You can't pick your neighbors, or can you? When and how to rely on retrieval in the NN-LM

Andrew Drozdov, Shufan Wang, Razieh Rahimi +3

Retrieval-enhanced language models (LMs), which condition their predictions on text retrieved from large external datastores, have recently shown significant perplexity improvement…

Efficient Nearest Neighbor Search for Cross-Encoder Models using Matrix Factorization

Nishant Yadav, Nicholas Monath, Rico Angell +2

Efficient k-nearest neighbor search is a fundamental task, foundational for many problems in NLP. When the similarity is measured by dot-product between dual-encoder vectors or $\e…

Longtonotes: OntoNotes with Longer Coreference Chains

Kumar Shridhar, Nicholas Monath, Raghuveer Thirukovalluru +4

Ontonotes has served as the most important benchmark for coreference resolution. However, for ease of annotation, several long documents in Ontonotes were split into smaller parts.…

Multi-CLS BERT: An Efficient Alternative to Traditional Ensembling

Haw-Shiuan Chang, Ruei-Yao Sun, Kathryn Ricci +1

Ensembling BERT models often significantly improves accuracy, but at the cost of significantly more computation and memory footprint. In this work, we propose Multi-CLS BERT, a nov…

Inducing and Using Alignments for Transition-based AMR Parsing

Andrew Drozdov, Jiawei Zhou, Radu Florian +4

Transition-based parsers for Abstract Meaning Representation (AMR) rely on node-to-word alignments. These alignments are learned separately from parser training and require a compl…

CBR-iKB: A Case-Based Reasoning Approach for Question Answering over Incomplete Knowledge Bases

Dung Thai, Srinivas Ravishankar, Ibrahim Abdelaziz +7

Knowledge bases (KBs) are often incomplete and constantly changing in practice. Yet, in many question answering applications coupled with knowledge bases, the sparse nature of KBs…

A Distant Supervision Corpus for Extracting Biomedical Relationships Between Chemicals, Diseases and Genes

Dongxu Zhang, Sunil Mohan, Michaela Torkar +1

We introduce ChemDisGene, a new dataset for training and evaluating multi-class multi-label document-level biomedical relation extraction models. Our dataset contains 80k biomedica…

Knowledge Base Question Answering by Case-based Reasoning over Subgraphs

Rajarshi Das, Ameya Godbole, Ankita Naik +5

Question answering (QA) over knowledge bases (KBs) is challenging because of the diverse, essentially unbounded, types of reasoning patterns needed. However, we hypothesize in a la…
