Explaining Answers with Entailment Trees

1 code implementation EMNLP 2021 Bhavana Dalvi, Peter Jansen, Oyvind Tafjord, Zhengnan Xie, Hannah Smith, Leighanna Pipatanangkura, Peter Clark

Our approach is to generate explanations in the form of entailment trees, namely a tree of multipremise entailment steps from facts that are known, through intermediate conclusions, to the hypothesis of interest (namely the question + answer).

Pretrained Language Models for Sequential Sentence Classification

1 code implementation IJCNLP 2019 Arman Cohan, Iz Beltagy, Daniel King, Bhavana Dalvi, Daniel S. Weld

As a step toward better document-level understanding, we explore classification of a sequence of sentences into their corresponding categories, a task that requires understanding sentences in context of the document.

A Dataset of Peer Reviews (PeerRead): Collection, Insights and NLP Applications

1 code implementation NAACL 2018 Dongyeop Kang, Waleed Ammar, Bhavana Dalvi, Madeleine van Zuylen, Sebastian Kohlmeier, Eduard Hovy, Roy Schwartz

In the first task, we show that simple models can predict whether a paper is accepted with up to 21% error reduction compared to the majority baseline.

What Happened? Leveraging VerbNet to Predict the Effects of Actions in Procedural Text

no code implementations15 Apr 2018 Peter Clark, Bhavana Dalvi, Niket Tandon

To supply this knowledge, we leverage VerbNet to build a rulebase (called the Semantic Lexicon) of the preconditions and effects of actions, and use it along with commonsense knowledge of persistence to answer questions about change.

Exploratory Learning

no code implementations1 Jul 2013 Bhavana Dalvi, William W. Cohen, Jamie Callan

In multiclass semi-supervised learning (SSL), it is sometimes the case that the number of classes present in the data is not known, and hence no labeled examples are provided for some classes.

no code implementations1 Jul 2013 Bhavana Dalvi, William W. Cohen, Jamie Callan

We describe a open-domain information extraction method for extracting concept-instance pairs from an HTML corpus.
