Text Chunking Using Transformation-Based Learning
Lance Ramshaw,Mitchell Marcus +1 more
TL;DR: This work has shown that the transformation-based learning approach can be applied at a higher level of textual interpretation for locating chunks in the tagged text, including non-recursive “baseNP” chunks.

Text Chunking using Transformation-Based Learning
Lance Ramshaw,Mitchell Marcus +1 more
TL;DR: The authors used transformation-based learning for part-of-speech tagging with fairly high accuracy, achieving recall and precision rates of roughly 92% for base NP chunks and 88% for more complex chunks.

OntoNotes: The 90% Solution
TL;DR: It is described the OntoNotes methodology and its result, a large multilingual richly-annotated corpus constructed at 90% interannotator agreement, which will be made available to the community during 2007.

CoNLL-2011 Shared Task: Modeling Unrestricted Coreference in OntoNotes
TL;DR: The CoNLL-2011 shared task involved predicting coreference using OntoNotes data, a new resource that provides multiple integrated annotation layers (parses, semantic roles, word senses, named entities and coreference) that could support joint models.
Proceedings Article
A novel use of statistical parsing to extract information from text
TL;DR: A lexicalized, probabilistic context-free parser is adapted to information extraction and this new technique is evaluated on MUC-7 template elements and template relations.
