020, co-Program Chair of CCMT 2019 (China Conference on Machine Translation), co-General Chair of CCF-ICAI 2019 (CCF International Conference on Artificial Intelligence).

You're wondering why I got fried?

Say what? Don't let him cash you outside.

I put together a long-running natural language seminar. Here are the guidelines.

If I could change my profession, I would like to try naval attaché.

My busy robot. Hush, puppy.

Master of Chaos? Except I don't wear rouge.

We built an AMR semantics bank. It's like a treebank, but for semantics.

The Copiale cipher.

Here's a bunch of ISI NLP software.

Listen to the rhythmic news gabbler from me and Marjan. We have thousands of hours!

I think our approach to syntax in machine translation is best described in D. Barthelme's short story They called for more structure....

I am literally begging you to do more random restarts.

The outside of my laptop.

Check out these slides from my ACL 2013 Decipherment Tutorial.

I was asked to run for a position in my professional association. A bogus platform somehow circulated, which I completely repudiated. Once elected, though, I felt strangely compelled to implement it.

Led Zeppelin! Tangerine guitar solo!

I recently said this out loud: "I want a four-door convertible like the one Lincoln was assassinated in."

The best grade I ever got was "better than expected".

I have been fortunate to work with great students.
PhD graduates include:
**Nima Pourdamghani** (thesis on low-resource MT),
**Xing Shi** (thesis on recurrent networks),
**Marjan Ghazvininejad** (thesis on creative language generation),
**Qing Dou** (thesis on decipherment),
**Steve DeNeefe** (thesis on adjoining for MT),
**Sujith Ravi** (thesis on decipherment),
**Jonathan May** (thesis on tree automata for NLP),
**Yaser Al-Onaizan** (thesis on named-entity translation),
**Kenji Yamada** (thesis on syntax-based MT),
**Irene Langkilde-Geary** (thesis on language generation),
**Philipp Koehn** (thesis on noun phrase translation), and
**Ishwar Chander** (thesis on statistical article generation).
I co-advised PhD theses from **Victoria Fossum**,
**Shou-de Lin** and **Liang Huang**,
and I supervised two Masters theses: **Bryant Huang**'s
on syntax-structuring for translation, and
**Nada Aldarrab**'s
thesis on decipherment.

I recently went to Denmark. Here's me in Denmark.

Here's a story called Little House on the West Bank. No matter how readers interpret the text, my favorite part is still where the baby throws up on the mom. And here's a gruesome fairy tale for you.

Here is a slide show that explains the global situation to American people.

I'm possibly the least-skilled person at drawing ever to get paid for it, for example: actual conversations ... strange things ... parking structures ... werld maps. Some fortune-telling cards.

A machine translation glossary for those in the field.

I wrote a book for little kids, and another book for big kids.

I used to be an Amber freak, a long time ago, and kept myself amused. Since then, five of my favorite writers are Philip K. Dick, Jack Womack, Jim Thompson, George Saunders, and Haruki Murakami. I've read Thompson's Pop 1280 quite a few times -- that is a god-danged good book. Other favorites: A Scanner Darkly, Man in the High Castle, Confessions of a Crap Artist, Puttering about in a Small Land, Now Wait for Last Year, The Penultimate Truth, Ambient, Terraplane, Heathern, Elvissey, Random Acts of Senseless Violence, and Let's Put the Future Behind Us. I like also Don Delillo, David Lodge, Kurt Vonnegut, and J. D. Salinger. Seems like the first couple of books are always better than all the rest. I like Bob Dylan's music and found his autobiography (Chronicles, Vol. 1) strangely similar Neil Armstrong's biography (First Man). Other books: Tao Te Ching, and Benjamin Tucker's Instead of a Book. I think Gary Shteyngart is funny.

My Dan Klein number is 1.
