Research Interests

Narrative Schemas
My research focuses on learning rich event structures called narrative schemas. Narrative schemas represent event relations, their participants, and semantic roles of the arguments. It is not dissimilar from Schankian scripts or common sense sequences of situations and events. My work is the first to utilize coreference and entity chains to learn a new type of relation based on narrative/discourse coherence.

Temporal Relations
I have several published papers on learning to temporally order events described in text. My supervised learning approaches learn from labelled corpora and I have transferred orderings to order the events in narrative schemas.

Dialogue
Before coming to Stanford, I published several pieces of work on language generation, dialogue, ontologies, and the semantic interpretation of web objects.

WeTheTeachers .com

I created a website in 2005 that encourages teacher collaboration and sharing of resources.
The site was sold to VIP Tone, Inc. in 2008.

School Boards

I created a campaign website: www.chambersforgv.com. My father, Bruce Chambers, is running for the school board in my old high school's district. He continually encouraged and supported me all the way to Stanford...hopefully the Great Valley community recognizes his talents. He's questioned their status quo, and is now being attacked for having the gumption to ask those questions. I credit him with motivating me to pursue my education this far, he loves students, and is honest in everything he does.

Brian Regan and Script Learning

[Observation]	People that play whole game get a whole snowcone.
[Observation]	And people that play half game get a whole snowcone.
[Conclusion]	So it's always whole, always whole snowcone.
[Goal]	So I'd rather play half game.
[Inference]	I'd rather play half game...still get the whole snowcone.
