The aim of this project is to develop new unsupervised computational models to automatically extract background knowledge after reading large amounts of unstructured text.
This semantic knowledge will then be integrated with structured relational databases
using graph algorithms.
The result of these innovations will enable computers to make
better-informed summaries and semantic searches.
Previously I have worked on
natural language summarization using integer linear programming (ILP).
I developed novel models for text generation, tasks such as producing summaries, highlights, captions or simplifications of existing articles.
My PhD was in large-scale numerical optimization, under the supervision of
Prof Jacek Gondzio at
I researched methods for training support vector machines (SVM) using the interior point method of continuous optimization.
The techniques I developed were particularly efficient on multicore parallel computing platforms, and the software did pretty well in the
Pascal Large Scale Learning Challenge (2008).
You can download the software — it is free for academic use.
Here are data sets and other material we have used in papers:
- CNN highlights dataset used in Woodsend and Lapata (2010, ACL); contains alignments of CNN highlights with document sentences.
- Simple English Wikipedia revisions dataset used in Woodsend and Lapata (2011, EMNLP); this contains diff-ed revisions of Simple English Wikipedia that were marked by the editors as simplifications.
