WP 1: Lexicon, Syntax, Semantics: Structured Prediction and Domain Adaptation (WS 2017-2018)

Summary

Structured prediction is typically solved using classifiers which predict an output with structure, often by making several classification decisions which are dependent on one another. Examples of structured prediction problems include language modeling and machine translation (where the words in the output depend on one another) and syntactic problems such as POS-tagging or syntactic parsing (where the classification labels chosen depend on one another).

Domain adaptation is, broadly speaking, the problem of training a classifier using one distribution and testing it on another distribution. There are many examples of this in real-world applications of natural language processing. One example is that a machine translation system may be trained on government proceedings (such as the Proceedings of the European Parliament) but then applied to translating medical documents. Another examples is that a syntactic parser may be trained on news articles, but applied to predicting the syntactic structure of sentences in tweets.

Content:

The seminar will discuss these two interesting problems and their intersection, by looking at state-of-the-art research papers. Most of the papers discussed will involve deep learning approaches applied to problems of structured prediction, but familiarity with older classification approaches (e.g., using linear models) will be useful.

Goals:

The goal of the seminar is to understand the basics of structured prediction, domain adaptation, and domain adaptation techniques applied to structured prediction. A secondary goal is to acquire a broad picture of the state-of-the-art in these problems, particularly as applied in natural language processing.
