Ontology Alignment in the Biomedical Domain Using Entity Definitions and Context

Lucy Lu Wang, Chandra Bhagavatula, Mark Neumann +3

Ontology alignment is the task of identifying semantically equivalent entities from two given ontologies. Different ontologies have different representations of the same entity, re…

Citation Count Analysis for Papers with Preprints

Sergey Feldman, Kyle Lo, Waleed Ammar

We explore the degree to which papers prepublished on arXiv garner more citations, in an attempt to paint a sharper picture of fairness issues related to prepublishing. A paper's c…

Content-Based Citation Recommendation

Chandra Bhagavatula, Sergey Feldman, Russell Power +1

We present a content-based method for recommending citations in an academic paper draft. We embed a given query document into a vector space, then use its nearest neighbors as cand…

Ontology-Aware Token Embeddings for Prepositional Phrase Attachment

Pradeep Dasigi, Waleed Ammar, Chris Dyer +1

Type-level word embeddings use the same set of parameters to represent all instances of a word regardless of its context, ignoring the inherent lexical ambiguity in language. Inste…

Semi-supervised sequence tagging with bidirectional language models

Matthew E. Peters, Waleed Ammar, Chandra Bhagavatula +1

Pre-trained word embeddings learned from unlabeled text have become a standard component of neural network architectures for NLP tasks. However, in most cases, the recurrent networ…
