I am an Associate Professor in the Allen School of Computer Science & Engineering at the University of Washington. I also lead a soon-to-be-named project at the Allen Institute for Artificial Intelligence. Previously, I did postdoctoral research at the University of Edinburgh and was a Ph.D. student at MIT.

Research

My current research is in the intersections of natural language processing, machine learning, and decision making under uncertainty. I am particularly interested in designing learning algorithms for recovering representations of the meaning of natural language text. For more details, please see my publications.

Announcements

• Luheng released DeepSRL, an end-to-end neural SRL system that performs 4 F1 points better than any other publicly released PropBank model (a nearly 20% error reduction).
• Congratulations to Kenton and Mike for winning a best paper award for Global Neural CCG Parsing with Optimality Guarantees at EMNLP 2016!
• Mark released ImSitu, a large, new situation recognition dataset. He has formulated this recognition problem as visual semantic role labeling, where images are mapped to structured action representations. Have a look at the data and recognition demo!
• Luheng released a QA-SRL dataset, demonstrating that non-expert annotators can provide supervision for recovering the predicative argument structure of English sentences.
• Mike released EasySRL, a joint CCG and SRL parser that builds wide-coverage logical forms and uses a fast A* algorithm.
• Congratulations to Yoav and Kenton for winning a best paper award for Broad-coverage CCG Semantic Parsing with AMR at EMNLP 2015!
• Kenton released UW Time, a context-dependent semantic parser for detecting and resolving time expressions.
• Yoav is recording a tutorial on Semantic Parsing with CCG.
