WHAT IF<\/strong>
\nWhat if we could advance the capabilities of Natural Language Processing (NLP) by developing a parsed text database, or treebank, that was rich, flexible and dynamic?<\/p>\n

\"Rich<\/a><\/p>\n

WHAT WE SET OUT TO DO<\/strong>
\nWe set out to design and develop a dynamic parsed text database (or treebank) for collecting and analyzing natural language. Our goal was to allow linguistic data to be retrieved from the treebank in varying granularity, and to enable regular updates to the treebank so that it could evolve.<\/p>\n

WHAT WE FOUND<\/strong>
\nThe project, named LinGO Redwoods, built the foundations for this new type of treebank, including a set of software tools for annotation and dynamic updates, a database of hand-disambiguited analysis for 10,000 utterances and baseline results for a variety of parse selection models. The results of this seeding activity serve as a Proof of Concept for the proposed new methodology, enabling researchers to circulate the approach with a wider academic and industrial audience and expand the treebank.<\/p>\n

PEOPLE BEHIND THE PROJECT<\/strong>
\n\"Christopher<\/a>Christopher Manning<\/a><\/strong> is a Professor of Computer Science and Linguistics at Stanford University. His research goal is computers that can intelligently process, understand, and generate human language material. Manning is a leader in applying Deep Learning to Natural Language Processing, with well-known research on Tree Recursive Neural Networks, sentiment analysis, neural network dependency parsing, the GloVe model of word vectors, neural machine translation, and deep language understanding.<\/p>\n

\"Stephan<\/a>Stephan Oepen<\/a><\/strong>\u00a0is Professor in Computational Linguistics at the University of Oslo, where he heads the Division for Language Technology at the University of Oslo. Since 2000, he has also been a Senior Researcher at the Center for the Study of Language and Information, Stanford University. Stephan Oepen studied Linguistics, German and Russian Philology, Computer Science, and Computational Linguistics at Berlin, Volgograd, and Saarbr\u00fccken.<\/p>\n

\"Carl<\/a>Carl Vogel<\/a><\/strong> is Associate Professor in Computation Linguistics at Trinity College, University of Dublin, where he also serves as the Director of the Trinity Centre for Computing and Language Studies. His work in computational linguistics as a cognitive science frequently draws upon evidence abstracted from Internet accessed data, and accordingly he dwells on the accompanying research methodology issues.\u00a0Dr. Vogel contributes in areas of practical computation, representation of grammatical structures, and general HPSG theory (feature logic background, syntax \u2013 semantics interface).<\/p>\n","protected":false},"excerpt":{"rendered":"
