Better Data for NLP

Modern natural language processing is not only about the models, but also about the data. The decisions we make in collecting, curating, pre-processing, and annotating data have significant effect on the final systems, and we have a long way to go.

The projects in this area are concerned broadly with issues in collecting data that is used for training NLP models, and creating benchmarks that can reliably estimate their capabilities. This such aspects of data collection as sampling, representativeness, and annotation practices.

 

 

The wave of deep learning in NLP came together with increasing popularity of large crowdsourced datasets, but the limitations of this approach are becoming increasingly clear.

- an ongoing project in collaboration with University of Massachusetts, dedicated to development of resources for temporal relation extraction.

It is increasingly clear that while the current deep learning systems can solve any supervised learning NLP task that researchers have so far come up with, this is done without any real verbal reasoning. To make progress, the field needs to re-evaluate the role of resource development methodology, and provide clearer definitions for its tasks.
